EXPERIMENTS WITH SNAKE-POISON. 1738 
No. 123. A dog bitten by a Hydrophis; died in 1 hour. 
No, 124. A fowl had the blood of No. 123 injected into its 
body; died in 12 hours. 
Different kinds of poisons, namely, Cobra, Daboia, Ophio- 
phagus, and Echis, applied to the conjunctiva of different 
animals, produced intense local inflammation, but in no case 
death. 
The composition of the Tanjore pill* is as follows, viz.: 
Equal quantities of Arsenic (white); Nervalam almonds (a 
narcotic); Root of Velli-navi (a purgative); Pepper; Root 
of Neri-visham (a purgative); Mercury. Mix and rub the 
Mercury with the sap of the Wild Cotton (Asclepias gigantea, 
Linn.), until the globules disappear entirely. 
The dogs used in the preceding experiments were all full- 
grown Pariahs, a large bony animal common in India.
