REPORT OF CASES. 
Nothing was done about it, and no particular change in the animal’s 
actions was noticed until about six o’clock, when he refused to eat his 
supper, but showed no other sign of distress. Upon this, the wisdom ol 
the neighborhood administered in solution about one and one-quarter 
pounds of Epsom salts, and the animal, showing no signs of pain, was 
left alone through the night. In the morning the same state of things 
continuing, and the bowels not having moved, my services were called 
into requisition, and I saw him at nine a. m., June 1st. He stood with 
his legs well apart, head drooping, and a peculiar listless , vacant expres¬ 
sion of the eye ; no perceptible pulse at jaw, and no artery; extremities 
cold , and with but slight sensibility ; there was an awilessness in his man¬ 
agement of them during motion, but still not seeming to amount to 
paralysis, even remotely ; respiration deep, slow and with apparent ease. 
There was not at this time , nor at any other , the slightest symptom of ab 
dominalpain. He died quietly at two p. m. A hurried, and, conse¬ 
quently, imperfect post-mortem examination, showed the mucous mem¬ 
brane of the stomach intensely inflamed, immensely thickened, and of 
a deep mulberry color evenly distributed ; its solid contents (hay and 
grass) of that bright green color artificially given to pickles by the use 
of copper. The membrane of the small bowel was thickened, but not 
to such an extent as that of the stomach, and of a bright arterial color ; 
its contents fluid, and with a considerable admixture of extravasated 
blood; membrane of the colon, no thickening, but moist, with a decided 
blush ; no peritoneal inflammation throughout. In poisoning by salts of 
copper, Drouard found that six grains of the sulphate given to a dog 
caused death in half an hour, but left no appearance of inflammation; 
two drachms have been given with a like result, except there was a 
blueness of the villous. A drachm applied to a wound, caused in the 
dog rapid prostration, and death in four hours. “ Injected into the 
jugular vein, it speedily reduces and arrests the action of the heart, 
fifteen grains proving fatal in twelve seconds.”— (Dun.) In poisoning 
by arsenic, the time required to produce death in a given number of re¬ 
ported cases was from four to nine days, with all the evidences of active 
inflammation of the mucous membrane of the whole digestive canal. 
“ But sometimes these symptoms are almost or entirely absent, and in¬ 
stead of the patient running the usual course of arsenical poisoning, 
profound coma sets in, from which he never wakes, but dies in a few 
hours, the mucous membrane of the stomach and intestines being free 
from all inflammation.”— (Virchow.) “ After a poisonous dose frogs 
become apparently paralyzed; at the same time they have lost all sen-
