tures, or faschia of muscles, and the inter-articular cartilages of 
the joints, and, finally, the articulating surfaces of the bones Se 
come involved. The disease is always characterized by grea 
pain, and sometimes swelling in the re 
gion of joint. It is accompanied by 1 
. quick and wiry pulse, and by other symp- 
toms, denominated febrile. It occurs 
among men and horses at all seasons 
of the year, yet at the period of sud- 
den transitions from heat to cold it is 
most prevalent. Animals when heated 
by exercise, and then suffered to “cool 
off,” without ordinary care, are very apt 
to become the subjects of this malady, so 
that prevention, to a certain extent, is 
within our power, and, in the exercise 
of preventive measures, we may, n com- 
mon parlance, “stave off,” for a time, 
this disease, although it may be latent in 
the system as an hereditary affection. 
agTUENAL Muscire ax Texooss Mr. i’, Dun, who is good authority on 
the subject, says: 
“Rheumatism is neither so common, nor are its symptoms so 
well marked, in horses as in cattle. When, however, it does occur 
in the horse, it manifests the same well-known appearances which 
characterize it in all animals. It affects the fibrous tissues of 
joints, the coverings of muscles, tendons, valves about the heart, 
and larger vessels, and manifests a peculiar tendency to shift from 
one part of the body to another, often affecting, in succession, all 
the larger joints—at one time chiefly in the neck, at another, in 
the back and loins, while, in many of its more acute attacks, it 
appears to involve almost every portion of fibrous and fibro-serous 
tissues throughout the body. In all its varied types it exhibits a 
fall, strong, hard, and unyielding pulse, caused by the inflamma- 
tion involving the serous and fibro-serous tissues of the heart and 
circulating vessels. During its existence, various excrementitious 
matters accumulate in the blood, and the fibrinous constituents 
of the same exceed their normal proportions, as indicated by the 
production of the buffy coat on the blood. In severe or badly- 
treated cases, the inflammation is very apt to be transformed from
