Modern three-quarter leather bound marbled boards with gilt tooled label on spine, Introduction, 280 pages, Appendices, Conclusion and Errata. Printed for the author, London 1808.
A most important work regarding this period in precision horology, and the London trade in general. It provides a highly personal and often antagonistic account of his affairs concerning John Arnold, Nevil Maskelyne, Thomas Wright, Thomas Hughes, Miles Brockbank, James Peto, etc. Echoing his poor behaviour towards Thomas Mudge, Sir Joseph Banks, then President of the Royal Society and a Commissioner on the Board of Longitude, does not come out well, whereas Maskelyne, the Astronomer Royal, appears to have been much more fair in his dealings with Earnshaw.

With the usual browning and publication creases to some pages and with an archival tape repair to a small tear on the title page. The Errata page with the usual addition (in Earnshaw’s hand?) “for Crosby always read Crosley”
