EXPERIMENTAL PHARMACOLOGY 



PART I. 



PRELIMINARY EXERCISE. 



Assignment of Tables and Permanent Apparatus. 



At a time previous to the first laboratory meeting if pos- 

 sible the students will arrange themselves according to 

 instructions into groups of four or five each. It is gener- 

 ally desirable (especially if the students are unknown to 

 the instructor) for the students to arrange these groups 

 themselves. This should usually be done Avith due con- 

 sideration of the relative degree of progress and of 

 ability which each student possesses, students of approxi- 

 mately equal standing being grouped together. 



This is a matter of considerable importance to the 

 student, for no one cares to drag a poor student through 

 several weeks of difficult experimentation, while on the 

 other hand the poorer students should not be cheated out 

 of their opportunities to learn because other more compe- 

 tent students do all of the work. The average of the grades 

 which the students have received in previous courses is 

 usually a fair basis for forming these groups. 



For mammalian experiments students work in the groups 

 of four or five (rarely three or six under special condi- 

 tions). Each group of four (or five) is subdivided into 

 sub-groups of two (or two and three) for work on frogs, 

 turtles, etc. 



Each group of students will be assigned to a table (or 

 locker) in which the permanent apparatus of the group is 

 already placed and is in perfect working condition. This
