32 A XOTE TO THE STUDENT 



Each experiment in this book was designed primarily to 

 give the student an opportunity to learn to think, and sec- 

 ondarily to teach him some valuable point in connection 

 with the drugs studied. The writer fully appreciates that 

 there are certain difficulties and limitations beyond which 

 the average medical student can not go, and for the satis- 

 factory performance of the following experiments there 

 has been assumed a certain standard of attainment which 

 to the author's mind represents approximately that de- 

 gree of training which the average sophomore student at 

 the present time should have had when he takes up the 

 study of experimental pharmacology. The student will feel 

 constantly the necessity of drawing extensively upon his 

 knowledge of anatomy, neurology, and physiology, and 

 to a less extent upon his training in chemistry, physiolog- 

 ical chemistry, pathology, bacteriology, and physics. And 

 he must bear constantly in mind the practical clinical ap- 

 plication and action of the great majority of the drugs 

 with which he will experiment.
