Bircher B 14220/21 - Wellcome II, 28 (cf.) - VD17 39:120069Y. - First German edition of the early work on physics by the French astronomer and physicist Joachim d’Alencé (also Dalencé). - The author attributes the invention of the thermometer to the Dutchman Cornelius Drebbel (p. 19). "Far more remarkable than this erroneous statement, however, is the fact that this little book is the very first to establish the true principle for designing a correct thermometer scale—namely, the principle of setting the thermometer successively to two temperatures that are constant by nature and dividing the interval ... into equal parts.” (Poggendorff). — Slightly discolored, text somewhat faded, scattered small wormholes. *
