Jorge Tadeo Lozano, Memoria sobre las serpientes — an American snakebite programme that prints its own negative result

The zoologist of the Royal Botanical Expedition of New Granada published in the Semanario a memoir on the snakes of the kingdom and on the remedies for their bites. It sorts the remedies by how they are supposed to act, sets out three experiments to settle what venom is for, asks observers in every province to use Linnaean names — and records that the celebrated guaco failed: a woman bitten on an estate was dosed heavily inside and out and died thirty hours later.
