104 LARYNGITIS. 
The signs of the disease becoming worse are, increased noise in the 
breathing; the respiration and pulse quicken; the cough is suppressed ; 
the nasal membrane changes to a leaden hue; the standing becomes 
unsteady; the horse moves about; partial sweats break forth, ete. 
The symptoms of improvement are, the membrane becoming paler, or

to remove dust, and it should also be picked, to take away any harsh 
substances, pieces of stick, or thistle leaves. Then, the fodder being 
perfectly clean, should be sprinkled with water and allowed to remain 
soaking, at least six hours prior to its being placed before the animal. 
The oats, likewise, should be twice sifted and once examined thoroughly 
by the hand. Afterward, warm water ought to be freely poured upon 
them, and the grain be permitted to soak six hours before being put

The popular opinion declares sore throat to be always present during
