Rheumatism.—This disease owes its origin to the 
state of the blood as the result of impaired digestion and 
assimilation: it is charged with elements inimical to its 
constitution, an arrest of certain functions being the 
cause of their accumulation and retention within the 
organism. The disease exhibits a preference for particular 
tissue, such as the joints and ligaments, when it is known 
as articular rheumatism; and in the muscles, especially 
their terminations and attachments by tendons. The 
latter form producing much stiffness of the body, 
especially, has been known for generations as the ‘‘chest- 
founder” of the old farriers, and lumbago of more recent 
days. In sporting dogs the disease appears as the result 
of cold and damp quarters, hence the term “ kennel- 
lameness.” 
Two forms are observed, the acute and chronic, the 
first, as a rule, subsiding into the latter, assuming per- 
sistent and incurable states, extremely liable to aggrava- 
tion by adverse states of the temperature and moisture 
of the air. The acute form is also liable to become 
periodic, and heart complications, as valvular disease, 
of a serious and fatal nature are common. 
Symptoms.—In the acute articular form the joints are 
hot, swollen, and intensely painful. Movement causes 
intense agony, which the sufferer avoids, but yelps 
piteously when forced to change his position. 
In the muscular form or “ chest-founder,” the sufferer 
is more or less unable to advance the forelegs, or move 
the shoulders, which are stiff, the whole of the limbs 
being carried in a piece, and with extreme care. The 
sufferer objects to being handled, and yells loudly when 
the limbs are manipulated, especially if abducted or 
moved away from the body. Considerable fever is 
present. 
In lumbar rheumatism the same objection to move- 
ment is evident. The back is arched upwards, the feet 
being near together, movement in any direction causing 
intense agony, and as a result, the creature refuses to be
