NATURE AND ANALYSIS OF THE POISONS. 141 
Experiment No. 4. An albino rabbit, of the same size and 
age as the first one, had injected into the femoral artery of the 
left hind leg twenty minims of the diluted poison at 2.53% 
P.M. It was remarked in this case that the point of the 
syringe penetrated the artery. Made a preparation of five 
drops of the first decimal dilution of the gall of a South 
American Viperine snake in four ounces of fresh water. 
Gave of this, at 2.59 p.M., first dose; 3.034 second dose; 3.08 
p.M. third dose; when it became evident that the antidote was 
producing no effect, and it was discontinued. At 3.28 P.M., 
or in thirty-four and a half minutes, death ensued. At 4 P.M. 
a portion of the blood, poured into a deep dish, had formed a 
firm coagulum, with very little apparent change of color. 
Deductions from the foregoing Experiment. That as the point 
of the syringe had penetrated the artery, and as the albino 
organization is so peculiarly sensitive in every respect, death 
had ensued much quicker than in Experiment No. 1. As to 
the action of the antidote, it was evident that the gall of the 
Cobra was necessary to counteract the effects of the Cobra 
poison, as the range of action of the gall must necessarily be 
similar, in a pathogenetic (therapeutic) sense, to the action of 
the poison in a toxicological sense. 
Experiment No.5. With the poison of a South American 
Viperine snake called Bogui Dorada (or Gilded Mouth)—a 
quantity of about four drops of the poison to each ten minims 
of liquid. 
At 3.144 injected twelve minims near the femoral artery 
of the right hind leg of a black rabbit, of same size, age, and 
weight as No. 4. At 3.192 tried to force into his mouth a 
dose of same antidote as used in Experiment No. 2, but he 
obstinately refused to swallow. 3.27 P.M. tried to give a 
dose of antidote—same result; 3.44, ditto; 3.58, ditto. 40.8,
