Description
Side view of a gravimetric calorimeter, designed by John Joly for experimental verification of the method of condensation applied to the determination of specific heat.
Illustration from the manuscript version of the paper ‘On the method of condensation in calorimetry’, by John Joly, Proceedings of the Royal Society, vol.41 (1886), pp.352-371. This item was lithographed as a figure for plate 6, accompanying the printed paper.
The author described the apparatus within the text of the paper: ‘The calorimeter consists of a nearly spherical chamber of very thin spun brass, 10.5 cms in diameter, made up of two hemispheres meeting on thin ground flanges. These hemispheres are carried by standards which slide upon the centre one of three rails…’
John Joly (1857-1933) Irish geologist and physicist was elected a Fellow of the Royal Society in 1892.
