![[BEAUFOY, Henry Benjamin Hanbury]. Journal kept by H.B.H.B. during an aerial voyage with Mr. James Sadler, Sen., from Hackney, Middlesex, to East Thorpe, Essex, five miles from Colchester, August 29, 1811. London: G. Woodfall, [1811]. 8o (200 x 130 mm). Folding table. 39 pages, disbound. FIRST EDITION. A very rare privately printed account of an early balloon ascent. Beaufoy's observations are of a scientific nature, rather than merely narrative or lyrical, and hence distinguish themselves from other aerial adventures of the day. James Sadler, an experienced ballonist, permitted the use of watch, barometer, thermometer, electrometer and other devices for study.
