32 6 Capt. Kater's account of the re-measurement , &c. 
The length of the brass rule from this appears to be 
6,0063609 inches, which added to ,0012281, gives 6,00759 
inches for the diameter of the sphere; whence we have its 
solid content 113.5264 inches. 
It may now be useful to collect under one view the data 
furnished by Sir George Shuckburgh’s experiments, and by 
the preceding measurements.

From these data the weight of a cubic inch of distilled 
water in a vacuum at 62°, deduced from the cube, appears 
to be - 252,907 of Sir G. Shuckburgh’s grains. 
From the cylinder 252,851 
And from the sphere 252,907 
The mean of which is 252 ,888 
which is equal to 252,722 grains of the Parliamentary Stan- 
dard. 
It is not my intention to enter into a detail of the various 
corrections necessary in the computation of the preceding 
results, as they may be found in the Appendix to the Third 
Report of the Commissioners of Weights and Measures.
