POISON IN AMMONIA.

be observed iu the two hur&es having an artificial opening in their 
trachea. The expirium passing through the tubes is entirely de¬ 
void of smell while the air passing through the nostrils after shut¬ 
ting off the tube is very offensive. 
October 20.—Discharged three horses ; others doing well save 
Charley and Joe, which are still in a doubtful state. George is 
eating well and breathes without impediment. A large eschar is 
extracted from Charlie’s left nostril; it is elliptical in shape, 5 
inches long, 2 inches wide and as thick as harness leather; 
smaller ones are removed from Joe and a few others. 
October 21.—The gross symptoms do not vary much. A 
grey horse, Barney, has a chill; his temperature is 104° and his 
pulse 76 per minute, and looks somewhat despondent. Charley 
has considerable breathing difficulty, not only attributable to his 
lung trouble but also to his nasal obstruction. To relieve this, a 
tube is introduced into his trachea, from which flows a larg-e 
quantity of pus of an offensive odor, unquestionably proceeding 
from abscesses in the lungs. This phenomenon alone is sufficient 
to warrant his destruction, but from the fact that his breathing: is 
rendered more comfortable by the use of the tube, I conclude to 
postpone it. Joe breathes very fast, about 60 per minute, but 
has no trouble in his nasal passages now. His pulse is 84 per 
minute; temperature 100° and appetite fair. 
October 22.—Condition of all patients is encouraging save 
Charlie’s. He is getting quite weak. Fell while being led 
across the floor, but rose without assistance. .Recognizing the 
fact that no chance for his recovery remains, I ordered him de¬ 
stroyed. Joe lies down frequently; his symptoms are still quite 
important, but he has a good appetite. Barney’s pulse and tem¬ 
perature continue well up, but otherwise looks favorable. 
October 23.—Horses all improving. Excepting Joe’s, their 
pulses range from 42 to 66 per minute and the thermometer 
registers below 103°. Appetite is fair and they lie down to rest. 
The breathing, however, in general, is markedly accelerated. 
The corneal opacity in some still prevails. It is needless to state 
that emacation has become quite obvious by this time. They all 
have a slight mucous discharge from their nostrils and an occa¬ 
sional cough.
