HYPODERMIC MEDICATION AND ITS APPLICABILITY IN EQUINE 
PRACTICE. 
By J. Roberts Nayler, D.V.S., Ph.G., Jersey City, N. J. 
Having long felt the necessity in equine therapeutics for a 
better method of administering medicaments to our patients than 
the common mode recognized by practitioners of all grades, it 
occurred to me recently to try the hypodermic method, for two 
important reasons, viz: 1st. On account of its easy administra¬ 
tion ; 2d. Because quick results can be obtained, and that with 
the least minimum of annoyance to the practitioner. Take, for 
instance, the removal of a serous cyst, which sometimes, with a 
fractious animal, gives the operator a great deal of trouble, which¬ 
ever way he chooses to undertake its removal, whether by sur¬ 
gical operation, seton, or the insertion of hydrargyrum bichlori- 
dum and acid arsenicum, or even the ligature to which many re¬ 
sort in order to effect its removal. 
Instead of any of the foregoing methods, it has been my plan 
of late to insert, hypodermically, acid, carbolicum; and since re¬ 
sorting to this procedure, I have met witli much less annoyance 
(and in each instance with complete success) than with any of the 
means above enumerated. I usually inject the acid carbolicum 
in a solution containing 10 per cent. ; in some cases I have even 
used the pure acid, and in no single instance have I met with any 
but good results. 
In rheumatoid affections of the joints, when it seems extreme¬ 
ly painful for the animal to move, brilliant results often ensue 
from a 2 to 5 per cent, solution of acid carbolicum, hypodermic¬ 
ally inserted as near the seat of the pain as it is possible to locate 
the same. Partial anaesthesia ensues in a few minutes, and our 
patient seems relieved of the pain. 
In simple colic, the hypodermic injection of morphia acetatis 
has in my hands been the means of giving prompt relief, especi¬ 
ally when combined with gelsemin. 
I have also found the administration of pilocarpin, hypoder¬ 
mically, in pneumonia (when iio indication of any weakness of
