John French's Art of Distillation

• French, John (1651), The Art of Distillation: or, A Treatise of the Choisest Spagyricall Preparations performed by way of Distillation, London: Printed by Richard Cotes and are to be sold by Thomas Williams at the Bible in Little-Britain without Aldergate 
• French, John (1667), The Art of Distillation: or, A Treatise of the Choicest Spagyrical Preparations, Experiments, and Curiosities performed by way of Distillation, London: Printed by E. Cotes for T. Williams at the Bible in Little-Britain 

A famous Spirit made out of Cranium-humanum.

Take a Cranium-humanum as much as you please, break it into small pieces, which put into a Glass-Retort well coated, with the large Receiver well suted, then put a strong fire to it by degrees, continuing of it till you see no more fumes come forth; and you shall have a yellowish Spirit, a red Oil, and a volatile Salt.

Take this Salt and the yellow Spirit, and digest them by circulation two or three months in Balneo, and thou shalt have a most excellent spirit.

This spirit is of affinity with, if not the same as that famous spirit of Dr. Goddard's in Holborn.

It helps the Falling-sickness, Gout, Dropsie, infirm Stomach; and indeed strengthens all weak parts, and openeth all obstructions, and is a kind of Panacæa.
