Kl.-4°. Mit 1 Kupfertafel (linker Rand knapp beschnitten, dadurch minimaler Bildverlust). 40 (recte 38) SS. Zeitgenöss. Buntpapier-Broschur. Erste Ausgabe der seltenen Dissertation über Entwicklung, Bau und Funktion von Thermometern.- Johann Melchior Verdries (Gießen 1679 - 1735) war Arzt und Professor für Physik und Medizin in Gießen. Er studierte ab 1694 in Gießen, Jena und Halle Medizin, mit der Lizenz 1702 in Gießen. Darauf reiste er zu Studienzwecken in die Niederlande und wurde 1707 in Medizin promoviert. Im selben Jahr wurde er außerordentlicher und 1710 ordentlicher Professor für Physik in Gießen. 1714 wurde er außerordentlicher und 1720 ordentlicher Professor für Medizin in Gießen und 1727 Rat und Leibarzt des Landgrafen von Hessen-Darmstadt.- Papier leicht gebräunt und stellenweise etw. braunfleckig.

(Paris, Jean Boudot, 1704). 4to. Without wrappers. Extracted from "Mémoires de l'Academie des Sciences. Année 1702". Pp. 155-174 a. textillustrations. First appearance of this paper in which Amontons describes his invention, construction and function of his air thermomer. He thus improves on Gallileo's design by using air pressure instead of volume. The paper is the earliest study in this field, and Amontions concludes "that unequal masses of air under equal weights invcrease equally the force of their spring for equal degrees of heat" Fifteen years later Gay-lussac performed the same experiments with better technique and results - the Gay-Lussac laws.The paper "contains Amontons' account of the first thermometer with which temperature was measured by the pressure of air."(Magie "A Source book in Physics", pp. 128 ff.)."His first scientific production was a Hygrometer in 1687.The other was an air thermometer independent of the atmospheric pressure. Air occupied the top of one of the branches of a U-shaped tube, and by its dilation it pushed down one of the mercury columns so that the other end ofthe branch formed a barometric chamber."(DSB I, p. 138 a).Parkinson "Breakthroughs", 1702 M).
