ON THE INFLUENZA IN HORSES. 
only two deaths, both of which were old animals, and, for a long 
time previously, they had shewn very marked symptoms of decay. 
One was an old pony, the property of J. Crowther, Esq., of 
Newtown Mills, near Huddersfield. The animal was seized first 
with the oedematic state. Bleeding and the other remedies which I 
have mentioned were resorted to, and the animal at one time ap- 
peared recovering. The oedema of the body and extremities gra- 
dually disappeared ; when the nervous state suddenly supervened, 
and, in spite of every effort, death took place six days afterwards. 
Examination twenty-four hours after death . — Inflammation had 
extended throughout the whole of the intestines, particularly the 
large ones. They were of a dark (nearly black) brown. The sides 
of the diaphragm, the pleura, and the surface of the lungs, were of 
a grass-green colour. The surface of the lungs was corrugated, or 
shrivelled — much flattened, and apparently diminished to about 
half their natural size. On cutting into their substance, some por- 
tions were hepatized, while others were like a sponge, filled with 
black blood, and a frothy fluid of strong tenacity. The bronchial 
tubes (particularly one) appeared much enlarged, and gangrenous 
throughout. In about an hour, when thrown upon a heap, they 
appeared a putrid mass, devoid of form and elasticity. The heart 
was very large, much softened in texture, and pale in colour. The 
liver was sound, at least sounder than any other part I examined. 
From the morbid appearance of the intestines, the animal must 
have suffered acutely ; yet it is, perhaps, worthy of remark that no 
symptoms to that effect were shewn when alive. 
The second which died was an aged draught horse, belonging to 
Messrs. Carver, Driver, and Co., carriers of this town. The dis- 
ease, or rather diseases in this case, were nervous influenza, com- 
bined with inflammation on the lungs. The animal was taken ill 
on the 2d of January last, and continued to get gradually worse 
until the 6th, when he dropped and died, almost without a struggle. 
Fourteen hours after death the following appearances were pre- 
sented : — The intestines were of a dull brown colour throughout, 
very dry, and shrunk in size. The liver exhibited no marks of 
disease. The lungs were of full size, but much higher in colour 
than natural. The middle of the near lung was hepatized, which 
plainly pointed out the seat of the inflammation. When cutting 
into their substance, a frothy colourless fluid flowed copiously on 
withdrawing the knife. The frothy fluid existed likewise in great 
quantities in the bronchial tubes, many of the smaller ones in 
particular, being completely choaked up. The lower part of the 
trachea (for about half its length) was internally of a deep red 
colour. The pleura, the liver, and the heart, appeared sound. 
Inflammation in this case was evidently in its first and second
