SOME OPINIONS OF THE PRESS. 



•'The best idea which can be given of the scope and value of this 

 work is obtained when we compare it with Frank Balfour's treatise on 

 Comparative Embryology. It is not too much to say thai it is the i 

 valuable text-book for the zoological student which has appear* 

 Balfour's book, and is a worthy successor in it. Tin- ma- of literature, 

 vast as it was ten years ago, has increased enormously in tin- interval. 

 Drs. Korschelt and Heider have carefully gone over it all ; and 

 only that, but they accurately and clearly give each author's contribution 

 to the subject in hand, citing authority for every statement m 

 that the student can go to original treatises for fuller detail. I do 

 know of any scientific treatise which shows so clearly the author's 

 to do justice to every fellow -worker, of whatever nationality, 

 produce a work which shall be a complete and trustworthy guid< 

 the recent literature of a prodigiously prolific subject. There 

 no doubt that we have in this new treatise on Comparative Embryo] 

 one of those invaluable, indispensable works for the production "t which 

 authors receive the gratitude and esteem of their fellow-workers in all 

 lands. It is a truly first-rate book."

"The translators have performed their task with .-kill. The German 

 idiom is quite got rid of, and the book in its English form i- eminent!} 

 lucid and readable. The translators are to dated on theii 



work, and have earned the gratitude of all English zoologists. [1 

 remains to say that the book is well got up; the printi the 



illustrations are excellent, and the size is convenient. " — A ! 



"The translation of this important work in ish will 



by all students of animal morphology, for since tin- apj 

 Balfour's classical treatise on this subject, there has been i. 

 of importance comprehensively dealing with 

 of which, unfortunately, are still isolated and 

 gratulate the authors on the successful accomplish] 

 and on their successful translation of many pin 

 difficulty." — British Medical Jouri
