INFLAMMATION.

inflamed part will greatly reduce the pain by removing this 
pressure. 
The heat is due to increased chemical activity in the part, 
and this largely intensified, topical combustion causes the ac¬ 
celerated breathing of the patient to furnish the requisite amount 
of oxygen, just as threatened carbonic acid narcosis in the 
newly born foal or other young, by paralyzing the par vagum 
produces rapid respiration. 
Redness is a sequel, the increased flow of blood to the part 
and perhaps, also, to the extravasation of haemocytes. It at¬ 
tracts attention in our patients, chiefly where the skin is white 
and the hair short. 
Swelling and tension originate from infiltrated serum which 
permeates the adjoining portions and puts them on the stretch. 
Treatment. —For the sake of convenience, this section of 
the subject will be subdivided into two parts, constitutional and 
local. 
To dispel the hypermmia of the congestive stage of inflam¬ 
mation, belladonna, given internally, is the remedy par excel¬ 
lence, but we, more unfortunate in this respect than our cousins, 
the M. D’s, are often not called till too late to derive the great¬ 
est benefit from this most useful agent. Many times in fact the 
veterinarian is summoned so tardily that no system of therapeu¬ 
tics, however sound, would be of use, and nothing could restore 
the patient unless some one should be found, as of old, who had 
the power successfully to say “Lazarus come forth!” 
Of all drugs not only to allay the pain, but also to shorten 
the sthenic stages of inflammation, when its seat is an extensive 
serous surface opium is the chief; aconite and belladonna are 
frequently employed as assistants to it. 
Enteritis in the horse, on account of the great extent and 
vascularity of these viscera in solipeds, is incurable, but mor¬ 
phine and atropine, or large doses of the crude drugs from which 
they are derived, afford the greatest relief. 
As an antipyretic, alcohol with acetanilid or some of the 
other coal tar products, gives great satisfaction.
