PROFESSOR W. RAMSAY AND DR, S. YOUNG 
The temperature 175° was maintained by jacketing the experimental tube with 
aniline; methyl salicylate was used for the temperatures 185°, 195°, and 220°; and 
bromonaphthalene for 250° and 280°. It should be mentioned that fresh samples of 
aniline and methyl salicylate, carefully fractionated from impurities, were employed.

Mean, 23,763. 
The mean of previous determinations of vapour-pressure at 175° is 20,189 ; and at 
185° 23,623. Considering that the samples of ether, aniline, and methyl salicylate 
were different, and that the gauges were refilled, the agreement is satisfactory.
