Paper, 'On the measurement of the heat produced by compressing liquids and solids' by Cosmo Innes Burton and William Marshall The authors write: 'In the year 1885 Messrs. Creelman and Crocket (‘Edinburgh Roy. Soc. Proc.,’ vol. 13. p. 311), under Professor Tait’s supervision, performed a series of experiments on the heat produced by the compression of various substances. Their method was briefly as follows:— For the application of the pressure, the same apparatus which we describe and figure later was used. A thermo-electric junction of insulated nickel and iron wires was fixed between the leather washers and a sufficient length of wire coiled away inside the gun to allow the junction to be drawn out at the top and a specimen attached to it. Among the substances examined were glass, cork, vulcanite, glue, bees’-wax, and paraffin oil, the only pure chemical compounds being chloroform and ether. The following are some of the results obtained.' Annotations in pencil and ink. Includes one page of diagrams of experimental apparatus. Subject: Chemistry / Thermodynamics Received 10 June 1891.
