The courses of instruction were considerably modified both by 

 the withdrawal of courses formerly offered and by the addition of 

 new ones. Zoology 10a ("Influences of the environment on 

 animal form") and 106 ("The nature and cause of sex"), 

 which had been bracketed for 1907-08, were withdrawn by Pro- 

 fessor Castle, who also withdrew Zoology 116 ("Natural history 

 of the domesticated animals"), formerly given in the second 

 half-year, and transferred Zoology 11a to the second half-year. 

 Professor Parker substituted for Zoology 13 and Zoology 14 (" Com- 

 parative histology"), formerly given in alternation with each other, 

 two half-courses designated as 14a ("Sensory reactions of ani- 

 mals") and 14c ("Comparative histology, with special reference 

 to nervous tissues"). These are likewise offered to alternate 

 with each other. The course for 1908-09 was Zoology 14c. He 

 also changed the numbering of the courses 15 and 16 to 146 and 14a 7 , 

 respectively, and at the same time condensed the titles of the 

 courses without altering their scope. 



Of four new courses, two were offered by Professor Wheeler and 

 Mr. Hayhurst (Zoology 7a, "Anatomy, development, and classi- 

 fication of insects," and Zoology 76, "Habits and distribution of 

 insects"), one by Mr. Hayhurst (Zoology 7c, "Common economic 

 insects and methods of controlling them"), and one by Dr. Rand 

 (Zoology 17. "Morphogenesis. The dynamics of development 

 and growth"). Opportunity for "Research in economic entomol- 

 ogy" — as Zoology 20/ — was offered by Professor Wheeler. 



In Zoology 1, given by Professor Parker, weekly tests were, sub- 

 stituted for the November examination; but the results do not 

 warrant the change. The laboratory exercises were considerably 

 altered, among other things a study in comparing the external
