Neudrucke von Schriften und Karten über Meteorologie und Erdmagnetismus

Abstract

THESE reproductions in facsimile of classic papers in meteorology and terrestrial magnetism are attractive in appearance, and Prof. Hellmann's introductions and notes make them most instructive publications. No. 7 of the series contains papers of prime importance in the history of meteorological instruments, viz. the correspondence between Torricelli and Ricci on the measurement of atmospheric pressure, in which Torricelli announced the invention of the barometer (1644); and the paper “Saggi di naturali esperienze fatte nell' Accademia del Cimento,” in which the first continuous observations with the thermometer and hygrometer are described. This paper appeared in 1666 and passed through eight Italian editions, and was translated into English (1684), Latin (1731), and French (1754). Prof. Hellmann gives a list of the most important works upon the invention of the barometer, thermometer, and hygrometer, and adds some interesting historical notes.
