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 that it is the most 

 valuable text-book for the zoological student which has appeared since 

 Balfour's book, and is a worthy successor to it. The mass of literatim-, 

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

 Drs. Korschelt and Heider have carefully gone over it all ; and not 

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

 to the subject in hand, citing authority for every statement made, so 

 that the student can go to original treatises for fuller detail. I do not 

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

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

 produce a work which shall be a complete and trustworthy guide to 

 the recent literature of a prodigiously prolific subject. There can be 

 no doubt that we have in this new treatise on Comparative Embryology 

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

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

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



Professor E. Ray Lankester in Nature. 



" The translators have performed their task with skill. The German 

 idiom is quite got rid of, and the book in its English form is eminently 

 lucid and readable. The translators are to be congratulated on their 

 work, and have earned the gratitude of all English zoologists. It only 

 remains to say that the book is well got up ; the printing is good, the 

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



"The translation of this important work into English will be welcona-il 

 by all students of animal morphology, for since the appearance of 

 Balfour's classical treatise on this subject, there has been no one work 

 of importance comprehensively dealing with a vast array of facts, many 

 of which, unfortunately, are still isolated and unconnected. We con- 

 gratulate the authors on the successful accomplishment of their task 

 and on their successful translation of many phrases of great idiomatic 

 difficulty." — British Medical Journal.
