[PHYSICAL SCIENCES and METEOROLOGY]. LABAT, François de, Chevalier de Vivens (1687-1780) Rises & falls corresponding to the barometer, reflux of air. 11 pp various formats (s.l[Bordeaux]), 1745,1747,1748,1750 and 1751. Autograph annotations and corrections. Central fire, variations and studies based on barometer; It is certain that air must condense of its own accord, i.e. by its own weight, as soon as no movement acts in any direction to [ ] from one side & the other [ ]; The most remarkable observation I have made so far is the one I am about to report. On December 15, 1748, the barometer was at towers at the highest degree, at 28 inches 5 lines, where it remained for two days, the wind at 50 prevailing, the sky overcast, the air foggy & rainy [ ]. Interesting manuscript on the effects of steam. 6pp in-8 (s.l. [Bordeaux]), 1746. Autograph annotations and corrections.
