thunberg

Updated: June 19, 2025

Thunberg was shown the snake-stone used by the boers at the Cape in 1772, which was imported for them "from the Indies, especially from Malabar," at so high a price that few of the farmers could afford to possess themselves of it; he describes it as convex on one side, black and so porous that "when thrown into water, it caused bubbles to rise;" and hence, by its absorbent qualities, it served, if speedily applied, to extract the poison from the wound.
