six kil. ten grammes of the sulphite of soda were adminis¬ 
tered daily, made up into five balls with bread-crumbs, for 
three consecutive days. On the 9th of June, 1861, the dog 
was in good health, and eight grammes more of the sulphite 
were given to him. Afterwards, a gramme and a half of 
putrefied human blood was injected into the right femoral 
vein. The dog became stupefied, sad, and refused his food 
during the whole of that day; the next day he was lying 
down in his kennel, but without stupefaction. On the third 
day after the injection he began to feed; became more 
active. On the fourth day he had completely recovered ; 
the wound assumed a healthy aspect. Eight days after this 
the dog died without having previously shown any sign of 
illness, except great haemorrhage from the wound, which 
took place during the night on which he died. 
In order to make a comparison between the two preceding 
experiments, one gramme of the same putrid blood was 
injected on the same day in a small dog (weighing five kil.) 
without being submitted to any preventive remedy. Directly 
after the injection the dog vomited, and alvine evacuations 
and tenesmus supervened. He seemed anxious and agi¬ 
tated, remained standing on his four feet, as if petrified, for 
several hours, holding his head down. Death took place six 
hours after the injection. At the autopsy the lungs were 
found engorged, and presented ecchymotic spots on their 
surface; black clots of blood were found in the right ven¬ 
tricle of the heart; the liver was of a dark-red colour; the 
mucous membrane of the stomach was normal, but that of 
the intestines was of a dark-red purplish colour in places, 
even to the rectum, though a little less dark coloured in the 
ileum. Thus it is shown that in the two other dogs the ad¬ 
ministration of the sulphite and hyposulphite of soda suc¬ 
ceeded in protecting the animals against the morbific effects 
of a toxic substance, which in smaller doses killed another dog 
not fortified by the same remedy. In order to give still 
greater value to these results, the dog which had been pre¬ 
served by the hyposulphite was submitted to a counter¬ 
proof, the result of which was most conclusive. Eleven days 
after this experiment, when the dog was considered in per¬ 
fect health, a fresh injection of one and a half gramme of 
the same putrid blood was made into the femoral vein, without 
any previous administration of sulphite. The dog died in 
three days, from gangrene in the leg where the injection had 
been made; the lungs were gorged and covered with ecchy¬ 
motic spots; there was extravasated blood in the stomach, 
the mucous membrane of the intestines was purple, and
