MR. J. W. CAPSTICK ON THE RATIO OF THE SPECIFIC HEATS 
§ 13. Isopropyl Chloride. 
The material used was obtained from Kahlbaum. On fractionating nothing came 
over below 35°'5, and almost all before the temperature reached 36°. The small 
residue was neglected. 
Table XXI. and hg. 14 give the results of the vapour density experiments, and 
Table XXII. gives the final values for the ratio of the specific heats.

§ 14. Isopropyl Bromide. 
The material was obtained from Kahlbaum, and boiled very constantly at 60 °. 
As the maximum vapour pressure at the atmospheric temperature is low, only a
