176 OPHIDIANS. 
Making in all 124 cases, which may be classified as follows, 
viz.: Cobras bitten by Cobras, 5 cases; 4, no effect; one 
case died in 3 hours 22 minutes. Cobras injected with Cobra 
poison, 4 cases; one died in 29 minutes, another in 5 hours 
40 minutes; 2 cases recovered. Dogs bitten by Cobras, 11 
cases, varying from 6 minutes to 1 hour 3 minutes; the 
greater part of the cases, however, average from 25 minutes to 
45 minutes. Of dogs injected with Cobra poison, one died in 
1 minute 10seconds. Dogs that had the ligature applied and 
cauterized, one died in 1 hour 43 minutes, one in 35 minutes, 
Fowls died in from 34 seconds to 3 hours. 
In three separate experiments fowls died from injected blood 
from fowls killed by Cobras ; and in a third case a chicken died 
in 9 days from injected blood of a fowl that had died from 
injected blood of a fowl previously killed by a Cobra-bite. 
This last case is one of the most interesting in the whole 
series of experiments, as it scems to accord with Prof. Hal- 
ford’s theory of the poison containing a germinal matter, and 
also of Dr. 8. Weir Mitchell’s theory of its nature as a ferment.* 
Injections of liquor ammonia in fowls were not attended 
with success in any case. In cases of ligatures applied to the 
limb before the bite death occurred in 28 minutes, and 44 min- 
utes, which shows that despite the compression of the arteries 
and veins in the limb, a ligature cannot be put on so tightly 
but that the poison will pass with great rapidity into the gen- 
eral circulation, and produce death. 
Carbolic acid was given toa Cobra; it recovered in one case, 
but in all the remaining cases death ensued in 5 minutes, 20 
minutes, and 25 minutes. The bull and the goat bitten by Co- 
bras, which were treated by fowl’s liver rubbed on the wound 
and Tanjore pills administered, both recovered, although a 
fowl treated in the same way died in 6 hours 40 minutes.
