620 ON THE PRESENT EPIZOOTIC AMONG CATTLE. 
at once wholly arrested, and which not unfrequently happens 
before the appetite is materially impaired. If the animal is now 
examined, there is heaving of the flanks ; quick, but regular, 
breathing, and not spasmodic or catching. There is also cough, 
with a peculiar hoarse sound, better understood by the ear than 
described by the pen. This, at least, tells of inflammation in the 
larynx and larger bronchial tubes. 
There is some soreness of the throat, and a continual drivelling 
of saliva from the mouth. Ere long, costiveness is sufficiently 
manifest, and the little dung that is voided is thickly coated 
with mucus. It is not improbable that that inflammation which 
occasioned this extra secretion of mucus in the digestive canal, 
may become so extensive as to so change both the quantity and 
quality of the secretion, so that, instead of affording protection, 
it may become an abundant source of irritation, and thus esta- 
blish superpurgation. Not unfrequently, symptoms of laryngitis, 
bronchitis, pneumonitis, and pleuritis, follow each other in regu- 
lar and, sometimes, rapid succession, accompanied by symptoms 
of gastric affection. I will subjoin a case or two, exhibiting the 
symptoms and my treatment of it. And, after this, I am not 
certain that, at some future time, I may not advert to this subject 
again. 
Case I. — June 12, 1843. This morning I was requested to see a 
three-year-old heifer, and found her labouring under the following 
symptoms : — The breathing quick, but regular ; the pulse about 
60, and bounding ; the whole of the eye presenting a hue of red ; 
the mouth hot ; the extremities colder than natural ; the coat 
staring ; frequent cough ; protrusion of the muzzle ; she eats 
and drinks carelessly, and chiefly in a standing posture ; dungs 
little, and the fseces are harder than they ought to be. She had 
been seen to be a little out of health the day before. I bled her 
freely, and ordered a dose of salts to be given with a little ginger 
in gruel. 
After this, she had a compound like the following given twice 
a-day until she was so far restored as to be dismissed : — R. Pulv. 
digital. 3ss, antim. and potass.-tart. 3j, pulv. potas. nit. 3 iij, 
sp. seth. nit. 3iv. M. At its first outbreak in this neighbourhood, 
1 treated a number of cases in a way similar to the above, only 
adding, occasionally, some local remedies, such as blistering, se- 
toning, &c. ; but did not save more than two-thirds of my patients. 
This great mortality induced me to look out for other remedies. 
Case II. — August 6th, 1843. An aged cow. The pulse about 
70, weak, and tremulous — the breathing quick and stitchy — a 
short, frequent hoose, with a grating sound — the nose extended 
— a collection of froth about the outside of the lips- — the tongue
