will consume. Untie the head and place the horse in slings; employ 
the arnica lotion night and day, until the slough is thrown off, which, 
having taken place, change the liquid application for the solution of 
chloride of zinc—one scruple to the pint of water—and continue to 
employ this last lotion after precisely the same manner as has been pre- 
viously directed. 
Probabilities, however remote they may seem to be, are here endeayv- 
ored to be anticipated; although the author’s experience cannot recall 
a single case where the arnica lotion has been used with proper assiduity, 
and any but the most happy results have followed. When an animal has 
fallen violently to the earth, and has been, in the first instance, shown to 
the writer with much tumefaction and excessive tenderness, a slough has 
in exceptional cases followed; but never has the enlargement or the 
sensitiveness increased under the proper use of the arnica lotion. The 
slough, moreover, in such instances, has been superficial, only entailing 
loss of hair, and never occasioning open joint. 
All horses are exposed to these accidents for the reasons already 
stated. Whenever such misfortunes occur, employ the arnica lotion. 
Should the skin be divided, still use the arnica lotion until copious sup- 
puration is established. The secretion once seen, resort to the lotion 
formed of chloride of zinc and water—one grain to the ounce—which 
operates most marvelously upon all suppurating wounds. 
No absolute period can be stated which a case of broken knees, when 
severe, ought to occupy. The danger, however, is generally passed by the 
expiration of a week, and the cure commonly entails loss of services for 
a couple of months.

TREATMENT. AUTHOR EVER HAD UNDER HIS CARE. 
When adopting the foregoing mode of treatment, no bandages are to 
be employed. Such wrappers only augment the heat inherent in every 
species of inflammation. They dam up the pus and speedily become 
foul and offensive rags; cleanliness is one of the primary requisites 
toward good surgery.
