galls of serpents, prepared and administered as recommended 
on another page, and although they necessarily cling to many 
“hocus pocus” manipulations and performances, yet now they 
boast of never losing a case! 
The first edition of the present work, published in 1870, 
in Bogota, serves many of them as a manual, and has initi- 
ated a system of treatment in cases of snake-bites which is 
gradually spreading itself throughout the entire country. 
Some of the tribes of the North American Indians use the 
galls of serpents (mixed with decoctions of herbs of little or

tribes in Venezuela, and in the valley of the Amazon. 
A singular fact appears to be recognized in common by

witnessed the.truth of this fact in a great number of cases. 
There is some psychological influence, some profound, un-

few rods in the rear, came up to, and found the reptile winding 
and coiling itself up, as though in great pain, soon cease the 
violence of its movements, and appear to lose all power of 
locomotion, remaining semi-torpid for nearly an hour there- 
after! This is a fact attested by hundreds of Curers, and
