not but it will be agreeable to the Society ^ and the. 
rather, becaufe the Subjeds from which I have taken

Society, and fubmitted to a Re-examination, if de- 
fired. 
The Meafure which I have here ufed is the 113th 
Part of an Inch. 
I have taken the Triple of the Diameter for the 
Periphery, and computed the Area by multiplying 
the neareft whole Number to J of the Diameter 
into the Periphery. Though this Method is not fufw 
ficiently exad to (hew the real Contents of Circles, 
yet as my Defign here, was ^ only to find nearly the 
relative Contents of the feveral' Vefiels, I have chofe 
to avoid embarafling the Sums with Fr^dions.
