The "arithmeticall jewell" is an instrument with a flat grid of semi-circular, rotating brass wedges, devised to facilitate addition, subtraction, multiplication, division, and the extraction of roots. A patent for making a device “by which all questions arithmetical may be resolved without the use of pen or compters [counters]” had been granted on 27 March 1616 to “John Harpur, Wm. Pratt and Jeremy Drury”; on 4 April 1616, the three men obtained a privilege for printing a book explaining an “instrument or table for cyfering and casting of accomptes” (Arnold Hunt, “Book trade patents, 1603-1640” in The Book Trade and its customers 1450-1900, London 1997, p.46). Soon thereafter, the partners fell out, and published competing manuals of instruction: Harpur entered his in the Stationers’ Register on 8 March 1617 (ESTC S103870), and Pratt on 21 June 1617.

Pratt intended that the book and instrument be “bound together in one (as most co[n]veniently they may)” and “therby made fit and portable companions of the pocket” (A5r), and in almanacs for 1618, the instrument maker Robert Limborough in Gutter Lane was advertising the instrument and Pratt’s book for sale together. Three versions of the instrument survive in leather bindings: one, now without the book, in the British Museum; another, accompanied instead by 33 sheets of manuscript instructions, in the Science Museum; and the third, an ivory plate 65 x 117 mm, accompanied not only by the book, but also by manuscript notes headed “Remembrances for the better understanding of Bills book”, in Cambridge University Library.

Another instrument survives outside a binding (National Museums of Scotland), while five copies of Pratt’s book survive without the instrument. Three press-altered states of the title are known. Only the copy in Cambridge (Syn.8.61.78) contains the engraved plate of the instrument found in the present copy.
