ls in this class of patients, have reason to conclude that they are
more liable to it than the female.

"About twelve months ago, I examined the head of a cow, on the right
facial region of which there existed an enormous tumor, extending from
the eye to the lips, and which I mistook during life for a periosteal
enlargement. On cutting into it, my mistake was evident. There was
scarcely a trace of the original bones beneath the mass; even those
forming the nasal sinuses on that side were replaced by a formation much
resembling the cysts before alluded to, and full of abscesses. The
progress of the disease was decisively marked in the inferior rim of the
orbital cavity, where the osseous matter was being removed, and the
morbid structure deposited."

ULCERS ABOUT THE JOINTS.

Occasionally, the joints assume a tumefied appearance, generally
ulcerating, and causing painful wounds.

_Treatment._--The application of one part of alum to two parts of
prepared chalk, powdered and sprinkled upon the parts, is usually all
that is required.

WARBLES.

It has been a prevalent opinion among farmers, that warbles are so many
evidences of the good condition of their cattle. It must, however, be
borne in mind that the warbles are the _larvae_ of the _oestrus bovis_,
which is said to be the most beautiful variety of gad-fly. This fly,
judging from the objects of its attack, must be particularly choice in
its selection of animals upon which to deposit its eggs, as it rarely
chooses those poor in flesh, or in an unhealthy condition. From this
circumstance, probably, has arisen the opinion above-mentioned.

[Illustration: HOME AGAIN.]

These warbles--or _larvae_ of the _oestrus bovis_--so nearly resemble
bots in the horse--or _larvae oestrus equi_--that, were it not for
their increased size, they might readily be mistaken the one for the
other. There is, however, one other difference, and that is in the rings
which encircle the body; those of the former being perfectly smooth,
while those of the latter are prickly, and from one third to one half
smaller.

The author was called, in the year 1856, to see the prize cow, Pet,
belonging to James Kelly, of Cleveland, Ohio, whose extraordinary yield
of butter and milk had been reported in the _Ohio Farmer_, a short time
previous to his visit. This animal was found by him in rather poor
condition; the causes of which he could only trace to the existence of
these worms, comfortably
