le. This swelling is hot and
painful to the touch, and renders the animal stiff and lame. On pressure
with the finger the swelling can be indented, but the pits so formed
soon fill again on removal of the pressure. In severe cases we may have
ulceration of the skin, and serum pours out from the surface, resembling
the oozing which we have after a blister or in a case of grease. This
swelling is not to be confounded with the stocking in lymphatic horses
or the edema which we have in chronic heart or in kidney trouble, as in
the last the swelling is cool, not painful, and the pitting on pressure
remains for some time after the latter is withdrawn. It is not to be
confounded with greasy heels. In these the disease commences in the
neighborhood of the pastern and gradually extends up the leg, rarely
passing beyond the neighborhood of the hock. The swollen leg in
glanders almost invariably swells for the entire length in a single
night or within a very short period. When greasy heels are complicated
by lymphangitis we have a condition very much resembling that of farcy.
The swelled leg in farcy is frequently followed by an outbreak of farcy
buttons and ulcers over its surface. In the entire horse the testicles
are frequently swollen and hot and sensitive to the touch, but they have
no tendency to suppuration. The acute inflammation is rapidly followed
by the specific induration, which corresponds to the local lesions in
other parts of the body.

Chronic farcy in the ass and mule is an excessively rare condition, but
sometimes occurs.

CHRONIC GLANDERS.

_Symptoms._--In chronic glanders we find the same train of inflammatory
phenomena, varying in appearance from those of chronic farcy only by the
difference of the tissues in which they are situated. In chronic
glanders there is first the nodule, from the size of a shot to that of a
small pea, which forms in the mucous membranes of the respiratory tract.
This may be just inside the wings of the nostrils or on the septum which
divides the one nasal cavity from the other, and may be easily detected,
or it may be higher in the nasal cavities on the turbinated bones, or it
may form in the larnyx itself or on the surface of the trachea or deep
in the lungs.

The nodules, which are first red and hard and consist of new connective
tissue, soon soften and become yellow; the yellow spots break and we
have a small ulcer the size of the preceding nodule, which has a gray,
dirty bo
