gave lecture-demonstrations on physics and also supplied all the instruments needed to constitute a pesonal physics cabinet,his instruments being found, for example, in the collections of Charles of Lorraine (d. 1780) (1). His standard course was composed of eight sessions, but he also offered private courses when and where desired by the client. C.1782 he developed a portable barometer with corrections for the effects of heat and cold on the mercury (based on William Roy’s observations as published in the Philosophical Transactions). At about the same time he produced a reliable copy of Alexander Cumming’s forecasting barometer which he described briefly in his Observations. A cistern barometer with overflow adjustement by Bianchi is known (2).
