WILLIAMS, Jonathan (1750-1815). Thermometrical Navigation, being a Series of Experiments and Observations, tending to prove, that by ascertaining the Relative Heat of the Sea-Water from Time to Time, the Passage of a ship through the Gulph Stream, and from deep water into soundings, may be discovered in time to avoid danger, although (owing to tempestuous weather,) it may be impossible to heave the Lead or observe the Heavenly Bodies. Extracted from the American Philosophical Transactions. Vol. 2 & 3. With Additions and Improvements. Philadelphia: R. Aiken 1799.
8o (234 x 149 mm). Large engraved folding map (small hole along fold affecting image), uncut (light staining at end); 19th-century wrappers (light wear to spine and lower cover); cloth slipcase. Provenance: Harrison D. Horblit (bookplate; his sale Christie's East New York, 16 February 1994, lot 156).
FIRST EDITION, a scientific treastise advancing the idea that sandbanks could be discovered by using the thermometer. The folding map is of the Gulf Stream and its temperature at various locations. Benjamin Franklin's grand-nephew, Jonathan Williams, was the son of Jonathan Williams and Grace Harris Williams, daughter of Benjamin Franklin's sister, Anne. Williams along with his brother were sent to London in 1770 to complete their training and make contacts under Franklin's tutelage. Franklin was impressed by his diligence and the two remained close over the years. Williams lived abroad until his return to America with Franklin in 1785. In 1796 he became an associate judge in the court of common pleas, and gained a reputation as a scientist. He worked with his uncle on some of his later experiments. He also contributed to the Transactions of the American Philosophical Society, where he served at various times secretary, councillor, and vice-president. Evans 36722; Sabin 104300.
