MR. H. J. CHANEY'S RE-DETERMINATION OF 
As the cubic contents of C = 572 - 80365 cubic inches, the mass of one cubic inch 
of distilled water (A 0‘998881) at 62° Fahr., B. = 30 inches, has been taken as 
252'267 grains. 
Diameter and Height of Q. 
The diameter of Q was measured at 25 different points, each measurement being 
the mean of three readings. The method of Fizeatj was followed, the true distance 
between the “ points” (p — p) being ascertained after the diameter of Q had been 
measured.

At t. 62° the true distance been p — p' was found to be 3’08234 inches by the 
3-incli steel measure (2'999749 inch). Hence at 62° Fahr. the diameter of Q was 
taken at 3 08399 inches.
