contra :tion exist, the heels are to be opened, and the walls at the 
quarters must be rasped thin, so as to remove the lateral pressure 
on the sensitive parts. 
It may be necessary, in the event of the patient not being bene- 
fited by the above treatment, to reapply the counter-irritant ; this 
matter is left discretionary with those who take the case in hand. 
In the treatment of such cases, the owner of the afflicted animal 
must be prepared to exercise due patience, for the day of recovery 
may be far distant; often it is a mere question of time, and not 
one of skill. 
PLEURODYNIA (PAINFUL AFFECTION OF THE PLEURA AND 
MUSCLES OF THE CHEST). 
Pleurodynia (in human practice) signifies pain in the side, from 
a rheumatic affection of the pleura. In horses the malady not 
only affects the pleura, bur also the intercostal muscles. It is a 
very painful malady, and some persons are in the habit of calling 
it “founder.” Pleurodynia, however, differs in its origin from 
founder, inasmuch as the latter may arise from various cases, 
whereas pleurodynia is almost always the result of an excessive 
use of the muscular powers, or when the animal has been sub- 
jected to long-continued and very severe exertion. 
Symptons.—It will be noticed that the animal moves in a very 
stiff manner; steps short and quite slow—he appears about used 
up, as the saying is; the back is arched, and the skin is over the 
service of the bedy, and is not only hot but very tender; on mak- 
ing pressure over the regions of the sides of the chest, symptoms 
of pain will be elicited, showing conclusively that the intercostal 
muscles between the ribs and pleura, or lining membrane of the 
cavity of the chest, ave involved; the respirations are short und 
jerking, and the number of pulsations range from forty to sixty 
per minute. Both fore-feet are usually advanced, and, on apply- 
ing a hand to them, it will be found that they are unusually hot, 
and that they are inflamed ; the appetite is nct good; the urins 
is high-colored, and the bowels constipated. Such are the most 
observable and common symptoms of this painful malady, It is 
something like rheumatism in its pathology, and often migrates 
to the brain, or its investing membranes. When this happens 
there remains but little hope for the patient.
