Then as to the danger, there is no comparison 

 between the two. I have only once had any 

 bad results from the use of cocaine ; but with 

 chloroform, sometimes, in spite of every care 

 and precaution, the dog will, when under its 

 influence, suddenly collapse. Besides, when a 

 dog, in a case such as I have just described, 

 struggles very much against receiving the chloro- 

 form, it takes longer to get him under the 

 influence of the drug than one taking it quietly ; 

 and then, often as a consequence, the dog at 

 last becomes exhausted, and if the chloroform 

 is persevered with, it takes too strong effect — 

 the heart's action becomes weak, the breathing 

 heavy, and collapse may occur — the result is, 

 one is obliged to leave off the operation to 

 administer restoratives to save the patient's life. 



In many operations, as the excising of tumours 

 (even large ones, weighing six or seven pounds), 

 removing thorns from the eye, sewing and 

 dressing painful wounds, cocaine is equal to 

 chloroform in its effects, for it completely deadens 

 for a time the parts to which it is applied, though 

 the animal retains complete consciousness. 



It is particularly valuable when removing 

 mammary growths, so frequently seen in bitches. 

 On many occasions I have removed a growth of 

 this kind weighing, in some instances, seven to 

 eight pounds, without subjecting the dog to the 

 least pain ; and I may here remark that the 

 application of cocaine does not in any way retard 

 the healing process. 



Cocaine for most purposes is best used dis-
