the contrary, the serious attention of all those who do not 
profess a blind opposition to all inventions whatever, and who 
do not confound, in an unjust condemnation, all rational sup¬ 
positions, the object of which is truth. Among the seventy 
experiments made by M. Polli we will select some of the most 
conclusive, in order to avoid a repetition of details nearly 
identical; but we will, at the end, give a succinct summary- 
of the whole of these experiments made by the author. 
Experiments made with pus .—To a dog weighing four kil., 
ten grammes of sulphite of soda were given in the space 
of five days. On the 19 th of November, I860, at 3 p.m., 
one gramme of thick putrid pus was injected into the saphena 
vein taken from an abscess on the back of an old man. 
This pus had previously been diluted with an equal bulk 
of water, to render it more fluid, and to prevent it forming 
obstruction in the veins; immediately after the injection 
the dog seemed stupefied, lay down, and refused all food 
during that day. On the next day he had recovered his 
liveliness and appetite. Two more grammes of the sul¬ 
phite were given in two doses. On the 19th another injec¬ 
tion of pus was made into thejugular vein. The same symp¬ 
toms of stupefaction and prostration appeared for a few 
hours after the injection, but the next day the dog was 
better. He was subjected regularly to taking two grammes 
of the sulphite of soda until the 23rd. The dog rapidly 
recovered his liveliness and his appetite, the wounds resulting 
from the apertures assumed a favorable aspect and cicatrized 
rapidly; so much so, that the animal might be considered as 
perfectly recovered five days after the second injection of 
pus; and even during that time the general state of the dog, 
as well as the wounds made for the injection, presented but 
slight signs of derangement. On the 17th and 19 th similar 
doses of the same pus were injected into the femoral veins of 
another dog, bigger than the former (weighing about eight 
kil.), but to which no sulphite of soda was given neither 
before nor after the injections. These operations were 
easily accomplished, and the dog seemed to suffer very 
little. After the first injection the dog was stupid and dull; 
the next day he had somewhat recovered, and took his 
food; after the second injection he was very much dis¬ 
tressed, and had several watery evacuations; the next day 
he lay down continually in his kennel; he refused all food. 
The pulsations at the heart were feeble and accelerated 
(140 per minute), the respirations frequent (14 per minute). 
The following days he became much worse; he could 
hardly move, and when made to walk he took a few steps
