One of the earliest descriptions of such a thing is that attributed
to Abbé Grosier, in his "Description of the Chinese." He there gives
an account of the use of a stone called the serpent-stone in "Tang-King."
This was applied, stuck fast, absorbed the poison, dropped off, and the patient
was freed. The stone was washed in lime-water, dried and could then be used
