10 A.NNUAL REPORT OF THE 



the Lawrence Scientific School, or the Graduate School of Applied 

 Science. The first table gives the indicated information for Harv- 

 ard, the second for RadcTifi'e. 



Except for courses which alternate with each other, the formal 

 instruction has not been materially changed from that of the pre- 

 ceding year. 



Professor Parker had as chief assistant in the laboratory for 

 Zoology 1 in Harvard Mr. E. D. Congdon, and as sub-assistants 

 Dr. H. B. Bigelow, Messrs. W. S. Burgess, H. S. Davis, F. F. 

 Marshall, and W. E. Wing. The laboratory work in Radcliffe 

 was in charge of Mr. M. Copcland, as assistant. 



Assistant Professor Castle thinks that a decrease in the number 

 of students in Zoology 2 may have some connection with the new 

 policy regarding tuition fees for extra courses. The chief assist- 

 ant in this course was Mr. A. M. Banta, the sub-assistants being 

 Messrs. E. D. Congdon, H. S. Davis, and R. C. Mullenix. Mr. 

 M. Copeland was laboratory assistant for the course in Radcliffe 

 College. 



The number of students in Zoology 3, under Dr. Rand, was pre- 

 cisely the same as in 1905-1906, but of these one completed the 

 work of the first half-year only, and another was a special student 

 of maturity who did the work of the first half-year without taking 

 examinations or receiving credit. The regular assistant, in the 

 laboratory was Mr. C. 0. Esterly, and Mr. J. A. Long also gave 

 some time to assisting in this course. There were two students 

 in the Radcliffe course and no assistant in the laboratory. 



There were only slight changes in Zoology 4, the course being 

 carried on by Professor Mark and Dr. Rand, as in previous years. 

 In accordance with the plan adopted when Zoology 6 was an- 

 nounced, the lectures in Zoology 5 dealt with the broad outlines 

 of vertebrate development, the subject of organogeny being re- 

 served for the alternating course (Zoology 6). As usual, in the 

 lectures most attention was given to the parts least readily mas- 

 tered from text-book reading, and to the discussion of special ques- 

 tions. The laboratory work, as hitherto, was conducted by Dr. 

 Rand, and was largely devoted to a study of the early stages of 

 the chick. In one particular it was modified from that of former 

 years ; previous to the study of incubated hens' eggs considerable 

 time was given to a study of the ovary of the Guinea-pig, and to 

 an examination of the unincubated hens' eggs — both sections 

 and dissections.
