part of the course; and it holds the attention of the class com- 

 pletely even past the official end of laboratory work. 



No attempt is madie to put the entire class through a fixed 

 schedule of laboratory work ; even where everyone is working on 

 the same material, as much as possible of the method of attack 

 and particularly of the method of recording observations is left 

 to the individual. Students who desire space in the laboratory 

 and access to laboratory material but who have their own plan 

 of work they desire to follow, are welcome as a matter of course. 



Field Work. The field work is one of the most important 

 aspects of the entire course ; even the anatomy cannot be clearly 

 understood until the animal has been seen in its native haunts. 

 Gross collecting methods are avoided as far as possible and the 

 student is urged to observe carefully while collecting where the 

 animals are found and what they are doing.
