Footnotes

  • John Towneley, author of the first volume, is recorded by as graduating MD from Leiden in 1681 and dying in 1704 (see the Ernest Bosdin Leech Manchester Medical Collection at the John Rylands Library). He was presumably a member of the Lancastrian family of Towneley Hall, near Burnley, possibly a son or nephew of Richard Towneley (1629-1707), the distinguished astronomer, meteorologist, inventor of the Deadbeat Escapement and correspondent of Flamsteed, Hooke and Boyle (whose eponymous Law was originally known as 'Towneley's Hypothesis'). As Roman Catholics, Richard and his brothers were educated in the Low Countries, a precedent clearly followed by the compiler of our volume. It is possible that the second volume shares the same provenance, although we can find no direct evidence pointing to this. The baseline upon which calculations are to be made in this second volume is 1650, with more specific dates cited of 24 November 1670 and September 1683.
