PASCAL, BLAISE. Traitez de l'equilibre des liqueurs, et de la pesanteur de la masse de l'air. Paris: Guillaume Desprez, 1663. 2 engraved folding plates and one woodcut illustration in text. 12mo, contemporary calf, spine ends, joints and corners restored; minor marginal tear to plates. FIRST EDITION, of the first account of Pascal's law, stating that pressure in a liquid is transmitted undiminished in all directions. "Using the recently invented Torricellian barometer, Pascal had his brother-in-law climb the Puy de Dme in 1648 and watch the barometer level fall with the ascent, thereby demonstrating that air had weight... The relationship of barometric change and change in the weather was first outlined here." Dibner Heralds 143; Norman 1650; Sparrow Milestones of Science 157.
