An anthology of Leonardo’s work in literature comprising the record and results of his studies in the theory of art together with fragments of literary composition of a philosophical or imaginative character, and much personal and biographical matter.
“His translation is always lucid, when the original permits it to be so.”
“We have observed only two errors In Mr. McCurdy’s contributions to the volume.”
“The collection of the great Italian’s notes should be put into the hands of every young artist—indeed, one might say of every man.”

“After recounting with brevity the influences of heredity and environment which acted upon Huxley’s early years, the author sets forth and discusses his teachings in biology, theology, education, morals, and psychology, and concerning individual rights and the gospel of work. He believes that two main forces were at work throughout Huxley’s life—‘the one that of the scientific investigator, full of enthusiasm, dominant, persevering, toiling arduously day by day.... The other that of the polemical philosopher, fond of arguments, combative ... fighting ... partly for victory, partly for the upholding of what he deemed a principle of ideal.’”—N. Y. Times.
“A sympathetic interpretation.”
“The book is written impartially, recognizing fully the philosopher’s great services to scientific advancement, but discussing freely the flaws in his theories.”

“After a general survey of the historical material, Professor De Vries examines the work of these two men in the light of recent discoveries in heredity and hybridization, and uses their results to test the Darwinian theory and the mutation theory, and finds all the data in favor of the latter.”—Lit. D.
“Can be heartily commended to the practical farmer and gardener as well as to the scientific student.”
“The book is one that can be confidently commended to the notice of the practical plantbreeder as well as to the students of science.”
“It is a compact and popular presentation of the recent wonderful development in methods of plant breeding, and a clear statement of the bearing of all this vast experimental work upon the author’s theory of mutation. Altogether, the book is full of pregnant suggestions, and should do much toward clearing up some of the evident confusion concerning the views of the distinguished author.” J. M. C.
“The volume is clearly and pleasantly written, and as the forms of plant-life discussed are those in which there is much general interest,—such as wheat, oats, corn, and various fruits,—it may be read with satisfaction and profit by all.”
“The chapter on the association of characters—correlation biologists usually call it—is simply rich in its array of facts and its suggestiveness, and the keen analysis of the methods and results of plant amelioration is equally admirable. The whole book is perfectly comprehensible by the general reader.”
“This book is one of the most valuable contributions to botanical science that has appeared in recent years. It will be widely read because of the clear scientific discussion of the principles that underlie plant breeding.” Carlton C. Curtis.
“The book is full of valuable information for the live farmer, the gardener, nurseryman, or seed-grower, as well as for the student of evolution and the lover of plants.”
“The volume can be heartily recommended as an interesting and safe guide to amateurs who desire to examine more closely the variant plants around them.”

“Very few changes are to be seen in the new edition.... The few errors of the first edition have been corrected, and some alterations have been made for the sake of clearness.”—Bot. Gaz.
“The most important new feature is an explanatory note on variations in ‘Oenothera biennis.’” H. C. Cowles.
“All the misprints that we pointed out in our review of the first edition have been corrected; and even our suggestion that uniformity in the termination of the adjectives derived from such terms as physiology was desirable has been adopted. But, curiously enough, the uniformity is intra-verbal and not inter-verbal. There is no need to commend the book. It is indispensable, inasmuch as it is the only available account of Prof, de Vries’s work in English, so far.” A. D. D.
