LECTURE XXVII. 
Epidemic Catarrhf and Malignant Catarrhal Epidemic in Cattle 
—Bronchitis in Horses and Cattle~The peculiar Bronchitis 
in young Cattle, accompanied bij Worms in the Bronchial 
Passages. 
EPIDEMIC catarrh is a more frequent and more destructive 
disease in cattle than in the horse. In a cold yet variable spring, 
succeeding to a wet and mild winter, there will sometimes be 
scarcely a dairy or a stall-yard in which a considerable number 
of the cows do not labour under the most distressing hoose, and 
in which few are altogether without cough. This, how^ever, is only 
the early or most prevalent symptom. Costiveness is also ob¬ 
served, on which your castor oil or Epsom salts, although given 
in repeated doses, will make no impression; and then, all at 
once, diarrhoea will come on, which bids equal defiance to your 
astringent drinks. In many cases diarrhoea is present and 
obstinate from the beginning. Tumours about the joints, the 
neck, the roots of the ears, the head generally, the back and the 
loins, soon succeed; at first apparently caused by the extrication 
of gas in the cellular membrane, and recognized by a singular 
crackling sound when pressed upon. It would appear as if the 
process of decomposition was going forward during the life of 
the animal. No sooner do these tumours appear, than the faecal 
discharge is offensive in a high degree ; the breath loses its pe¬ 
culiar and beautiful scent; the vital powders are rapidly exhaust¬ 
ing ; the powders of the organic system first, and soon afterwards 
of the locomotive, and the animal system generally. The beast 
is unwilling to move; it can scarcely move—it staggers as it 
walks. The loss of flesh can now be traced every day : the coat 
stares, and clings to the carcass ; the appetite has been long since 
gone ; a fetid discharge commences from the mouth and nostrils, 
and the end is not far off.
