EFFECT OF INJECTION INTO THE VEINS. 
minute, and this inordinate evacuation continued during several 
days. The cedematous swelling disappeared, but it appeared a 
few days afterwards, on the chest and throat. The respiration 
became exceedingly difficult, embarrassed, and sonorous, with 
violent beating at the flanks, and so continued during five days. 
These circumstances determined us to destroy him for anatomical 
purposes. 
The viscera of the abdomen were in their natural state. One 
of the lobes of the lungs was thickened, engorged, red, friable, but 
did not contain any tubercle. The brain was injected, and pointed 
with blood in its white substance; while its grey substance was 
uniformly reddened. The lesions in the nasal cavities were 
attributable to glanders, which existed in its most advanced stage. 
There were ulcerations or chancres, and some tubercles not 
ulcerated. 
Another horse, likewise glandered, but in good condition, was 
subjected to the same experiments, and with similar results : 
the injections consisted of five grains, repeated on each alternate 
day. He too was killed for anatomical purposes, and the only 
difference which appeared on dissection was that the spinal marrow 
was a little softened. 
On the following day we injected into the jugular of another 
horse, a pint of alcohol, at 20 (77 Fah.) degrees. The animal soon 
began to stagger, and presently fell, and exhibited many of the phe¬ 
nomena of drunkenness. These disordered movements continued 
about an hour. In the mean time the pulse was hard, and the 
respiration frequent; the air which was expired had the smell of 
alcohol; the mucous membranes of the nose and the mouth were 
highly injected, and the various secretions augmented. 
This animal presented appearances very different from those 
produced by the injection of the emetic tartar. The movements 
of the muscles were characterised by feebleness and incertitude. 
The limbs bent every instant under the weight of the body. The 
animal was without force or energy, and his occasional movements 
were not subjected to the dominion of the will. He appeared 
like a horse affected with staggers. The horse which was under 
the influence of the tartarized antimony exhibited rapid con¬ 
tractions of the limbs, violent and convulsive. 
To ascertain whether, in the horse, ammonia would destroy the 
effects of alcohol on the system, half a pint of alcohol at 20 
(77 Fah.) degrees, was injected, on the 25th of March, into the 
jugular of the same horse. Immediately after the injection, he 
was evidently under the influence of the drug; but as the quantity 
was small, the symptoms, although similar, were not so marked 
as in the former experiment: the injection, however, had not 
terminated before the breath was tainted with the smell of alcohol,
