Original Edition of this immortal precursor of the Revolution. The numerous plates on science and mechanical 

 engineering it contains are of great historical interest, apart from its disruptive influence on orthodox pliilosophy and 

 religious belief. ' m i i i

 Reasonable Souls. With two Discourses of the Powder of Sympathy and of the Vegetation

' Digby first described his -Hell-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, whicli 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 East. He first employed it about 1024 to cure James Howell of a wound in his 

 liand, 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.

1054 DIGGES (Leonard) : An Arithmeticall Militare Treatise, named Stratioticos ; com- 

 pendiously teaching the Science of Rubers, as well in Fractions as Integers, and so much of 

 the Rules and Aequations Algebraicall and Arte of Numbers Cossicall, as are requisite 

 for the Profession of a Soldiour. Together with Modern Militare Discipline, Offices, 

 Laaves and Dueties in euery wel gouerned Campe and Armie to be obserued : Long since

 rare, £8. Ss Henrie Bynneman, 1579 



The first edition of this work is excessively rare, no copy having happened for sale for many years. A second edition 

 was published in 1590. 



'He [Tliomas Digges] became very proficient in mathematical and military matters, having spent many years 'in 

 reducing the sciences mathematical from demonstrative contemplations to experimental actions', in which he was aided 

 by his father's observations, and by conferences with the rarest soldiers of his time.'— D. N. B. In 1.^82 he was chosen by 

 the Privy Council overseer of the works and fortifications at Dover Harbour. Tycho Brahe praised him highly iri a letter 

 to Sir Thomas Savelle, dated Dec, 1590.

 stained, and a few headlines shorn] ; rare, £1. 10* F. Kyngston, 1625 



There is no copy of this edition in the British Museum. Digges is probably rightly credited with having anticipated 

 the discovery of the telescope.

 Bookes, Longimetra, Planimetra, and Steriometria, containing Rules manifolde for mensuration

' Thomas Digges ranks among the first mathematicians of the XVI. century. Although he made no great addition to 

 science, yet his writings tended more to its cultivation than perhaps all those of other writers on the same subjects put 

 together.'--/. 0. Halliwell-Phillipps. 



' Tlie 21st cliapter of the first book includes a remarkable description of ' the marvellous conclusions that may be performed 

 by glasses concave and convex, of circular and parabolic forms. He practised, we are tliere informed, the ' multiplication of 

 beams' both by refraction and reflexion; knew that the parabok)idal shape 'most perfectly doth unite beams, and most 

 vehemently burneth of all other reflecting glasses', and had obtahied with great success magnifying eflects from a com- 

 bination of lenses . . . The assertion that [Leonard] Digges anticipated the invention of the telescope is fully justified.'— 

 Miss Agnes M. Gierke.
