A strange method, which said to have been employed by the Borgias, and was afterwards used in France, was a combination of arsenic with the secretions or products of decomposition of an animal to which it had been administered. The poison was prepared by cutting open a pig, and well sprinkling the carcase with arsenic or other poison. Then it was left to putrefy, after which the liquids that ran from the decaying mass were collected, and these formed the finished poison.
As science advances, opening up fresh fields for research and poisons of a still more deadly nature are revealed, so the chemist sets to work to discover methods for their certain detection, and thus renders the poisoners' fiendish work more difficult.
It is well to remember that even the most deadly poisons have their proper use, and in skilled hands prove valuable instruments in combating many diseases that afflict suffering humanity.
