few hours afterward, be found stiff and lame. But the symptoms 
are not the same as those just recorded. The pathology is proba- 
vly identical ; it is the same disease, only it has a different locality. 
Nt is myositis of the pectoral muscles, involving, also, the muscles 
of the shoulder-blades, And the intelligent owner of the afflicted 
animal will notice that the fore extremities are unnaturally ad- 
vaxced ; the foreparts of the body are unnaturally hot and tender; 
the frre-feet are feverish, and the hoofs are hotter still. The ad- 
vanced position of the fore extremities and shoulders gives a very 
marked hollowness to the forepart of the chest, and many men, 
on seeing such a case, would declare that the animal was chest- 
foundered, this being the name which is sometimes given to such 
a condition ; but it is really owing to myalgia (muscular pain and 
stiffness). 
It is well-known that all muscles are subject to inflammatory 
action and muscular pain from work disproportionate to their 
strength. For example, let any man undertake to saw wood, 
practice with heavy dumb-bells, or ride on a horse—feats that he 
has never been accustomed to—and, whether the labor be excessive 
or not, the individual will shortly complain of more or less mus- 
cular pain; and if he be a weak man, the more excessive will be 
that pain. Now, the muscles of the horse, being just as suscepti- 
ble to pain as those of man, are just as easily operated on through 
the well-known exciting causes. 
Symptoms.—In the case of a horse, when the work has been ex- 
cessive, and of a character to bring the muscles of the shoulders, 
their tendons and coverings, into a state of over-exertion, it will 
often be found that some of the muscular fibers in the region of the 
shoulder are fractured, small blood-vessels are ruptured, and other 
pathological changes take place. This is followed by inflammation 
(myositis). Suppose, therefore, a horse shows symptoms of myo- 
sitis after excessive work, and, in the course of a few days, :t is 
noticed that the muscles of his shoulders are wasting away, and 
continue to waste, so that all persons who examine the animal 
pronounce him sweenied, we may then infer that the wasting 
(sweeny) is not symptomatic, but is the result of myositis. 
Treatment.—The principal treatment is rest ; afterward diminish 
the work, and, by proper diet and tonics, increase the power to de 
it. The muscular parts affected should be bathed, morning and 
evening, w:th a portion of the following:
