The aphthous epizootic of cattle has caused little mortality, but 
considerable loss has been experienced from the diminution or 
suppression of their milk, or the state of emaciation to which they 
have been reduced. Although its causes are little known, its 
duration and its return are attributable to frequent changes of 
temperature, or to the hygrometric state of the atmosphere. The 
treatment depends on the peculiar character which the dis- 
ease assumes. Whenever a decided adynamic character was 
present the employment of the mild vegetable tonics was clearly 
indicated. 
The distemper of dogs has been more than usually prevalent, 
and a great number have perished from the determination of the 
inflammation to the lungs or the pleura. The nervous or rheu- 
matic affections to which they are occasionally subject have been 
less frequent, which is probably to be attributed to the uniformity 
of temperature that has prevailed. For the same reason, rabies 
has not been prevalent. 
Towards the end of the winter and the commencement of spring, 
and produced by the sudden and precocious increase of atmospheric 
temperature, a disease prevailed among the market cart-horses, 
and those that were employed in lighter agricultural labours, or 
that were driven to the different markets for the purpose of sale, 
characterized by intense gastric fever, loss of appetite and strength, 
constipation, determination of blood to the head, and giving to 
the patient a strange straggling gait. The pulse was full — the 
respiration embarrassed — the vessels of the conjunctiva injected 
— the eyelids swelled, and even the body of the eye participating 
in the inflammation. 
After a few days a deposit of lymph or of blood took place in 
the anterior chamber of the eye. The skin and the exterior 
mucous membrane were also of a yellow hue. 
Our first indication of cure was to combat the cerebral conges- 
tion, and the inflammation of the eyes by general bleeding and 
the application of local refrigerants. The second indication was 
to abate the disturbance of the stomach by the employment of 
barley-water acidulated with vinegar, or with nitre dissolved in 
it, and also to make use of frequent injections. The tension of 
the abdomen, the colicky pains and the tumefaction of the region 
of the liver, required emollient and anodyne applications. The 
continuance of the congestion of the brain, or eyes, or abdomen, 
indicated the necessity of further abstraction of blood, but less 
general, less copious, and confined to the vessels of the face, or 
palate, or external thoracic vein, or one of the saphenas. Then 
also, if the internal membranes of the eye had become the seat 
of a morbid secretion, setons were placed in the poll ; or, if
