PRACTICAL USES OF COCAINE.

but in severing the cord with the ecraseur some degree of pain 
would be manifested. Injecting directly into the testicle pro¬ 
duced very little effect, if any, either on the scrotal walls or the 
cord. In two or three cases, where I could get at the parts, I 
made two injections—one in the scrotum and the other into the 
cord (with quite a long needle), just at or a little above the 
point of excision, and anaesthesia was complete all through 
the operation. This last method, however, cannot be made 
generally practical as the cord cannot be reached for the injec¬ 
tion sufficiently high up. Several dogs were castrated, and 
anaesthesia was complete simply from the injection into the 
scrotum, and I am fully convinced that this is a practical pro¬ 
cedure in all cases of castration. By it I had very little trouble 
in castrating aged horses without casting, or any other means, 
of restraint than the twitch. 
As a test in lameness, cocaine has not acted very satisfac¬ 
torily for me. In a few cases it has done well, but in many 
more I have been left in doubt after its use as much as before. 
I have been frequently called to cocaine joints, tendons, feet, 
etc., for a race, and in many instances the results have been 
very satisfactory, but in other cases it has taken such a quantity 
to obtain the desired results, and being absorbed, has produced: 
a general narcotic effect, making the animal unsteady in its 
work. To get the best results, the drug should be administered 
while the animal is quiet and free from excitement. This 
feature in the administration demands special attention, for 
good results are not apt to be obtained if the patient is under 
excitement when the agent is applied. In this way a small 
quantity will have its local influence without producing general 
effects. 
I have only seen one case in which the drug was used for a 
surgical operation that any general symptoms followed. In 
that one several injections were made around a large tumor_ 
probably 10 to 20 grains were used—and after twenty to thirty 
minutes the breathing became somewhat quickened and shallow, 
with general nervousness and staring appearance of the eye,
