'The great work on which he spent his latest years was a system of philosophy set forth in ' Physica vetus et vera'. 

 In this laborious work, on which years had been spent, and part of which he had to write twice in consequence of an 

 accident by fire to the MS., the author pretends to establish a philosophy founded on principles collected out of the 

 Pentateuch. In a very confused manner he mixes up his notions on the atomic theory with passages from Greek and 

 Latin writers as well as from the Bible. The book, however, attracted attention '. D. N. B.

7296 DIGBY (Sir Kenelm; F.R.S.) A LATE DISCOURSE made in a SOLEMNE ASSEMBLY of 

 Nobles and Learned Men at MONTPELLIER in France, touching the CURE of WOUNDS by the 

 POWDER of SYMPATHY; with INSTRUCTIONS how to MAKE the said Powder; whereby many 

 other Secrets of Nature are unfolded, rendered faithfully out of French by R. WHITE ; 2nd Edition, 

 corrected and augmented, with Index, 24mo. old calf (some II. soiled, otherwise a SOUND COPY) ; 

 VERY RARE, 2. 10* R. Loivndes, 1658 



' Digby first described his well-known weapon-salve, or powder of sympathy, in the discourse alleged to have been 

 delivered at Montpellier in 1658. Its method of employment stamps it as the merest quackery. The wound was never to 

 be brought into contact with the powder, which was merely powdered vitriol. A bandage was to be taken from the 

 wound immersed in the powder, and kept there until the wound healed. He says that he learned how to make and apply 

 the drug from a Carmelite who had travelled in the Eist. He first employed it about 1024 to cure James Howell of 

 a wound in his hand, and he adds that James I. and Dr. Mayerne were greatly impressed by its efficacy, and that Bacon 

 registered it in his scientific collections'. Sidney Lee.
