Anyone who has read C.S. Forester's "Hornblower" series of books will be acquainted with the periodical called the Naval Chronicle. Google has scanned in the complete collection of Naval Chronicle editions that span from 1799 to 1815, the Napoleonic War period. Links to them are available from https://en.m.wikipedia.org/wiki/Naval_Chronicle .
I started browsing through Vol. 14, 1805, https://books.google.ca/books?id=xnAMAAAAYAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false, with the intent of reading contemporary accounts of the Battle of Trafalgar...but got distracted by a paper on page 21 describing a method of sextant adjustment. It was written by a church minister, who lived about as far from the ocean as anybody in Britian could, and who used sextant observations to calibrate his gridiron-pendulum clock.
