far upwards in the cavity; sometimes parcels of the mem¬ 
brane hanging loose, being only partially detached; the car¬ 
tilage bare, necrosed, thin, of a dirty bluish-green color, and 
most often pierced through, opposite the nostrils, so as to 
cause communication between the two cavities. I am con¬ 
vinced, from my observation, that this destruction of carti¬ 
lage is not due to ulceration, but was caused by gangrene, 
due to want of nourishment after all the vessels were de¬ 
stroyed. All these sores are red, injected, with a rough, soft 
bottom, bleeding easily, with borders congested and tume¬ 
fied. The membrane of nasal wing is smooth, tumefied, shin¬ 
ing and often ecchymotic. Every day the sores are increasing 
in surface. Sometimes small spots will be noticed, greatly 
resembling a glandered ulcer, but upon closer examination 1 
could never detect any induration; nostrils are sometimes a 
little swollen; very seldom does the conjunctive membrane 
show any modification. Intermaxillary glands are soft, long 
or very large, painful, irregular, knotty on their surface, two 
or three glands existing at the same time. All are movable 
and free of any adherence with bone or skin. Respiration 
will be very laborious, wheezing on account of the oedema 
glottidis. 
During all this time the animals have a shining, lustrous 
coat, skin loose and hair smooth and glossy. They eat little 
and grow poorer from day to day, so that at the end of one 
month or so, if they are allowed to live, they become entirely 
emaciated. But some keep up a good appetite and remain 
in good condition for a long time, having a tolerably fair ap¬ 
pearance yet after five or six months. 
Post mortem examination .—The following is the correct 
description of the lesions found in the mule of David Kerr, 
near Modesto, killed August i, 1888, with a bullet in the head. 
An artery was struck, and death was caused from loss of 
blood, a large solid coagulum of black blood filling the tra¬ 
chea and bronchias. Lungs, liver, spleen and kidneys in a 
normal condition, perfectly sound. Bronchial ganglion 
lightly tumefied, two intermaxillary glands swollen, soft, 
loose, resembling a lymphatic vessel duplicated, full of coag-
