tying it as securely as possible with a surgeon’s knot. The 
dissected nerve-trunk is cut above the ligature and the silk is 
allowed to hang out of the lower part of the incision to the 
length of about one inch. No stitches being used, a cotton 
bandage, saturated with a solution of bichloride of mercury 
is applied to the fetlock, which draws firmly together the 
edges of the incision. Over this is again laid an antiseptic 
■flannel bandage. Within three days after the operation the 
bandages are removed, when the wound will be found to 
have united by first intention, with the exception of the lower 
end, out of which the ligature is now carefully and easily 
removed. When the ligature comes off, the nerve-end is cic¬ 
atrized, a granulating process is obviated, and the union of 
the nerve-ends thus made impossible. The parts are dressed 
and the bandages replaced in order to support the newly 
united tissues. Shower baths for a few days have been found 
of good service, and in from five to ten days the horse is again 
ready for work—a result which can hardly be obtained by 
the old methods. 
Of about one hundred horses so operated upon by me since 
February last, no report has been made so far of an unsatis- 
jl factory result, and all those cases which could be kept under 
observation have proved a decided success, not only from a 
surgical view, but also from the practical results obtained.

EFFECTS OF THE TOXINE. 
As we have said before, the microbes of hog cholera and of 
swine plague are killed by being kept a certain length of time 
to a temperature of 58°. To this effect I heated the culture 
or the blood received in a glass tube closed at both ends, with 
the alcoholic lamp, in a water bath kept at an even constant 
temperature.
