PHARMACOLOGY. 



THIS section has been written for the purpose of presenting the leading data of 

 Pharmacology in a compact, concise form. In the average text-book on any subject, the 

 essential facts are not infrequently submerged in a sea of speculation, discussion, and 

 rehearsal of evidence, all of which has its great value, especially for the weighing of 

 mooted points ; but there are also times when the immediate determining of the essen- 

 tial fact is more important. For those times this section will prove valuable. 



This section is to be' used as an aid to one's work not as a substitute for that 

 work. It is not to be assumed that any earnest student would delude and cheat him- 

 self by presenting this data in lieu of that of his own delving. On the contrary, he will 

 use the information thus conveniently placed at hand for correctly orienting himself 

 when confronted with difficulties, or for adding to his sum of information. 



Readers of the literature of Pharmacology must be impressed by the lack of uni- 

 formity among writers concerning the pharmacodynamics of various drugs. Such dis- 

 agreements arise from the diversity of conditions surrounding the experimentation 

 with drugs, and therefore demand that in this science, as in all others, our conclusions 

 must be tentative only. In the meanwhile, we must pin our faith somewhere, selecting 

 such conclusions as seem warranted by the present weight of evidence. The faith of 

 this Manual is largely founded on "Cushny's Pharmacology," with such minor modifi- 

 cations as seem justified by personal experience.
