Description

Joly writes: 'In two papers read before the Royal Society, some three years ago, I described a “Method of Condensation” in calorimetry [see PP/9/12]. A number of experiments in support of the reliability of the new method are contained in those papers, as well as a description of such forms of apparatus as I had then. been, using. The apparatus, however, could not be said to be the result of a very prolonged study of the capabilities of the method, and possessed many defects, chiefly on the score of convenience in effecting the measurements. A continued use of the method since that time and its application to some exacting measurements have led to various alterations in the apparatus, so that, after many reconstructions, entirely new forms have been conferred on the instrument. I purpose to describe two new forms: a single calorimeter similar in type to the older instrument, but differing in construction; and a differential calorimeter, rendering possible measurements which could hardly be effected in the single type of instrument.'

Annotations in pencil and ink. Includes two diagrams of Joly's calorimeter.
