an ulcer on the free border of the epiglottis, and an osseous degene- 
ration of the anterior beak of the cricoid cartilage, and of the kind 
of crest which the two arytenoids form before the attachment of 
the epiglottis. The lungs of all three were tuberculous. We may 
conclude, from these facts, that the horse as well as the human 
being is subject to laryngeal phthisis. 
Bronchitis. — A great many horses and dogs were attacked 
by this disease in the spring and the commencement of the sum- 
mer; and it was not a simple affection, as when the seasons are 
tolerably regular. It was complicated with coryza, and engorge- 
ments of the submaxillary glands, and phlegmonous tumours of 
the parotid glands, and angina. 
The disease was successfully treated by the ordinary means 
if the proprietors took care of their horses during the period 
of convalescence. When, however, they made them work too 
soon, or exposed them to the wind and rain, and when the dogs 
were suffered to go into the water, bronchitis soon changed to 
pneumonia or pleuro-pneumonia, and most of the animals died. 
Those that were saved were never afterwards perfectly sound in 
their wind. 
In the treatment of these maladies, and of pleurisy generally, 
we have derived much advantage from repeated small bleedings, 
as long as the pulse was hard and the respiration laborious. 
We have preferred setons in the chest, and the application of 
cataplasms of linseed meal and mustard under the chest, and 
scarification of the engorgement that was the result, rather than 
vesicatories, which in these cases are often attended by the incon- 
venience of irritating the stomach and producing strangury. 
Out of 51 cases of bronchitis, we succeeded in saving 46. 
Mucous Fever. — We had occasion to see from time to time 
a species of mucous fever prevailing among horses from the 
latter part of the autumn to the beginning of spring. As summer 
approached, a new character and a yellow tint shewed that it had 
degenerated into bilious fever. It w ; as not, as in seasons when 
much moisture prevails and continues, accompanied by cedema- 
tous swellings of the limbs aud under the belly, but by a soreness 
of the throat, even from the commencement of the trachea — a 
slight cough — a bronchial rale — a heaving of the flanks — 
a clammy state of the mouth — an absence of all muscular 
energy — a diminution of the temperature of the skin — a dis- 
turbance of the pulse without acceleration of the circulation or 
of the breathing — this was the series of symptoms that charac- 
terized the disease. It terminated happily in the greater number 
of animals after a duration varying from eight to thirty days, or 
more. The horses that died had from the beginning lost their
