⁂ Rare, with no copy traced at auction and only a few other works by the author making appearances. Bushell (c.1593-1674) was a servant and secretary to Sir Francis Bacon. He was granted mining rights in Wales, revitalising the mines exploited and then left in poor condition by Sir Hugh Middleton, from which silver had been extracted and sent to the Royal Mint in London. He established a local mint at Aberystwyth in 1637 which issued various denominations of silver coins. During the Civil War he was on the Royalist side and held Lundy Island for the King, which was not surrendered till 1647. He is buried in the cloisters of Westminster Abbey.
