‎---- EDITION ORIGINALE ---- EX-LIBRIS manuscrit de l'époque "MORIN" sur la page de titre ---- DIBNER N° 143 : "In this small posthumous volume, Pascal correlated hydrostatics and aerostatics by simple demonstrable relationships and banished the myth that "nature abhors a vacuum". Using the recently invented Torricellian barometer, Pascal had his brother-in-law climb the Puy de Dome in 1648 and watch the barometer level fall with the ascent, thereby demonstrating that air had weight, like, he stated, a blanket of wool 20 or 30 fathoms high. The relationship of barometric change and change in the weather was first outlined here. In fluid mechanics Pascal enunciated his law that pressure applied to a confined fluid is transmitted equally thru the fluid in all directions and that it acts upon the confining surfaces at right angles and with equal pressures in equal areas" ---- EN FRANCAIS DANS LE TEXTE N° 101 ---- Norman N° 1650**3980/ARB3-3985/MAI‎
