Series III, 
34. The amount of alcohol used for the determinations of which the results are 
given above was too large to admit of values at lower temperatures; a fresh portion 
was removed, and the weight of the remainder was ascertained by determining the 
value of P. Y. at a temperature at which it became constant at the highest volumes. 
This temperature was 130°, and the mean value obtained for P. V. was 950’8. From 
this the weight of alcohol was calculated to be 0'001747 grm. 
The following measurements were made :—
