When cough exists, which is not always the case, at first it 
is dry, after some time it becomes less so from the exudation 
which is taking place in the pulmonic structures. Foetor of the 
breath denotes that gangrene and disintegration of lung tissue 
has occurred. During the height of the fever the urinary secre¬ 
tion is lessened in amount and altered in composition. There 
is excess of urea, caused by active tissue-change ; there is a 
diminution of the salines, more particularly of the chloride of 
sodium. We have some physical signs that are deserving of 
careful observation and study, seeing that, apart from the assist¬ 
ance which they render us, in the differing changes of structure, 
might pass unappreciated. The sounds detected by ausculta¬ 
tion, and elicited by percussion, are both of them in inflamma¬ 
tion of the lung substance much modified. In the early stage 
of arterial irritation, auscultation is increased, with harsh respi¬ 
ratory murmur. This symptom is often followed by a weaken¬ 
ing of the normal sound : when effusion takes place, the respira- 
O ' % 
tory murmur is replaced by the true crepitant rale. Seeing that 
in pneumonia inflammation we do not often obtain anything 
more definite than a slight amount of dullness, or want of 
resonance even from other symptoms, we are very certain that 
the pulmonary tissue is much diseased. 
Treatment .—The first thing to do is to pay strict attention 
to hygiene ; abundance of fresh air is indispensable. The body 
should be clothed according to the season of the year, the limbs 
bandaged ; it is well to envelop them in cotton batting before 
putting the bandages on. Feed anything that the animal will 
eat, but be sure and let the animal have all the fluids it will 
take ; keep strength up by giving milk, beef tea, and such 
things. Tet the animal inhale pure iodine vapor four or five 
times a day. My medical treatment is as follows : Whisky or 
good French brandy from the first, in dozes of 4 oz. (according 
to the size of the animal), three times a day, and once or twice 
during the night, with carbonate of ammonia, and also quinine 
electuaries. I do not use any counter-irritants, but have the 
animal’s lungs bound around with hot cotton batting. I have
