PLAN FOR USING LABORATORY STUDIES OF 

 TYPIC ANIMALS 



The authors have found by experience that the following 

 order of studies is a good plan for each type: 

 Study of the Live Animal. 



I. General Preliminary Study. The student should learn 

 to take such points as he can answer from the animal, omit- 

 ting only such as do not apply to the animal under considera- 

 tion. "Ask the animal, do not ask the teacher." 



II. Ecologic or Environment Study. All points which 

 apply to the animal under consideration, numbering your 

 answers accordingly. 



III. Study of Animal Behavior. 



IV. Special Morphophysiologic Study. 



V. Systematic Study of the branch, class, and order to 

 which the animal belongs. 



VL Final Study, which should be preceded by the study of 

 the descriptive text. 



These studies give the student a formula to follow in study- 

 ing animals from different viewpoints, and fix the facts and 

 principles in his mind. 



Each teacher w\\\ observe that the Studies I, II, and III do 

 not require dissection, but are intended to give the student a 

 preliminary view of the live animal, if possible, but in any 

 case, with the animal before the student. Then follows the 

 Morphophysiologic Study, or the dissection, for which a 

 separate study is provided for each animal type.
