The three fundamental, as well as original, 

 works here mentioned brought the author the 

 appointment to the first International Guest- 

 Lectureship ever extended by the National Uni- 

 versities and the Learned Societies of the great 

 nations of South America, to a North American 

 biologist. The same works also brought him 

 membership in various distinguished foreign sci- 

 entific societies. 



The Report of Eminent Men on the 

 Above Work 



The foremost leaders in seven fields of science 

 — Biology, Embryology, Comparative Anatomy, 

 Neurology, Medicine, and even Etymology — 

 have written personal letters to the author or 

 publishers, or have written long and glowing 

 commendations in the leading scientific journals 

 of four continents, regarding the originality, 

 worth, comprehensiveness, and clarity of the 

 books mentioned above. Among such men we

 A. Locy, and a host of others.

 GENERAL AND PROFESSIONAL BIOLOGY 

 as a pioneer work in "that it marked a new de- 

 parture in the teaching of biology" and recom- 

 mending it "for wide acceptance as a textbook 

 in high schools, colleges, and pre-medical schools."
