PHARMACODYNAMICS. 



(Laboratory: Nine hours a week for one semester.} 



In this section of the Manual the student is expected to ascertain what physio- 

 logical reactions are produced by some of the more important and powerful of the 

 drugs he has been investigating heretofore in the other laboratory. He will work first 

 with simpler forms, gradually progressing to relatively more important presentations. 

 But at each stage his great purpose should be to discover exactly what departures 

 from the normal do take place. He must be ever on his guard not to read into his 

 observations any preconception, prejudice, or opinion. He must pay strict attention to 

 the work in hand, lest some important manifestation escape his observation. He must 

 consistently endeavor to perfect those cardinal faculties of careful observation, logical 

 deduction, and careful notation, on which depends much of his future success. 



Each student will be required to prepare himself concerning the technique of any 

 given procedure before being assigned full responsibility. The best available book on 

 this technique is "Jackson's Experimental Pharmacology"; an additional vadc mecum 

 is "Sollmann's Laboratory Guide." Leading texts in Pharmacology are Cushny and 

 Sollmann. Reference periodicals are: Journal of Pharmacology and Experimental 

 Therapeutics, Journal of Laboratory Medicine, Journal of Biological Chemistry, Jour- 

 nal of Physiology, American Journal of the Medical Sciences, Journal of the American 

 Medical Association.
