lo Courses Giveti by 



Vertebrate Zoology, the number taking physiology represents 

 the total number of different students taught. 



In zoology and neurology the totals represent different indi- 

 viduals, but as they had previously taken physiology they are 

 represented in the total for physiology. As special and labo- 

 ratory work extends throughout the year and may be taken 

 more than one year, the total in the last column represents 

 more or less duplication. Probably about 450 different stu- 

 dents have taken laboratory work, and .special courses. 



Since 1885-86 the courses in Anatomical and Microscopical 

 Methods, Histology and Embryology , while under the general 

 direction of Professor Wilder, were not personally conducted 

 by him, hence the students taking those courses are not in- 

 cluded in the table. 



Under laboratory and special lecture courses, are in- 

 cluded lectures and laboratory work in comparative anat- 

 omy, collecting, preserving and mounting specimens, mu- 

 seum methods, systematic zoological work, practical anatomy, 

 embryology, vertebrate homologies, and philosophical anat- 

 omy. 



From the beginning the general courses of Phj'siology and 

 Zoology have been abundantly illustrated bj' lecture-room 

 experiments and the exhibition of specimens and preparations 

 as well as by special demonstrations ; but in 18S0-81 in Zoolo- 

 gy, and 1886-87 in Physiology, in addition to the experi- 

 ments and demonstrations given by Professor Wilder, he in- 

 troduced for these large and general classes practical labora- 

 tory work, or " Practicums," as he designated the work. 

 That is, two thirds of the time devoted to the study was given 

 to lectures and one third to the laboratory work in which 

 the students were trained in gaining knowledge by actual 

 personal investigation. 



Until 1888-89 Physiology included also Hygiene, and Zoolo- 

 gy included both Vertebrates and Invertebrates until 1876-77. 

 Since that time Dr. Wilder's course in zoology has been ex- 

 clusively vertebrate. In 1870-71 a course in ''Comparative 

 Neurology was given, but it was not until 1875-76 that 

 Vertebrate Neurology became an established course. It was 

 called by different names in different j^ears, as "comparative
