[with] LIMBOURG, Joannes Philippus de. Observationes de Ascaridibus & Cucurbitinis, & potissimum de Taenia, tam humana quam leporina. Series: Philosophical Transactions of the Royal Society, Vol. 56, for 1766, 1767. 4to. pp. 119-132. One folding plate. Disbound. Fine. FIRST EDITION. John Michell was an English natural philosopher and geologist, whose work spanned a wide range of subjects, from astronomy to geology, optics, and gravitation. "Michell earned a permanent place in the history of stellar astronomy for two signal accomplishments: he was the first to make a realistic estimate of the distance to the stars, and he discovered the existence of physical double stars. . . Michell's published scientific work, which earned him election to the Royal Society in 1760, covered many subjects, including the cause of earthquakes (1760), observations of the comet of January 1760, a method for measuring degrees of longitude 'upon parallels of the Equator' (1766), and an independent discovery with Coulomb of the torsion balance (1784)."
