JAMES LAW. 
A case of the same kind came under my notice in May, 1899. 
A11 aged, white, part-Arab mare, at Forest Home, had been ailing 
foi a day or two before I was called. I found her somewhat off 
her feed, but with a full brig'ht eye, alert motions, erect carriage 
of the head and ears, and only very slightly accelerated pulse and 
breathing. In short, she appeared a comparatively healthy horse 
011 cursory examination. The temperature, however, was 106, 
and the conjunctiva had a deep yellowish-red color approximating 
to what is usually seen in contagious pneumonia (brust-seuche). 
There was a slight cough, but no laryngeal tenderness, no dis¬ 
tinct crepitus in the lungs, no flatness on percussion, and only a 
slight exaggeration of the respiratory murmur. The high tem¬ 
perature in the absence of marked lung lesion, or dullness, and 
the yellow mucosa might have suggested brust-seuche or some 
other infectious disorder producing poisonous toxins. She was 
treated with acetanilid 2 drams, sodium salicylate 2^ drams, 
and potassium iodide 1 dram, given twice daily. 
There seemed to be little change for twenty-four hours, but 
suddenly on the second day, as reported by the owner, the 
breathing became increasingly difficult, and in a few hours and 
before I had been notified of the change for the worse, the pa¬ 
tient died. 
Necropsy was made the following morning in the open air, 
beside the giave, and revealed a generally petechiated condition 
of the tissues and especially of the serosae, where this contrasted 
strongly with the generally blanched appearance. There was a 
liquid pleural exudate of a dark red color, and the whole upper 
half of both lungs showed a deep, violet haemorrhagic conges¬ 
tion, resembling a dark bloodclot. Pleuritic fibroid thickening 
and adhesion indicated a former pleurisy from which the patient 
had recovered. On cutting into the congested portion of the 
lung it was found to be literally gorged, the blood dripping 
from the cut surface, and the mucosa and submucosa of the 
bronchia weie of a deep red hue and greatly thickened by extreme 
congestion. This remarkable congestion of the mucosa extended 
along the air passages so as to involve the larynx and pharynx.
