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

 In this laborious work, on wliich years had been spent, and part of which he had to write twice in conseciuenco of au 

 accident by tire 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 b<iok, however, attracted attention '.—D. N. B.

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

 delivered at Montpellier in 105S. Its method of employment stamps it as the merest <iuackery. The wound was never to 

 be brought into contact with tlie 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 tirst employed it about l&2i to cure James Howell of 

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

 registered it in his scientific collections'. — Siilnen Lee.
