care and good food are the best restoratives. But, above all things, be

adhesion could take place, inflammation 
must have existed in the pleura, which lines 
the interior of the chest and envelops the 
lung itself; consequently, pleurisy must 
have been present before the pleura could 
be sufficiently inflamed for adhesion to en- 
sue. The other condition is the result of 
congestion ; the tubes and vessels alike are 
clogged, the lung is converted from its soft 
and spongy natural texture to a firm and

Now, in conclusion, we must answer the important inquiry,—what is 
the cause of this affliction? Poverty, without dependence, inherits few 
disorders. Nature, in mercy, spares the peasant those visitations which 
are heaped upon the nobleman. To what, then, shall we attribute the 
ailment of a life so entirely in possession of another as that of the horse ? 
Ts it untruth to point to that which in ordinary language passes for the 
master’s thoughtlessness? The creature is often worked, not to the 
point of fatigue, but is goaded to the possibility of exhaustion; fed 
upon the cheapest sustenance, and lodged according to the proprietor’s 
convenience; made subservient to the whims of vanity, and forced to 
conform to the habits or the caprices of fashion; now, waiting patiently 
in the storm; then, hurried along the dusty roads through the parching 
heat; now, stopped during a long journey and expected hastily to con- 
sume the provender which shall support life the remainder of the distance: 
treatment like this will provoke more acute evils than pneumonia. The 
last disorder is of too dull a type to be begotten by so harsh a parent. 
The horse which is pampered, or has much to eat and little work to 
do; the creature which for days may stagnate in the stable and then 
be suddenly brought forth to extraordinary exertion; the horse whose
