GENERAL DIRECTIONS 



It is desirable that the physiologic work should be corre- 

 lated so far as possible, /. e. the lectures, recitations and lab- 

 oratory work should be given during the same term and have 

 as close connection with each other as possible. If this is not 

 practicable then the recitations or lectures should precede the 

 work in the laboratory. 



Quizzes on the work gone over may be regarded as a part 

 of the laboratory course and should occur at frequent intervals. 



Notes should be taken on the experiments as soon as they 

 are performed. The manual is intended as a laboratory com- 

 panion and the blank pages are provided for this purpose. 

 Note taking is a portion of the laboratory work and the notes 

 are to be submitted to the instructors for correction. 



Unexcused absences, tardiness in beginning the work and 

 leaving without permission before the end of the period will 

 be noted, and the mark or standing of those concerned will be 

 correspondingly reduced at the end of the term. 



Many of the reagents which are to be frequently used will 

 be placed on the student's desk on or before the periods in 

 which they are needed, other reagents less frequently used, 

 will be placed on the general shelves and the student must not 

 carry these general reagents to his desk. 



Any special reagent or apparatus, not included in the 

 at)ove, may be obtained when needed, by handing an order for 

 it to one of the assistants. 



Before beginning his experiments, the student should 

 inventory his locker and check ofE on the slip, furnished for 

 the purpose, each piece of apparatus that is designated. The 

 slip is then signed by the student and is held by the depart- 

 ment as a receipt. At the end of the term the contents of 

 each locker are examined and compared with the receipt. 

 Any articles that are missing, broken or damaged are charged 

 to the student. 



Where there is any doubt as to the result of the experi- 

 ment or any indefiniteness in the reaction consult with the 

 assistant before taking up a new experiment.
