The art of distillation: Or, A treatise of the choicest spagyrical preparations, experiments, and curiosities, performed by way of distillation… by John French (1667)

retort_receiverThe physician John French was born at Broughton, Oxfordshire, in approximately 1616.  He entered New Inn Hall in 1633, one of Oxford University’s earliest medieval halls, and graduated with a Degree in Arts in 1637 and a Masters in 1640.  He pursued work in Great Britain’s Parliament army during the Civil War, eventually becoming one of only two physicians to the whole army, and was created Doctor of Physic in 1648.

furnaceFrench was a follower of Paracelsus’ school of alchemy, which was critical of certain aspects of traditional alchemy.  He lived in an era when the new science of chemistry was developing, and he was keen to discover fresh medical uses for various chemicals and compounds.  His bias against Galenic medicine, with its underlying principle of humorism or the four humors – black bile, yellow bile, blood and phlegm – as advanced by the ancient Greeks, and which dominated Western medical science for more than 1300 years, is clear in his works.  In his 1654 publication, The York-shire spaw…, French explored the causes, virtues and uses of the ‘vitrioline’, ‘sulphur’, ‘petrifying’ and ‘Mugnus’ medicinal wells near Knaresborough, North Yorkshire.  The book is a fine example of French’s enthusiasm for new chemistry and its application to medicine.

The Library’s copy of The Art of Distillation (1667) is the second edition which is divided into eight separate “books” – essentially chapters on distillation, its three principle definitions, its methods, and the best furnaces and vessels to use in the process.  By far the most curious of chapters is number four, “Of animals”.  Here, the reader can find no less than 40 experiments which utilise human and animal organs, each said to offer medicinal relief for a variety of ailments.  Below are some of the more unusual experiments:

Elixir of Mummies is made thus.

“Take a Mummie (viz. of Mans-flesh hardened), cut small four ounces, Spirit of Wine terebinthinated ten ounces, put them into a glazed vessel, (three parts of four being empty) which set in Horse-dung to digest for the space of a month; then take it out and express it, let the expression be circulated a month, then let it run through Manica Hippocratis; then evaporate the Spirit, till that which remains in the bottom be like an Oyl, which is the true Elixir of Mummie.  This Elixir is wonderful preservative against all Infections, also very Balsamical.”

A Water and Oyl made out of Hair.

“Fill an earthen Retort with Hair cut small, set it over the fire, and fit a Receiver to it, and there will come over a very stinking Water and Oyl.  The Water and Oyl is used in Germany to be sprinkled upon fences and hedges, to keep wild and hurtful Cattle from coming to do harm in any place; for such is the stink of this Liquor that it doth affright them from coming to any place near it.”
