London: J. Dodsley, 1793. 5th Edition. Hardcover. Very Good Condition. Item #373234

21 pages. This 1765 article, published in The Annual Register, provides a detailed account of John Harrison's groundbreaking work in solving the longitude problem at sea through the use of artificial time-keepers. Harrison, an English clockmaker, developed the marine chronometer, a device that allowed sailors to accurately determine their longitude while at sea. His invention was crucial for safe navigation, reducing the risk of ships becoming lost or wrecked due to miscalculations. The article outlines the proceedings and debates surrounding Harrison's work, including his struggles with the Longitude Board, which was reluctant to grant him the full 20,000 prize promised under the 1714 Longitude Act. Despite proving the accuracy of his time-keepers, Harrison faced political opposition and bureaucratic delays before finally receiving recognition for his achievements. Published at around the same time that Harrison's book of a similar title was published, this contemporary 21 page account quotes Harrison extensively and represents the opinions and ideas regarding navigation from the perspective of the time. The whole volume extends to around 600 pages. Bound in modern, but not recent, brown buckram, with a contrasting black leather lettering piece, gilt title. Library label to the endpapers, stamp on first blank, and label to reverse of the title page. The first blank has a hand note stating "Given by Lt.Col. A.R. Hurst". Hurst has served with the Royal Field Artillery in the First World War. The whole volume is very clean, with bright pages, very firmly bound, and in attractive condition. Size: 13.5 x 21 cms.
