MISCELLANY. 
of the salt, dissolved in 2 ounces of water, were given to a full-grown 
rabbit. Five minutes after the animal took food ; in twenty minutes the 
respiration became irregular, and thirst supervened. It now received a 
second dose of 15 grains, which produced very anxious respiration, and, 
attempts, as it were, at vomiting, which were rendered abortive by the 
peculiar structure of its stomach. In about an hour and a quarter, the fore- 
feet were seized with trembling ; in two hours the strength had sunk very 
much, and there was also incipient paralysis of the hind-feet. Death en- 
sued in two hours and twenty minutes, with convulsions and evacuations 
of the faces and urine. The body was examined two hours after death ; 
the jaws were firmly closed ; the cerebrum, cerebellum, and spinal marrow 
were gorged with blood, and somewhat softer than usual ; the trachea 
and lungs were likewise gorged ; the heart was flabby, and the right au- 
ricle was filled with fluid blood. The stomach was injected, its mucous 
membrane was partially destroyed, and its contents, when tested, showed 
the presence of chromium. The intestines were filled with mucus. The 
liver appeared softened. 
Exp. ii. A pigeon received 30 grains, made into a pill, with crumbs of 
bread, in doses of 10 grains, with an interval of half an hour between each 
dose. Soon after the last dose the animal became rigid, and made in- 
effectual attemps to vomit. It died in about four hours with slight con- 
vulsions. Its body was examined three hours after death ; the body was 
rigid, the brain gorged with blood in a remarkable degree, and it, as well 
as the spinal cord, appeared softer than natural. The crop was injected, 
and contained nearly the whole of the pills as they had been swallowed; 
the stomach contained some chromium; the whole intestinal canal was 
reddened; the heart was flabby; and the lungs were gorged with blood. 
Exp, hi. A wound was made in the neck of a moderate-sized bitch, and 
30 grains of the salt were introduced beneath the integument, and the 
wound was then stitched up. Frequent evacuations of the bowels and 
bladder followed in about a quarter of an hour, and immediately afterwards 
vomiting and trembling. At first the matter vomited consisted merely 
of the food ; it then became mucous, and after some hours resembled the 
serum of blood. The usual reagents showed no indications of the pre- 
sence of chromium. In eight hours the hind-feet were paralyzed, the fore- 
feet continued to tremble violently. The animal died in eleven hours. 
The body was examined ten hours after death ; it was rigid, and had an 
unpleasant smell ; the wound was dry, whitish, and contained a trace of 
the salt; the cerebrum, and cerebellum were gorged with blood, and, 
along with the medulla, much softened. The lungs were filled with 
blood, as was also the right side of the heart. The stomach and upper 
portion of the intestinal canal, and the bladder, were reddened, but their 
contents showed no trace of the presence of chromium.
