The Art of Distillation (Illustrated)

John French is chiefly remembered for publishing in 1651 The Art of Distillation, a detailed handbook of knowledge and practice at the time, said to be possibly the earliest definitive book on distillation.However, it has been claimed that much of it was a translation of an earlier (1500) German text by Hieronymus Brunschwig.

John French was also the translator of Three Books of Occult Philosophy in 1651 (original: De Occulta Philosophia libri tres by Heinrich Cornelius Agrippa, although he was only identified as J.F. in that work.All other English translations of the book available have been merely edited versions of his work.
