152 Specific and Contagious Diseases. 
with dirty-looking mucus. Shortly the throat is inflamed 
and sore, outward pressure causing pain and coughing, 
the urine scanty and highly coloured, bowels constipated, 
legs and ears cold, and appetite very capricious, any 
attempt to swallow provoking vomition. In mild cases 
these signs prevail some days, and the patient may 
recover, or the change may be in the development of 
severe complications, often ending in some incurable 
form of disease, or death within a few days. 
There are also conditions which merge from the simple 
catarrh at the outset, which we must now notice. The 
disease may appear to be mainly located in the nose, 
eyes, &c. The discharges grow exceedingly thick and 
tenacious, accumulating around the eyelids, on the face 
below, and about the nostrils and lips. The eyelids are 
closed and even united by the hardened discharge, and 
the breathing is impeded by similar accumulations in the 
nostrils, relief in either case being gained - only by care- 
ful soaking with warm water, and removal of the en- 
crustations. Blood circulation and supply are deficient, 
the result of which is that the parts affected are not 
nourished; the discharges are offensive, and contain 
blood, the result of ulceration, which appears in the form 
of numerous sores on the nostrils, lips, and even the 
gums, tongue, &c. The eyes are likewise involved, 
opaque spots first appearing on the eyeballs, and by sub- 
sequent ulceration or abscess, perforate the tissues and 
the aqueous humour escapes. In those cases which 
recover, the process of repair is wonderfully rapid and 
effective, the eye being ultimately clear and sight unim- 
paired. Similar results are not uncommon with respect 
to the general state of disease. The animal is fearfully 
prostrated, and each day is thought to be his last. A 
few hours decides the issue of the case, and he suddenly 
pulls himself together, enters on the path to recovery, 
and in a few days is convalescent. In other cases, and 
in the earlier stages, improvement is suddenly apparent 
by the absence of all the severe symptoms ; shortly, how- 
ever, he appears weak in the back, is unusually excitable, 
and at length the worst that can befall him is seen in the
