about 3 or 2 to 1, 1 to 1, and 1 to 2 or 3 parts by weight of 

 the two liquids, to measure the capillary height of each mixture 

 immediately after it was made, and then to measure the 

 density. In some cases where one of the liquids was very 

 volatile, and for any reason the level of the liquid in the 

 V-tube took longer than usual to adjust, so that the cork was 

 off too long, evaporation of the volatile ingredient altered the 

 proportions of the two ingredients a little from their original 

 values and altered the specific gravities a little. On account 

 of this occasional source of error, the values of pi and p 2 will 

 be given only to two figures, though measured to three ; as 

 pi +7^2= 1 j it is necessary to give only p 2 .
