Now, as will be seen from these statements, this South Ameri¬ 
can plant really seems to possess all those properties which might 
be supposed necessary to constitute a true physiological antidote 
to serpent venom, and so far as our limited experiments go, there 
appears to be good warrant for such a belief, as in all of our ex¬ 
periments the so-called antidote was first tried on healthy animals, 
without producing any ill effects. The first experiment was as 
follows: 
Nov. 28—12:20 a.m. —Injected 5 minims of solution rattle¬ 
snake venom into left leg of strong rabbit, following immediately 
by 10 drops of fluid ext. jaborandi, in 10 drops of water; and 10 
drops jaborandi and £ oz. w T ater was forced into the animal’s 
stomach with a syringe. 
2:30 p.m. —Animal slightly lame in the injected leg, holds it 
up when walking; but eats well. 
Nov. 29—11 a.m. —Animal still a little lame, slight swelling 
and tenderness of the injected leg—otherwise seems to be in good 
condition. 
Nov. 30—11 a.m. —Animal in about the same condition as 
yesterday—but improving. 
Dec. 1—11 a.m. —Animal slightly lame; a hard tumor formed 
at the seat of injection. 
Dec. 2—11 a.m. —Animal in same condition as yesterday ; 
appetite normal. 
Dec. 5—Swelling entirely gone, animal perfectly well. 
It was noticed in this case that the animal urinated freely and 
very frequently, and that the mouth and nostrils were very moist. 
Chickens and pigeons being peculiarity susceptible to venom it 
was determined to try the effect of the jaborandi upon them, 
and on 
Dec. 3—12:30 p.m. —Injected 5 minims of Crotalus venom 
into the leg of a chicken, followed by 10 minims of fl. ext. jabor¬ 
andi, in water, by the stomach. 
1 p.m. —Chicken appeared not so well, lying down. Gave 10 
minims more of jaborandi in stomach.
