Paper, 'A new contrivance for taking levels' by J T [John Theophilus] Desaguliers

Reference number: CLP/18ii/16

Date: 1724

Description

Desaguliers writes: 'That the air thermometer is also a barometer, has been observ'd long ago; and, because the liquor in it will rise and fall, as well by the change of the weight of the air, as by the air's rarefaction by heat and cold, this instrument has no longer been made use of as a thermometer, and, in its stead, spirit of wine thermometers, hermetically sealed, have been us’d ever since.' He describes the designs and uses of several barometers. Includes two pages of figures of barometers.
