perfectly. He had animals bitten : a wolf three months old; 
thirty minutes after the bite, when symptoms had become marked, 
six drops of antidote were given ; wolf became well almost imme¬ 
diately and ate a piece of meat. Same wolf bitten next day in 
three places, but there was some delay in giving the antidote; 
wolf died comatose in twenty-seven minutes. Snake made to bite 
a dog, which died because antidote could not be given. Forty- 
five minutes after, same snake was made to bite another dog; in 
three minutes after the injury the antidote was given before 
symptoms developed; in fifteen minutes another dose, and in two 
hours he appeared perfectly well. Dr. Coolidge in same paper 
reported case of girl fifteen years old bitten at Fort Riley; ten 
minutes after, the doctor placed a ligature above the bite, made 
free incision and gave the antidote, repeated twenty minutes 
after, injecting into the finger Brainard’s preparation of iodine. 
Girl got well with extensive suppuration of back of hand. 
The formulae for the preparation of this antidote is as follows:

After Dr. Hammond’s experiments so much faith was placed 
in this preparation that it was furnished to all the military posts 
in the West and South, and the writer remembers to have seen 
a bottle of it occupying a prominent position in the serpent room 
of the Academy of Natural Sciences, Philadelphia, then in charge 
of Prof. E. D. Cope. 
Mr. Xantus de Vesey performed a number of experiments 
with the Bibron antidote, and states that none of his animals per¬ 
ished of snake bite when the remedy was used. Dr. S. Weir 
Mitchell experimented upon sixteen dogs, with that singular care 
for which he is noted, with the following results, which are simply 
negative. Of eight dogs bitten and treated with the antidote 
two died, while of eight bitten and not so treated three died. It
