had been injected, M. Polli performed the following ex¬ 
periments, as other proofs. In a dog weighing seven 
kil. he injected only one gramme of putrid blood on the 
31st of January, J86l. The animal seemed very giddy 
after the operation, he remained down, and was dull; he 
refused his food during the five following days, and only 
moved with difficulty; when made to do so, he limped. 
The wound extended and suppurated. Towards the sixth 
day he began to recover, and to take a little food; was 
more active. In about a fortnight he became convalescent, 
and recovered his usual vivacity, and the wound advanced 
towards cicatrization. This experiment confirmed the uni¬ 
form deleterious effect of putrid blood, when introduced into 
the circulation, and shows that, if the dose is not large 
enough to kill the animal, it provokes a serious malady. 
The same day (January 31st) he injected into the right 
femoral vein of another dog, of the same size as the last, one 
gramme of the same putrid blood, mixed with three grammes 
of sulphite of soda in solution. After the operation the dog 
remained stupefied; the whole of that day he did not move 
out of his kennel; about the middle of the next day he took 
a little food and drink; the third day he was lively, ate all 
his food eagerly, ran about, but holding up the leg on which 
the operation had been made. The wound was dry, and had 
a favorable aspect. On the 9th of February, 1861, the 
same experiment was repeated on another dog, in which w r as 
injected into the femoral vein, first one gramme of putrid 
blood; one minute after, one gramme and a half of sulphite 
of soda, dissolved in five grammes of water; the animal 
became somewhat stupefied, refused his food during two 
days, but was not in a state of somnolence; he afterwards 
became lively, and recovered his strength; three days after 
that he w’as again in perfect heath. These three experiments 
evidently show 7 that, though the introduction of putrid 
blood, mixed with sulphite, affected two of the dogs, it only 
caused in them a slight derangement, in which the typhoid 
symptoms, or the signs of septic infection, were ascer¬ 
tained to be absent. This, however, characterised the ma¬ 
lady in the third dog, in which the putrid ferment was 
injected without the sulphite. They also demonstrate that it 
is really the effect of the sulphite on the putrid ferment 
which neutralizes the morbific influence in the blood itself. 
They also demonstrate that the sulphite of soda is not a 
poison, for three grammes of the saturated solution had been 
introduced in one injection, which is equal to two grammes 
three demigrammes of the solid sulphite. In a dog weighing
