" The name of the senior author alone leads us to expect 

 much from this volume, and the most careful scrutiny 

 reveals almost no defects. It easily takes first place 

 among histologies, chiefly because of the invaluable com- 

 parative element. With few exceptions, histologies, in- 

 tended as they have been primarily for the medical student, 

 have heretofore been based for the most part on the genus 

 Homo. Morphologists and anatomists will welcome a 

 general histology which in the widest sense holds to its 

 title, treating its subject as a pure science. . . . One 

 can scarcely imagine a clearer or better arranged text-book 

 either for the general student or for the specialist in any 

 of the many related sciences. Since scientists in many 

 fields often have occasion to refer to or to verify some 

 point in histology, the volume will appeal to readers out- 

 side of the domain of histology proper." New York 

 Evening Post. 



" In marked contrast to practically all the text-books of 

 histology in the English language, which deal largely or 

 exclusively with human or mammalian structures, this new 

 book discusses the tissues of all classes of animals. It is 

 therefore possible to treat the subject much more broadly 

 and satisfactorily than has hitherto been done." Ameri- 

 can Journal of Science. 



" When one considers the narrow, technical training which 

 students in histology usually receive, whether they be 

 medical students or not, one cannot but wish that a course 

 similar to that outlined in this book might be given in 

 every college and university." Science.
