career. However, as all of the books mentioned below should be in 

 every College Library, those who wish such bibliographies can find the 

 best of them in Kellicott's "Chordate Development," Patten's "The 

 Early Embryology of the Chick," and Kingsley's "Comparative Anatomy 

 of Vertebrates." 



It is much more important for the student to know HOW to Com- 

 pile a Bibliography than to look over one already made. Therefore at 

 Marquette University a different subject is assigned each student to 

 look up for the purpose of compiling a bibliography of everything writ- 

 ten on that subject for the past forty years. Such subject may be taken 

 from any Index of the Journal of the American Medical Association. 



Forty years are chosen because it is about that many years ago that 

 some of the larger indices were compiled, and it is essential that the stu- 

 dent be forced to go through all the indices year by year. If the indices 

 are not found in the smaller towns and cities, the bibliography can be 

 made during one of the vacations when the student passes through some 

 of the larger cities where there is a Medical or Scientific Library. 



The more important Indices published in the English Language are : 



The Zoological Record (published yearly by the Zoological Society of London. 

 Each volume gives a complete list of the works and publications relating to 

 zoology in all its branches that have appeared during the preceding year. The 

 first volume was for the year 1864). 



The Index Medicus (Found in any Medical Library). 



Index Catalogue of the Surgeon General's Office. 



International Catalogue of Scientific Literature, "Zoology," "Botany," ''General 

 Biology." (Pub. by Harrison &.Sons, 45 St. Martin's Lane, London.)
