A LIST OF FLUID EXTRACTS, 



8EOENTLY INTRODUCED INTO VETERINARY PRACTIO* 



By G. H. DADD, V. S., 



WITH INSTRUCTION REGARDING THEIR ACTION, AND 

 THE QUANTITY TO BE ADMINISTERED. 



THE introduction of medicines, in the form of Fijjid Ex- 

 tracts, for the treatment of diseases incidental to domestio 

 animals is considered a very great improvement over the old 

 method of drenching by the pint or quart, to the great disgust of 

 the patient as well as the practitioner, and the great danger attend- 

 ing the administration of a large quanty of fluid which was neces- 

 sary when crude materials were used. In the use of fluid extracts 

 all danger is obviated and much labor saved, for the doses are 

 quite small, rarely exceeding one fluid ounce. This can be merely 

 placed on the tongue, the animal's head being slightly elevated, 

 and he swallows it without any difficulty or resistance. 



The fluid extracts bear an exact relation to the crude materials— 

 that is, ounce for ounce — yet, from a variety of circumstances, they 

 may vaiy slightly from this standard. It is, however, the inten- 

 tion of the manufacturer to completely exhaust the active principle 

 of the crude material and render the medicine uniform in strength. 

 The fluid extracts used by the author are manufactured by Messrs. 

 Garrison & Co., manufacturing chemists, of Chicago. They con- 

 duct their evaporations at a very low temperature, by means of an 

 improved steam bath, and use only select drugs, thereby prevent- 

 ing the possibility of adulteration. I have used large quantities 

 of medicine manufactured by the above-named firm, and find them
