SEVEN YEARS OFF.The Corner Teeth without showing age,exhibit further evidence of wear.
EIGHT YEARS OFF.The Gum of the lower Corner Teeth hasbecome Square, and the lower Tush blunt.
51.At eight years off, the gum of the lower corner tooth has become square, and the lower tush blunt.The original drawing was made from the teeth of that noted horse, Oakley; and in order to render it as perfect as possible, the mouths of mares (Meal, Edgworth, Bess, &c.) have been compared. The departure from the circular form of the gum, as depicted in the coloured engraving, is even more marked than it was at the seventh year. Added to this change of figure, the gums appear more hard and less delicate; the mouth looks more firm, and seems to have attained the perfection of its strength. The margin of the lower jaw is now comparatively sharp, and the cheeks are flat. The crusta petrosa on the upper teeth is in a great degree removed; the enamel not yet, however, having a marked yellow tinge. On the lower corner incisors the crusta petrosa may still continue, but it no longer has a dull brown aspect: it is never prominent at this age, but rather speckled over the outer surface, than regularly enveloping any portion of it. It has a somewhat rough and worm-eaten aspect, and in colour is nearer to a dirty yellow than a dull brown. If the posterior angle of theupper corner incisor is pendant, or exhibits that species of notch, which was alluded to in the previous paragraph, it is at the eighth year well shown, and the table has undergone considerable alteration. There is now on the shell tooth, a full table, theinfundibulum of which, if not obliterated, is always of lessened size, well marked out, and on all sides surrounded by a broad and a flattened surface. The other teeth have also changed their figures. The tables of the centre nippers have taken on a decided angular shape, and those of the lateral display no dubious tendency to assume that form. The infundibula may be obliterated, but more generally those in the lateral and corner teeth are retained, or if now absent, the circle of enamel will, on inspection, show that the cavity is only filled up by crusta petrosa, not absolutely worn out. The following wood-cuts exhibit the changes which the tables undergo; and as the eighth year is an important one, inasmuch as the horse which has attained it is called “aged,” a double set is here introduced, to show the difference of figure which these parts may present. In those tables, it will be seen the infundibulum has gone from a centralnipper only; but even in that instance, a white mark indicates that the cavity is merely filled up by crusta petrosa, the enamelled lining not being yet worn out. The alteration in the form and magnitude of the infundibula cannot, if the accompanying wood-cut be compared with those which have preceded it, fail to strike the reader; indeed these changes, aided by the worn appearance of tables of the shell teeth, are now the principal guides when judging of the age by the mouth.
52.After the eighth year, there is no certainty in any opinion drawn from the teeth. A guess may be hazarded, and very often that guess will prove correct, but at the same time it should be received only as a conjecture. The chance of naming the age decreases as the number of years increase. After the twelfth, the probability of hitting the exact yearis very small. After the sixteenth year, all is confusion, and there remains no sign which could warrant any person in pretending he could pronounce the age by the teeth. It is true that certain tokens may induce a conviction that an animal is much older than sixteen, and this conviction may be so justified as to amount almost to a certainty; but no man, I imagine, could form any opinion with regard to the number of years by which a horse exceeded sixteen, or pronounce a decision that should have any appearance of exactitude. They who pretend to an ability of this kind, may, in a few solitary instances, strike the point; but repeated failures will show that there is no positive principle in operation to guide the judgment. Indeed the age is most correctly told during the periods of dentition, and up to the sixth year. After the sixth year, the certainty is not so great, but a very fair, if not a positive judgment can be pronounced until the eighth year is accomplished. After the eighth year, no man should give an unqualified opinion concerning the age of a horse. After the twelfth, whatever may be pronounced should be offered only as a conjecture; and, after the sixteenth, the practitioner had better be silent. When stating this the author must be understood as expressing the conviction at which almost exclusive attention to the subject, and much necessary consideration, has enabled him to arrive. It must not, however, be thought that he is arrogating a power of measuring the capabilities of genius; his wish is only to declare the truth as he perceives it. The intention to publish a work upon the teeth has not been concealed; opinions have been solicited and information sought; the author has many obligations to acknowledge; all to whom he has made application have been liberal in their communications; but from no one has he been able to obtain anything opposed to the conclusions he has here promulgated. It may be that hereafter the power of judging of the age shall be extended. Pessina and the Girards thought it could be done with exactitude up to anextremepoint, and saw a principle in the latest changes which the teeth undergo. The general experience in this country, however, seems to have decided that, after the eighth year, there is no certainty. With that decision the author is reluctantly obliged to acquiesce, and even to add that certainty is not tobe obtained after the sixth year. This limitation, coupled as it is with a confession of inability, may seem to be a backward movement; but truth cannot retrograde. By ascertaining how far our present knowledge leads us, a motive is given to genius by the opportunity created for its exercise. No pains have been spared to investigate the hypotheses which have been made known; they have been candidly put to the test, and on the proof of their inefficiency discarded. That the reader may judge for himself, the tables of teeth, and mouths of various ages are presented. The altered aspect of the tables at the ninth year is indicated in the following wood-cut, which exhibits these surfaces as gaining depth and narrowing from side to side. This appearance they generally assume, and at the same time the infundibula are either lost or much contracted.
The next wood-cut, which depicts the form of the tables at the tenth year, though true in its general character, will serve to show how fardependencemay be placed in ordinary signs, since the infundibulum of the lateral nipper shows a well-marked cavity, while from the other teeth it seems to be upon the eve of disappearing. On inspection, however, it will be seen that in figures the tables approach more towards the square, which is the last form these surfaces assume.
53.At twelve years old, there may be tartar on the lower tush. The teeth are longer, narrower, and the enamel darker.The coloured engraving, which was, on the last occasion justified by a comparison with the mouth of that famous horse, Charles the Twelfth, will convey a general idea of the prevailing characteristics of this age. The teeth have lost the white and firm set aspect they bore at the eighth year. Often, at this period, they have, by wear, become irregular generally, as exhibited in the plate; the grooves, extending down the length of the upper incisors, contain the remnants of the crusta petrosa,which is almost black. The upper tush is usually much diminished, while the lower is long, especially in stallions kept for service. The teeth project more outward and begin to arrange themselves more in a line, no longer showing the crescentic order which they assumed at five years old. Also, by the twelfth year, the tongue, when the jaws are closed, protrudes from the open space between the incisors and molars. The degree in which these alterations have taken place, together with the protrusion of the incisors, is all that is present to guide the judgment; and practical experience is needed, to give him, who attempts to decide upon such weak evidence, any chance of success. As in cases of this description every thing that can help the judgment is eagerly seized upon, the general appearance of the animal is always to be considered; and that may warn the practitioner to modify his opinion. The lower jaw is sharp, the cheeks flat, and around the tushes there may be an accumulation of tartar. It is true the tables, consequent on the wear of the teeth, will have undergone some change, but that alteration is now so slightly marked as not to enforce itself upon the observation. It is easily overlooked, and by nomeans easily recognised. The annexed wood-cut will suggest the nature of the change. In it will be seen a further remove from the oval form of these parts in the young mouth. The surfaces have become square or angular, and the corners are only sufficiently rounded to indicate what once was the shape which they exhibited.
The following wood-cut depicts the tables at the completion of the fourteenth year, and only by careful comparison could the increase of age which they denote be detected. On inspection, however, it will be seen that the irregularities of outline are less prominent even than at the twelfth year.
TWELVE YEARS OLD.Tartar on the lower Tush. The teethlonger, narrower, and the enamel darker.
TWENTY YEARS OLD.The Form of the Mouth changed, and thelower Teeth imperfectly seen from the front.
54.At sixteen years old, when the teeth are viewed from the side, only two incisors can be seen inthe lower jaw, as depicted in the coloured engraving, which was last authenticated by the mouth of Muley Moloch, which favourite stallion I was, by the kindness of Mr. Theobald, permitted to examine at his well-known establishment, where I also saw many other horses of the purest blood and highest promise. Of the excellence of the arrangements and the value of the animals, which give character to that gentleman’s establishment, it would be presumption of me to speak. I have only to express my admiration of what I beheld, and tender my thanks for the attention I received. The engraving, however, was fortunately corroborated, and its general indications may therefore be accepted. The enamel has entirely lost its white and pearly tone. The tushes, perhaps, loaded with tartar in both jaws, are blunt, and generally either very short or long, inclining somewhat outward. The extension of the crescentic arrangement of the lower teeth enables only two to be seen when the parts are viewed from the side. The tongue protrudes to an obvious degree, and the saliva runs from the mouth when the jaws are separated. The edge of the lower jaw is very sharp andsomewhat retracted, while the incisors have taken a horizontal direction. No sign, however, save the protrusion of the tongue, is positive. The general character is that of advanced age, and this general character, at once recognised by the eye of experience, is more to be depended upon than the teeth themselves. The teeth have now assumed the permanent character of old age; and in the figure of the tables will undergo no further alteration upon which anydependencecan be placed. Up to the sixteenth year, however, the tables deserve to be consulted. Below is exhibited such evidence as they present, which the reader will perceive is so nice and delicately marked as to be easily misinterpreted. In the tables which belonged to the fourteenth year, it will be seen the infundibula are almost gone, a speck alone denotes their latest trace; nevertheless, the next wood-cut, which exhibits the tables at the sixteenth year, will show that the absence of the infundibula is not to be relied upon. Still the advance in age is, though feebly, indicated. The central incisor has assumed a form which is peculiarly characteristic of age in the horse. It is seldom that at sixteenyears all the tables take so marked a shape, but some of them, and generally those in the centre, will, at this period, be symbolical of the truth.
Had it not been for the very conspicuous indication of the central tables, the others in the former wood-cut might have been reasonably decided to be more juvenile in their aspect.
55.At twenty years old, the form of the mouth has changed, and the lower teeth are imperfectly seen from the front.This circumstance springs from the more horizontal direction which the teeth have now assumed, and the acuteness of the angle which they consequently form when closed. The engraving also depicts that alteration in position which disables a person, standing in front, from well seeing both rows of incisors when the lips are separated. When the upper incisors are fairly presented to the sight, a partial view only of the lower teeth is obtained,and as the age advances even that is lost. Further inspection also shows additional changes in position, shape, and tint. The grooves are broad, deep, and well marked by their dark colour. Between the upper incisors there are interspaces in which the food has accumulated and become black, giving to the mouth the appearance represented in the coloured plate. The upper tush, which is now of a brownish hue, may be worn to the gum, and the lower continue long and surrounded by tartar, or both may be reduced to mere stumps. The tongue protrudes greatly; the membrane of the mouth seems hard; and no longer vascular, it is thrown into wrinkles. The edge of the lower jaw is sensibly retracted, and its sides are flattened or narrowed. The general appearance indicates the decay of nature. Here again, however, nothing is positive, save the yellowness of the teeth and the protrusion of the tongue. The general character of the animal is of more value than the indications of the mouth; and, persons familiar with horses can, sometimes by this, guess the age of an animal with the same approach to accuracy, which most people exhibit, when pronouncing the extent of an individual’s life, by simplylooking at a man’s face. In neither instance, perhaps, could the basis of the opinion, which possibly shall approach very close to correctness, be accurately stated. Proof, as to the evidence upon which a conclusion is in such cases based, cannot be anticipated, and to the inquiry how they were able to tell the age, each would probably answer, by the “looks,” but neither would be capable of precisely defining in what these “looks” consisted.
56.At thirty years old, the jaws are contracted; the lower are not seen when the upper teeth are in view.The coloured engraving, which at first sight seems to suggest that the animal possessed only a single jaw, exhibits the mouth as it appears at the thirtieth year. The animal, the mouth of which is here depicted, had a lower jaw with excellent teeth considering its age, but without elevating its head these could not, while the mouth was closed, be seen, or when seen, the view of those in the upper jaw was lost. This peculiarity arises from the teeth having taken a still more horizontal inclination; they are now crowded together; and, from the irregularity of their wear, may assume the pointed figure indicatedin the plate. The change of colour also has become more decided, and the general indications, which have been before alluded to, are more marked. After what has been so frequently repeated concerning the deceptive character of the tables in extreme age, little, perhaps, need be added to that subject. Nevertheless, to convey an idea of the appearances which these surfaces may assume, subjoined are wood-cuts taken from authenticated mouths, for the inspection of which I am indebted to the liberality of Mr. Ernes, of Dockhead, who has paid great attention to the changes of the teeth. To the honour of that gentleman, I may, while confessing the heavy obligations under which his generosity has placed me, here mention, that no member of the veterinary profession had, to my knowledge, under his care so great a number of animals working at a period of life when the horse is usually supposed to be worthless. The majority of these were in good condition, active, and capable of doing every kind of ordinary service. They presented a pleasing spectacle, more than creditable to the talent of him under whose charge they had retained health and vigour. The aspects which the tables of the teethexhibited, however, were such as set judgment at defiance, and for the purpose of enabling the reader to form his own opinion on the matter, engravings of a few of them are here introduced.
The above wood-cut exhibits the tables and arrangement of the incisors as they were seen in the mouth of an animal which was proved to be no less than twenty-eight years old. Any one, who should base his opinion solely on the marks, must have pronounced the creature to have been no more than five, since none of the infundibula are lost. The semi-circular arrangement also had suffered no very material change, and altogether the contrast with the next representation of the same parts, as they appeared in the mouth of a horse which was but one year older, is very striking.
In the above engraving the teeth are seen to be ranged almost in a line, which is the form they have a disposition to take at this great age. The appearance, here delineated, is more true than the foregoing in its general character, the infundibula being entirely worn out; for the specks in the centre of the tables show, not the remains of the last portion of the marks, but the exposure of the upper extremity of what once was the cavity of the pulp. In the next wood-cut, however, which depicts the tables of the teeth which were in the jaw of a horse, that had reached its thirtieth year, and from which the drawing for the coloured engraving was made, displays a portion of the infundibulum still retained in the corner incisor. The true character of age nevertheless is conspicuous in the form of the tables.
THIRTY YEARS OLD.The jaw contracted. The lower teeth notseen when the upper are in view.
SIXTEEN YEARS OLD.Viewed from the side, only two Incisorscan be seen in the lower jaw.
Such contradictory indications admit of being to a certain degree reconciled. The representations of the tables are correctly given, but, in the living mouths, these were corrected by the appearances of the teeth themselves. The incisors of the horse which was twenty-eight years old had suffered but little wear. An unusual degree of hardness, or an extraordinary power of self-preservation, contributed to keep them, so far as the tables were concerned, in appearance, young, long after the season of youth had passed. Almost from the fifth year the tables would seem to have suffered but a very gradual change; for even when twenty-eight, these parts do not indicate the horse to be more than “aged.” The absence of wear may, in some measure, be attributed to the kind of food which the animal had consumed, it having been chiefly fed from the manger; and also to its being of a quiet disposition, or not inclined to bite and snap when the groom was dressing it. The want of wear, however, did not necessitate thecessation of growth, which went on at the natural rate; therefore, though the tables had a very youthful look, the teeth were, nevertheless, unusually long, and gave to the mouth a decided appearance of age. Their colour, and the removal of almost everyvestigeof the crusta petrosa, together with the general appearance of the horse, was sufficient to awaken those suspicions which would warn the practitioner. Theeccentricities, however, which particular parts can exhibit, will teach the student, that a conclusion should only be drawn from observation and comparison of all the various signs which the teeth present. No sign can be singly relied on; but, by weighing the evidence, and placing the contradictory indications in opposition, something approaching to truth may, even in extreme age, be deduced; though such deductions, for obvious reasons, ought to be expressed with caution, and never, under any circumstances, positively advanced. Mr. Henderson, the respected veterinary surgeon to Her Majesty the Queen Dowager, possesses in his museum many interesting specimens of the teeth. Among the rest, he has the jaw of an animal which was ascertained to have reached the thirty-eighth year. This preparation, however, exhibits no sign that could characterize the extreme age which the horse had attained, and I allude to it, only as a confirmation of the opinion I have expressed, that, as the period of life advances, the mouth of the horse becomes more and more difficult of interpretation.
57.The tricks, that are practised on the teeth, are so much talked about and so generally feared, that the subject demands a few words in explanation. The breeders are known to extract the milk teeth, hoping thereby to hasten the growth of the permanent incisors, and to increase the apparent age of the colt. The gums they are likewise known to touch with the hot iron, or to freely lance for the same purpose. All of these practices are common enough; but that they accomplish the design of the persons who employ them is not at all certain. By either of these practices the animal is pained, and pain does not favour development, but, on the contrary, retards it. The suffering, however, may be brief, yet the effect does not stop there. If the milk tooth is firm in the mouth, when the attempt is made to extract it, in nineteen cases out of twenty, it willbe broken and the fang left in the jaw. When the extraction of the milk teeth has been general, I have seen numbers of horses, with the broken fangs in their mouths, palpable evidences that the animals have been tampered with. But, supposing all of the tooth to be removed, nothing would be thereby gained. The permanent tooth does not push out the temporary; nor does the temporary, so directly obstruct the coming up of the permanent, as to render its presence or absence of much consequence. If the fang be removed, there may be nothing to absorb, but on that account it does not follow that there will be anything more deposited. The body of a man does not grow larger because one or more of his limbs have been amputated. On the contrary, the shock occasioned to the system by the operation, and the consequence ensuing on the loss of blood, may cause an immediate diminution of the frame. So, if a horse’s tooth be drawn, the animal is alarmed, tortured—and, if the creature recovers from these effects very speedily, so that no loss of growth could be estimated, certainly the most favourable circumstances would not allow us to imagine any stimulus to development had been created. There will besome loss of blood, and this, however slight it may be, nevertheless being taken from the immediate part, must act as a local depletion. Now to deplete is to check growth by abstracting the very source of nutriment. The hemorrhage, however small, must be injurious; and the mouth being made more or less sore, the inclination to feed, as a natural consequence, is diminished, thereby further checking the development. I cannot see in what manner the extraction of the milk teeth is to hasten the growth of the permanent incisors; but I can perceive that the operation may have the opposite effect; and I have known the practice to have been followed by the non-appearance of the very tooth, the protrusion of which through the gum, it was employed to quicken. The tooth, which previously seemed to be on the eve of piercing the gum, after the extraction of the milk incisor never came up,—nor will any person who has thought for an instant, wonder if the violence, necessarily used, does occasionally injure or rupture the delicate vessels and gelatinous tissues of the pulp. More often the breeder’s impatient interference breaks the tooth off at the neck and leaves the fang in the jaw. This he has not the skillto extract, and as it is not afterwards absorbed but speedily assumes a dark colour, it remains a tell-tale and an eye-sore during the life of the animal. Had the colt been left alone, the fang in a few months would, by the natural process, have been absorbed: but the force which broke the tooth, though incapable of extracting it, probably ruptured the delicate tubes of the absorbent vessels. The broken member is left in the mouth, either to act as a foreign body, or to become united by anchylosis to the jaw, and continue for life a deformity. The folly of the practice will surely on reflection be evident to all; and the other means employed for the same end are in a like degree injurious. The breeder will consult his own interest best by studying the feelings of his animals. For the sake of profit, if not for the love of humanity, he had better cease to torture the poor beasts by which he hopes to gain. Suffering will neither engender spirit, growth, or fat, and the market pays price for each of these. The mouth of the horse is too important towards the value of the animal to be ignorantly mutilated. Let the mind reflect, before the hand is permitted even to use the lancet. To lance the gums of the human infant wasonce a favourite practice; nor has the custom at the present time fallen quite into disuse, but it is generally resorted to only during the cutting of the primary teeth, and not commonly adopted to facilitate the appearance of those teeth which the horse-dealer employs it to quicken. In the latter case, on man the gum lancet is not employed; and, if found useless on one animal, a strong inference is created as to the inutility of constantly experimentalizing with the instrument upon another. By incising the gums a wound is created, the part is thickened, and a cicatrix induced; the effects of which are to cause an impediment to the growing tooth; and this being seen and corroborated by practical observation, the best dentists and surgeons of the present day are not very enthusiastic in the use of the gum lancet, which they have in a great measure cast aside, and which is beneficial only in scientific hands. The loss of blood likewise is to be considered, and that certainly aids in retarding the growth, which the adoption of the other means, general with the breeders of horses, could not accelerate. The employment of the cautery, to expedite the appearance of the teeth, is so strange a resort, that I can onlyaccount for the use of that agent by imagining certain persons to be totally ignorant of its action. In the first place, it destroys the part with which it comes in contact; inflammation follows and suppuration ensues; a quantity of blood is diverted to the surface, and of course drawn from the pulp of the new tooth, which originally it flowed to and nurtured. A slough must take place, and the mouth remain sore till the escar is thrown off and the exposed granulating surface cicatrized. But wherever the hot iron is applied the immediate part is thickened, rendered more hard and tense. Which of these effects is it the horse-dealer regards as likely to promote his wishes? A little knowledge would inform any one, that the cautery must act in the opposite direction to that, which it is supposed, by ignorant people, to favour. Indeed, I do not think, that horse-dealers or others have yet obtained so great a mastery over nature, that the dame can be made to hurry at their bidding, however cruelly their orders may be enforced. A “Yorkshire five” may sound well, but there is no more possibility of making a four-year old colt, by barbarity, show the development of a five-year old horse, than there is, by wrenching,cutting, and burning, of making a boy of fifteen look like a man of twenty. Nature obeys her own laws, and is not yet subjected to human practices. Careful rearing, nutritious food, sufficient exercise, and no work does promote development, and of the growth thereby engendered, the purchaser has no reason to be in fear; for if one part shows maturity, he may be assured, that the other parts are also equally matured. The time the animal has lived is not of half the consequence, that the use which has been made of its life is, to the future possessor. The horse that has a mouth indicating five, and that can be proved to be five, if it has been worked from its earliest year and stinted in its food, has less energy and life than a younger creature forwarded by the fostering care of the breeder. The two animals are not to be compared. Supposing the one to be no more than four, it possesses the vigour and development of five; while the other, which is five, may have the decrepitude and constitutional infirmity of twenty. Let not the buyer fear the deceit of the breeder, but without dread accept the mouth as proof of the age; if the animal is not in years, he is in development, that which the teeth declare. Tothis conclusion, however, some will oppose their opinions. The animal, they will argue, has been stimulated to exhibit an unnatural maturity, and the seeds of future disease have thereby been planted in the system; therefore, it will be urged, the worth is depreciated. The statement looks well, but it is of no value, for a little inquiry will prove it to be based on false principles. Excessive stimulus checks the growth, or causes early disease, sacrificing either the health or life of the being. The feeder knows, from experience, that the quantity of nutriment must be measured by the powers of the creature that consumes it; and that over-feeding, by impairing the digestion, destroys or weakens rather than nurtures the body. The stimulus, pushed beyond a certain point, would keep the horse in the infirmary, and never fit it for the market. Every dealer knows this, and though such persons are, by the prejudice of the public, obliged to keep their animals loaded with fat, or in what is called “bloomy condition,” they nevertheless fear to maintain this state of body for too long a period; and while it lasts, constantly resort to drugs, to counteract that tendency to disease which it engenders. They treat their stock, almost as aphysician would treat so many city aldermen; and give dinner or digestive pills almost as regularly. Afattedbeast is always diseased, but an animal liberally fed is thereby rendered the more healthy. In fact, the dread of those results which ensue from comfort is, with regard to the horse, quite as unfounded as the fear, that mankind once had, of the “miseries of the rich,” and the envy, poets taught them to indulge, towards the starvation of the poor. Such idle fancies may be dismissed with profit to the person who discards them; but at the same time there are some practices the reader needs to be cautioned against. To give the face of the horse a youthful appearance, some of the class of dealers who frequent public markets, low auctions, and country fairs, puncture the skin at that part where the falling or depression is seen above the eyes in old animals. Having inserted into the orifice a small quill, they then blow into the part, thereby inflating the subjacent tissue, and concealing the cavity. This notable artifice, which is called “puffing the glym” ought to impose upon no one. Should the trick be suspected, let the hand be carelessly raised to pat the neck and cheek of theanimal, when it can, under pretence of likewise stroking the face, be passed over the part which is supposed to have been tampered with; and in the act a little pressure may be made upon the suspicious region: then, if the swelling has been induced in the manner stated, the passage of the hand is sufficient to squeeze out the air, and the contrast which the two sides of the face will afterwards present, gives to the countenance of the poor horse, a very knowing and peculiar expression. Let the person, however, who thus undertakes to expose roguery, be assured of his ability to protect himself in the office he has assumed; for the gentlemen who display their ingenuity on horses, are not averse to occasionally mutilating the human frame. To lay bare and detect such low, mean, and obvious cheatery, as the above, properly belongs to the police; and the least acute of the force, ought to be equal to the detection of so gross an imposition. The swelling, when caused by inflation, always has an unnatural aspect, such as a school-boy would find no difficulty in recognising, after his attention has been directed to the point. It looks puffed, and when the jaw moves, the part does not play freelywith the motion. These circumstances, at a glance, declare the cheat which the pressure of the hand can, in an instant, prove to have been practised. The artifice, however, when adopted, ought to be of no avail. Young horses often exhibit the depression above the eye, of great depth; nor is it unusual to see old animals, in which the cavity is naturally shallow. The qualified judge, therefore, glances at, but never permits the state of, the part, to influence his decision; and the trick, when resorted to, can impose only on those who are too vain to acknowledge their ignorance, or too mean to pay for protection. Other indications are of greater worth, and to these, observation is directed. The roundness or flatness of the cheek, the sharpness or fulness of the lower jaw, no art can imitate: these, consequently, receive more attention. The eye is directed to the mouth; and still supposing the reader to be present at such places as the parties who practise tricks with horse flesh mostly frequent, let him be thought desirous of purchasing the animal, and therefore proceed with an examination: it will not be long before the teeth will be inspected. When the lips are separated, the incisors may belong and horizontal in their inclination; and, by the time this is noted, the seller probably has volunteered the information, that the horse he is most reluctantly obliged to part from, was six years old last grass. The expression of surprise such a statement elicits, is answered by oaths as to the fact, and direct accusations of ignorance against any one who would assert the animal to be a day older. The jaws are pulled asunder, and all the marks are seen. Here is proof; no man who knows anything of horses, he is told, would reject such evidence; and a host of ready bye-standers stare at the mouth, and only doubt if the creature is full sixyet. The judge also looks at the marks, and then walks away: he has formed his opinion, and the sight of the marks confirms him in the conclusion he had arrived at. The absence of the police may caution him not to expose himself by noticing the shout of defiance, and bellowed taunts, that signalize his retreat; but he has seen the animal is a “bishop.” Now what promoted the poor brute to ecclesiastical dignity? The term in horse slang, simply means that the marks are not natural, but have been made. There are two means by which that can be done. When timepresses, and tools or skill are wanted, the tables of the teeth are touched only with a red hot wire, which leaves a blackmarkwherever it is applied. This, however, is a coarse expedient, and the more usual practice is, to dig out the cavities with a kind of engraver’s tool, and then to blacken the spaces thus created. The infundibula are imitated with much nicity; but the resemblance, however close it may be, never for a moment imposes on the qualified judge. The shape of the table, characteristic of the old tooth, cannot be altered, nor can the edge of enamel, which should gird the infundibulum, be artificially produced. Moreover, many of the people who “bishop” horses, are content to perform the operation only on the lower jaw, leaving the upper teeth untouched, because these are not generally inspected. Should such be the case, of course the marks will be more or less faded, where naturally they would be most fresh; for the infundibula of the lower jaw are lost some years prior to those of the upper disappearing. The attempted deception, therefore, is never successful, save when the “copers” are fortunate enough to meet with a “flat,” who has just knowledge enough to be very wise in his ownconceit. It must, however, be remembered, that the lower class of dealers are not limited in their transactions, and often dispose of animals to persons of respectability; therefore, it is not unusual to find horses standing for sale at commission stables, with mouths of a most conspicuous character. The owners of such horses may be gentlemen of the highest probity, and in ignorance the age may be mis-stated. For this reason, no man should purchase a horse of any individual, without having the animal previously examined by a certificated member of the Royal College of Veterinary Surgeons. The money so spent, is the smallest item in the account; and the sum saved by following this rule is often disproportioned to the expenditure,—to make no estimate of the disappointment and vexation which may be prevented. Respectable dealers will not knowingly allow the character of their stables to be injured by the presence of a “bishoped” animal. This class of persons are very scrupulous in that respect, but they are not always able to detect the truth—their education is often limited, and though good ordinary judges, they cannot, under every circumstance, decide correctly—they unconsciously deceive, being themselves deceived; and consequently every purchaser should take the precaution pointed out, no matter whence, or from whom, he may be buying a horse. Were all to act in the way indicated, much law would be spared, and a great deal of anger allowed to slumber. The dealers are not the rogues the enlightened public are fond of believing—many among them are as honourable as all men should be—some of the class, however, never let a horse escape out of their hands unmutilated. The teeth invariably receive the primary attention: if long, they are, by the application of a file, reduced to the length which the self-taught equine dentist supposes proper to youth. An acid is also applied to the enamelled surface, in order to render it white. No vast good is effected, but if the means were not designed to impose, no great harm would perhaps be done. The acid is not allowed to corrode the tooth, and the diminution of the length may possibly in some degree benefit the animal. The welfare of the creature, however, is not the object sought—the hope is to cheat; but no person who ought to be trusted, or even to trust himself to purchase a horse, should be so imposed upon. Whiteness is no sign of youth inthe tooth of a horse, and the file cannot make the tables assume the juvenile figure. Horses that show such mouths, may be easily recognised—perhaps they are quiet while their legs are handled, but shy when the head is touched—they are not vicious, but timid, and the teeth tell the reason of their fear. It is well to pass them by, and dangerous to accept them at any price. If the teeth have been tampered with, what tricks may not have been practised to conceal other defects?
58.Irregularity of growth in the horse’s teeth, should, in all cases, be early noticed, and speedily attended to, for so much of the worth of the horse depends on the animal’s ability to feed, that it may be said, “no teeth no horse.” The milk teeth are so regular in their growth, that I have not been able to hear of, or meet with a specimen, in which they were eccentric. The permanent teeth, however, are not unusually irregular; the most common irregularity which they exhibit, is that of retention of one or more of the milk incisors, and this more frequentlyis to be seenin the lower than in the upper jaw. Mr. Ernes, of whom I have before spoken as an excellentjudge of the teeth, and a most able practitioner, was kind enough to show me the mouth of a cart horse which was under his care; the lower jaw had eleven incisors, but of these five were milk teeth. The appearance which the mouth presented was rather that of some foreign animal than of an ordinary horse. The bone had become deformed, and the gums were in several places in an inflammatory condition. Mr. Henderson possesses a most curious preparation of the lower jaw of a horse, in which there is exhibited eleven permanent teeth. The appearance which this specimen presents is extraordinary, and the existence of such a monstrosity, showing the extent to which nature may violate her own laws, deserves special attention. The possibility of so great a variation being encountered, will prepare the mind to expect and to consider the less marked deformities, which in practice are not unusually met with. It is not unusual to find horses with eight teeth in one jaw, two of which are generally, on inspection, found to be retained milk incisors. The milk teeth, if allowed to remain after the horse incisors are fairly up, often give to these last a very strange appearance. The followingwood-cut depicts the mouth of a mare, to which my notice was directed by Mr. Henderson, the gentleman to whose generosity I have before had occasion to confess my obligations.
The corner milk tooth here not having been extracted after nature had failed to remove it by the process of absorption, has caused the last permanent incisor to take an unnatural situation, where, being removed from attrition, it has become of extraordinary length, and looks as much like a curious tush as the thing itreally is. Such a state of the mouth is far from rare, and because of its frequency, being the more likely to be met with in practice, it was chosen for illustration. The molar teeth are less subject to distortion, but, nevertheless, are sometimes irregular, and from the same causes. I have seen the palate pierced by a tooth which grew in an unnatural direction. The treatment, in both cases, would be alike. The milk teeth should never be allowed to remain in the mouth after the corresponding permanent teeth are fairly up. If removal prior to this period does no good, now the operation is suggested by its accordance with the natural process, and the sooner it is undertaken the better: any delay will only create difficulty, and render the restoration of the displaced tooth, more problematical. The unabsorbing fang, will, in time, become united to the bone; and if its extraction is then attempted, fracture of the jaw may be the consequence. In no instance should the stable keeper be told to pull out the teeth: he has not the proper instruments for the purpose, and must use unnecessary violence even if he does no greater injury. The animal, besides, is rendered shy of him, in whom it is essential it should be educated torepose confidence; and many a horse, by the bungling efforts of such people, pretending to operate, is ultimately rendered dangerous in the stable. Moreover, the horse owner cannot be too seriously cautioned, against giving permission to those who attend on his animals, to overstep their lawful limits. In the first instance he may, perhaps, congratulate himself upon the result, but speedy experience will convince him, to his cost, of the danger of the system. If the operation should have been delayed so long, as to allow the teeth to have become of unequal lengths, then, after the milk incisors are extracted, the permanent teeth must be rendered level; and, however far apart they may at first be, in time they will approximate. The operation, which is recommended, any Member of the Royal College of Veterinary Surgeons will execute; and, as in skilful hands, it is never dangerous, so it should, on no account, be entrusted to quacks or pretenders. For some irregularities, however, there is no help; for instance, when the lower jaw exhibits only four permanent incisors, which is by no means unusual, and which, in the majority of cases, could be traced to the efforts made to extract the corner milk teeth,before the time had arrived for their removal. An animal with such a mouth is obviously deteriorated. The lessened number of its teeth may be of little consequence while it is young and kept in the stable. During the earlier years, the corner nippers, which are those most frequently wanting, are not in perfect apposition, nor are the incisors of so great importance, when the food is to be pulled from the rack or gathered from the manger. But at grass, especially in old age, when horses are most frequently turned out, and when the spreading of the semi-circle brings all the teeth into play, none can be spared. The absence of one-third of the nippers in the active jaw, would then cause the animal more work for its livelihood, and probably counteract all the benefit which “the run” was intended to produce, even if more serious evils did not ensue. The eccentricities of the teeth should always be regarded, to conjecture how far they may retard the welfare of the horse. The presence of an additional molar in each jaw is sometimes seen, and is hardly to be counted a defect: such supernumerary teeth are generally posteriorly situated, and of small size; they may cause no inconvenience, and theirexistence not be suspected during the life of the animal. The reverse, however, is the case when an extra tooth is found only in one jaw. I am indebted to Mr. Dunsford, a gentleman who pays more than usual attention to every case entrusted to his care, for a fine specimen of the evil which may result from anabnormalmolar. In the lower jaw, on the near side, are seen seven molar teeth; and the last has, from the absence of attrition, grown to a length which caused it to do serious injury to the mouth. The teeth are placed one behind the other in a perfect row; hence, as well as from their all being of the full size, one, the last in position, was occasioned to project, forcing itself through the gum, even into the substance of the superior maxillary bone. The horse was destroyed, having become useless, in consequence of its inability to masticate its food. Another defect in the molars is observed, in these teeth sometimes being placed apart from one another, leaving interspaces between them, in which the food accumulates, and inflaming the gums, causes the animal much pain whenever it attempts to feed. For this, nothing can be done, beyond giving the poor beast its meat artificiallyprepared; but with all care the unfortunate animal becomes emaciated, and is speedily consigned to the knacker. Fortunately, however, the molars are not often irregular in their growth. In fact, most irregularities of the teeth must be carefully sought for, but one form which is not rare by any means ought to be always observed. In certain animals the lower jaw is so short, that the creatures cannot place the incisors together or in apposition: the consequence is, that the lower incisors being active instruments, have to perform their functions at considerable disadvantage; but, nevertheless, they act and receive wear. The upper incisors, however, are, in such mouths, subjected to little attrition; the corner, and a portion of the lateral nippers alone, meeting each other; hence the central nippers, which grow more forward than they ought, at length project downwards, and overhang those of the lower jaw. This arrangement of the incisors constitutes what is called a “parrot mouth,” because of the resemblance which the teeth bear to the bill of the bird. Most old horses are more or less parrot-mouthed; but young horses also occasionally exhibit mouths of this description, and in these last it is certainly a defect, forin a state of nature, or at grass, the animal would be necessitated to tear rather than bite its food. The proprietor of such a beast, therefore, can or ought never to turn the creature out, but keep it constantly in the stable, and under many circumstances this would entail inconvenience and expense. There is nothing to be done for such a malformation, but an allowance should be made for it in the price. That the reader may be able to recognise it, a copy of a mouth, in which the deformity was well marked, is here presented. The animal, which was introduced to my notice by my talented friend, Mr. Broad, of Paddington, was twenty-one years of age; and though more conspicuous cases of the kind are sometimes seen, the one I have chosen for illustration shows a rather greater malformation than is usually met with; but, nevertheless, it well illustrates the point upon which I have been dwelling.
