Some other methods of manifold writing, such es the Edison, the Trypograph, the Cyclostyle, &c. (by which 1,000 copies can be taken from one writing), do not possess this fault, being based on a principle of a fine stencil on prepared paper, and squeezing ink through the minute perforations on to a sheet of paper fixed underneath. The writing in these stencil systems, however, has a "dotty" and broken appearance, displeasing to many eyes—the Cyclostyle being, perhaps, least faulty in this respect. For those who would like to make a gelatine "graph," we append the following recipe:
Six parts by weight of pure glycerine, four parts by weight of water, two parts of barium sulphate, and one part of sugar. Mix them, and let them soak for twenty-four hours; then melt at a gentle heat, stir until thoroughly mixed, and pour the composition into a tray. Any chemist will supply an aniline dye for the ink.

2487. Cements
The term "cement" includes all those substances employed for the purpose of causing the adhesion of two or more bodies, whether originally separate, or divided by an accidental fracture. As the various substances that may require cementing differ very much in texture, &c., a number of cements possessed of very different properties are required, because a cement that answers admirably under one set of circumstances may be perfectly useless in others. The general principles upon which the success or failure of cementing usually depends are:
The different parts of a solid are held together by an attraction between their several particles, which is termed the attraction of cohesion. This attraction acts only when the particles are in the closest possible contact: even air must not be between them. If, after breaking any substance, we could bring the particles into as close a contact as before, and perfectly exclude the air, they would re-unite, and be as strongly connected as ever. But in general this is impossible: small particles of grit and dust get between them; the film of interposed air cannot be removed; and thus, however firmly we press the edges of a broken cup together, it remains cracked china still.
The cohesion between the particles of the cement is very much less than the adhesion of the cement to other bodies; and if torn apart, the connected joint gives way, not by the loosening of the adhesion, but by the layer of cement splitting down the centre. Hence the important rule that the _less_ cement in a joint the stronger it is. To unite broken substances with a thick cement is disadvantageous, the object being to bring the surfaces as closely together as possible. The general principles that ought always to be borne in mind having been mentioned, the manufacture and uses of some of the more useful cements may be described.
2488. Mouth Glue
The very useful preparation sold under this title is merely a thin cake of soluble glue, which, when moistened with the tongue, furnishes a ready means of uniting papers, &c. It is made by dissolving one pound of fine glue or gelatine in water, and adding half a pound of brown sugar, boiling the whole until it is sufficiently thick to become solid on cooling; it is then poured into moulds, or on a slab slightly greased, and cut into the required shape when cool.

Economy is the Household Mint.
2489. Paste
Paste is usually made by rubbing up flour with cold water, and boiling; if a little alum is mixed before boiling it is much improved, being less clammy, working more freely in the brush, and thinner, a less quantity is required, and it is therefore stronger. If required in large quantity, as for papering rooms, it may be made by mixing one quartern of flour, one quarter pound of alum, and a little warm water; when mixed, the requisite quantity of boiling water should be poured on whilst the mixture is being stirred. Paste is only adapted to cementing paper; when used it should spread on one side of the paper, which should then be folded with the pasted side inwards, and allowed to remain a few minutes before being opened and used; this swells the paper, and permits its being mere smoothly and securely attached. If kept for a few days, paste becomes mouldy, and after a short time putrid; this inconveince may be obviated by the use of:
2490. Permanent Paste
Permanent Paste, made by adding to each half-pint of flour paste without alum, fifteen grains of corrosive sublimate, previously rubbed to powder in a mortar, the whole to be well mixed; this, if prevented from drying, by being kept in a covered pot, remains good any length of time, and is therefore convenient; but unfortunately it is extremely poisonous, though its excessively nauseous taste would prevent its being swallowed accidentally. It possesses the great advantage of not being liable to the attacks of insects.
2491. Liquid Glue
The liquid glue of the shops is made by dissolving shellac in water, by boiling it along with borax, which possesses the peculiar property of causing the solution of the resinous lac. This preparation is convenient from its cheapness and freedom from smell; but it gives way if exposed to long-continued damp, which that made with naphtha resists.
2492. Common Glue
Of the use of
common glue
very little need be said; it should always be prepared in a gluepot or double vessel, to prevent its being burned, which injures it very materially. The chief objection to the use of this contrivance is, that it renders it impossible to heat the glue in the inner vessel to the boiling point; this, however, can be obviated by employing in the outer vessel some liquid which boils at a higher temperature than pure water, such as a saturated solution of salt (made by adding one-third as much salt as water). This boils at 224° Fahr., 12° above the heat of boiling water, and enables the glue in the inner vessel to be heated to a much higher temperature than when pure water is employed. If a saturated solution of nitre is used, the temperature rises still higher.
2493. Diamond Cement
Soak isinglass in water till it is soft; then dissolve it in the smallest possible quantity of proof spirit, by the aid of a gentle heat; in two ounces of this mixture dissolve ten grains of ammoniacum, and whilst still liquid add half a drachm of mastic, dissolved in three drachms of rectified spirit; stir well together, and put into small bottles for sale.
Directions for Use
.— Liquefy the cement by plunging the bottle in hot water, and use it directly. The cement improves the oftener the bottle is thus warmed; it resists the action of water and moisture perfectly.
2494. Rice Flour Cement
An excellent cement may be made from rice flour, which is at present used for that purpose in China and Japan. It is only necessary to mix the rice flour intimately with cold water, and gently simmer it over a fire, when it readily forms a delicate and durable cement, not only answering all the purposes of common paste, but admirably adapted for joining together paper, cards, &c., in forming the various beautiful and tasteful ornaments which afford much employment and amusement to the ladies. When made of the consistence of plaster-clay, models, busts, bas-relievos, &c., may be formed of it; and the articles, when dry, are susceptible of high polish, and are very durable.
2495. Using Egg
The white of an egg, well beaten with quicklime, and a small quantity of very old cheese, forms an excellent substitute for cement, when wanted in a hurry, either for broken china or old ornamental glassware.
2496. Cement for Broken China, Glass, &c.
This cement being nearly colourless, possesses advantages which liquid glue and other cements do not.—Dissolve half an ounce of gum acacia, in a wineglass of boiling water; add plaster of Paris sufficient to form a thick paste, and apply it with a brush, to the parts required to be cemented together.
At Night Nature is in Mourning for the Loss of the Sun.
2497. Lime and Egg Cement
Lime and Egg Cement is frequently made by moistening the edges to be united with white of egg, dusting on some lime from a piece of muslin, and bringing the edges into contact. A much better mode is to slake some freshly-burned lime with a small quantity of
boiling
water; this occasions it to fall into a very fine dry powder, if excess of water has not been added. The white of egg used should be intimately and thoroughly mixed, by beating with an equal bulk of water, and the slaked lime added to the mixture, so as to form a thin paste, which should be used speedily, as it soon sets. This is a valuable cement, possessed of great strength, and capable of withstanding boiling water. Cements made with lime and blood, scraped cheese, or curd, may be regarded as inferior varieties of it.
2498. White Lead as Cement
Cracked vessels of earthenware and glass may often be usefully, though not ornamentally, repaired by white lead spread on strips of calico, and secured with bands of twine.
2499. Marine Glue
In point of strength, all ordinary cements yield the palm to Jeffery's Patent Marine Glue, a compound of India-rubber, shellac, and coal-tar naphtha. Small quantities can be purchased at most of the tool warehouses, at cheaper rates than it can be made. The colour of this glue, however, prevents its being much used.
2500. Coaguline
An exceedingly strong, and at the same time a transparent and colourless cement is made by Messrs. Kay Brothers, of Stockport, and is sold by most fancy stationers and chemists under the name of Coaguline. It is easily and quickly applied, and will be found extremely serviceable in repairing glass, china, and stone articles. It is inexpensive.
2501. Red Cement
Red Cement which is employed by instrument makers for cementing glass to metals, and which is very cheap, and exceedingly useful for a variety of purposes, is made by melting five parts of black rosin, one part of yellow wax, and then stirring in gradually one part of red ochre or Venetian red, in fine powder, and previously
well dried
. This cement requires to be melted before use, and it adheres better if the objects to which it is applied are warmed.
2502. A Soft Cement for Corks
A soft cement, of a somewhat similar character to that just described, is useful for covering the corks of preserved fruit, and other bottles. It is made by melting yellow wax with an equal quantity of rosin, or of common turpentine (not oil of turpentine, but the resin), using the latter for a very soft cement, and stirring in, as before, some dried Venetian red.
2503. Mastic Cement
This is employed for making a superior coating to inside walls, but must not be confounded with the
resin mastic
. It is made by mixing twenty parts of well-washed and sifted sharp sand with two parts of litharge and one of freshly burned and slaked quicklime, in fine _dry_ powder. This is made into a putty, by mixing with linseed oil. It sets in a few hours, having the appearance of light stone; and we mention it, as it may be frequently employed with advantage in repairing broken stone-work (as steps), by filling up the missing parts. The employment of Roman cement, plaster, &c., for masonry work, hardly comes within the limits of Domestic Manipulation.
2504. Cement for Leather and Cloth
An adhesive material for uniting the parts of boots and shoes, and for the seams of articles of clothing, may be made thus:—Take one pound of gutta-percha, four ounces of India rubber, two ounces of pitch, one ounce of shellac, two ounces of oil. The ingredients are to be melted together, and used hot.
Go to Bed with the Lamb and Rise with the Lark.
2505. Birdlime
Take any quantity of linseed oil, say half a pint; put it into an old pot, or any vessel that will stand the fire without breaking—the vessel must not be more than one-third full; put it on a slow fire, stir it occasionally until it thickens as much as required; this will be known by cooling the stick in water, and trying it with the fingers. It is best to make it rather harder than for use. Then pour it into cold water. It can be brought back to the consistency required with a little Archangel tar.
2506. Anglo-Japanese Work
This is an elegant and easy domestic art. Take yellow withered leaves, dissolve gum, black paint, copal varnish, &c. Any articles, such as an old tea-caddy, flower-pots, fire-screens, screens of all descriptions, work-boxes, &c., may be ornamented with these simple materials. Select perfect leaves, dry and press them between the leaves of books; rub the surface of the article to be ornamented with fine sand paper, then give it a coat of fine black paint, which should be procured mixed at a colour shop.
When dry rub smooth with pumice-stone, and give two other coats. Dry. Arrange leaves in any manner and variety, according to taste. Gum the leaves on the under side, and press them upon their places. Then dissolve some isinglass in hot water, and brush it over the work. Dry. Give three coats of copal varnish, allowing ample time for each coat to dry. Articles thus ornamented last for years, and are very pleasing.
2507. Ornamental Leather Work
An excellent imitation of carved oak, suitable for frames, boxes, vases, and ornaments in endless variety, may be made of a description of leather called basil. The art consists in simply cutting out this material in imitation of natural objects, and in impressing upon it by simple tools, either with or without the aid of heat, such marks and characteristics as are necessary to the imitation. The rules given with regard to the imitation of leaves and flowers apply to ornamental leather work. Begin with a simple object, and proceed by degrees to those that are more complicated.
Cut out an ivy or an oak leaf, and impress the veins upon it; then arrange these in groups, and affix them to frames, or otherwise. The tools required are ivory or steel points of various sizes, punches, and tin shapes, such as are used for confectionery. The points may be made out of the handles of old tooth-brushes. Before cutting out the leaves the leather should be well soaked in water, until it is quite pliable. When dry, it will retain the artistic shape. Leaves and stems are fastened together by means of liquid glue, and varnished with any of the drying varnishes, or with sealing-wax dissolved to a suitable consistency in spirits of wine. Wire, cork, gutta-percha, bits of stems of trees, &c., may severally be used to aid in the formation of groups of buds, flowers, seed-vessels, &c.
2508. Black Paper Patterns
Mix some lamp-black with sweet oil. With a piece of flannel cover sheets of writing-paper with the mixture; dab the paper dry with a bit of fine linen. When using, put the black side on another sheet of paper, and fasten the corners together with small pins. Lay on the back of the black paper the pattern to be drawn, and go over it with the point of a steel drawing pencil: the black will then leave the impression of the pattern on the undersheet, on which you may draw it with ink.
2509. Patterns on Cloth or Muslin
Patterns on cloth or muslin are drawn with a pen dipped in stone blue, a bit of sugar and a little water; wet to the consistence wanted.
2510. Feather Flowers: Materials
Procure the best white swan or goose feathers; have them plucked off the fowl with care not to break the web; free them from down, except a small quantity on the shaft of the feather. Get also a little fine wire, different sizes; a few skeins of fine floss silks, some good cotton wool or wadding, a reel of No. 4 Moravian cotton, a skein of Indian silk, some starch and gum for pastes, and a pair of small sharp scissors, a few sheets of coloured silk paper, and some water colours.
Eating and Drinking Shouldn't Keep Us from Thinking.
2511. Patterns for Petals
Having procured two good specimens of the flower you wish to imitate, carefully pull off the petals of one, and, with a piece of tissue paper, cut out the shape of each, taking care to leave the shaft of the feather at least half an inch longer than the petal of the flower. Carefully bend the feather with the thumb and finger to the proper shape; mind not to break the web.
2512. Stem and Heart of a Flower
Take a piece of wire six inches long; across the top lay a small piece of cotton wool, turn the wire over it, and wind it round until it is the size of the heart or centre of the flower you are going to imitate. If a single flower, cover it with paste or velvet of the proper colour, and round it must be arranged the stamens; these are made of fine Indian silk, or feathers may be used for this purpose. After the petals have been attached, the silk or feather is dipped into gum, and then into the farina. Place the petals round, one at time, and wind them on with Moravian cotton, No. 4. Arrange them as nearly like the flower you have for a copy as possible. Cut the stems of the feathers even, and then make the calyx of feathers, cut like the pattern or natural flower. For the small flowers the calyx is made with paste. Cover the stems with paper or silk the same as the flowers; the paper must be cut in narrow strips, about a quarter of an inch wide.
2513. Pastes of Calyx, Hearts, and Buds of Flowers
Take common white starch and mix it with gum water until it is the substance of thick treacle; colour it with the dyes used for the feathers, and keep it from the air.
2514. To make the Farina
Use common ground rice, mixed into a stiff paste with any dye; dry it before the fire, and when quite hard, pound it to a fine powder. The buds, berries, and hearts of some double flowers are made with cotton wool, wound around wire, moulded to the shape with thumb and finger. Smooth it over with gum water, and when dry, cover the buds, berries, or calyx with the proper coloured pastes; they will require one or two coats, and may be shaded with a little paint, and then gummed and left to dry.
2515. Flowers of Two or More Shades
Flowers of two or more shades are variegated with water colours, mixed with lemon juice, ultramarine and chrome for blue; and to produce other effects, gold may also be used in powder, mixed with lemon juice and gum water.
2516. To Dye Feathers Blue
Into two pennyworth of oil of vitriol mix two pennyworth of the best indigo in powder; let it stand a day or two; when wanted shake it well, and into a quart of boiling water put one tablespoonful of the liquid. Stir it well, put the feathers in, and let them simmer a few minutes.
2517. Yellow
Put a tablespoonful of the best turmeric into a quart of boiling water; when well mixed put in the feathers. More or less of the turmeric will give them different shades, and a very small quantity of soda will give them an orange hue.
2518. Green
Mix the indigo liquid with turmeric, and pour boiling water over it; let the feathers simmer in the dye until they have acquired the shade you want them.
2519. Pink
Three good pink saucers in a quart of boiling water, with a small quantity of cream of tartar. If a deep colour is required, use four saucers. Let the feathers remain in the dye several hours.
2520. Red
In a quart of boiling water dissolve a teaspoonful of cream of tartar; put in one tablespoonful of prepared cochineal, and then a few drops of muriate of tin. This dye is expensive, and scarlet flowers are best made with the plumage of the red ibis, which can generally be had of a bird-fancier or bird-stuffer, who will give directions how it should be applied.
We Seldom Repent of Having Eaten Too Little.
2521. Lilac
About two teaspoonfuls of cudbear into about a quart of boiling water; let it simmer a few minutes before you put in the feathers. A small quantity of cream of tartar turns the colour from lilac to amethyst.
2522. Black; Crimson
See Instructions upon Dyeing, par.

et seq,
2523. Preparation of Feathers for Dyeing
The feathers must be put into hot water, and allowed to drain before they are put into the dyes. After they are taken out of the dye, rinse them two or three times in clear cold water (except the red, which must only be done once), then lay them on a tray, over which a cloth has been spread, before a good fire; when they begin to dry and unfold, draw each feather gently between your thumb and finger, until it regains its proper shape.
2524. Leaves of the Flowers
These are made of green feathers, cut like those of the natural flower, and serrated at the edge with a very small pair of scissors. For the calyx of a moss-rose the down is left on the feather, and is a very good representation of the moss on the natural flower.
2525. Waxen Flowers and Fruit
There is no art more easily acquired, nor more encouraging in its immediate results, than that of modelling flowers and fruit in wax. The art, however, is attended by this draw-back—that the materials required are somewhat expensive.
2526. Materials for Wax Flowers
The appliances required for commencing the making of waxen flowers will cost from 20s. to 30s., and may be obtained at most fancy repositories in large towns. Persons wishing to commence the art would do well to inquire for particulars, and see specimens of materials; because in this, as in every other pursuit, there are novelties and improvements being introduced, which no book can give an idea of.
2527. Petals and Leaves of Wax Flowers
Petals and leaves of wax flowers are made of sheets of coloured wax, which may be purchased in packets of assorted colours.
2528. Stems
The stems are made of wire of suitable thicknesses, covered with silk, and overlaid with wax; and the leaves are frequently made by thin sheets of wax pressed upon leaves of embossed calico. Leaves of various descriptions are to be obtained of the persons who sell the materials for wax flower making.
2529. Models for Wax Flowers
Ladies will often find among their discarded artificial flowers, leaves and buds that will serve as the base of their wax models.
2530. Natural Models for Wax Flowers
The best guide to the construction of a flower—far better than printed diagrams or patterns—is to take a flower, say a
tulip
, a
rose
, or a
camellia
. If possible, procure
two
flowers, nearly alike; and carefully pick one of them to pieces; lay the petals down in the order in which they are taken from the flower, and then cut paper patterns from them, and number them from the centre of the flower, that you may know their relative positions.
2531. Putting Petals Together
The perfect flower will guide you in getting the wax petals together, and will enable you to give, not only to each petal but to the
contour
of the flower, the characteristics which are natural to it. In most cases, they are merely pressed together and held in their places by the adhesiveness of the wax. From the paper patterns the wax petals or other portions of the flowers may be cut. They should be cut singly, and the scissors should be frequently dipped into water, to prevent the wax adhering to the blades.
