the parts in which he would divide the vessel, to 
1213629622, the cube of the parts contained in a 
French foot, the cube root whereof is 1066.666 ; 
and as 1000 to 1066.66, so is 15 to 16, and thus he

If instead of cylindrical vessels of capacity it 
should be deemed convenient to substitute vessels 
with either square bottoms or paralelograms and 
with sides at right angles to the planes of the bot¬

of the sides for the bushel and its subdivisions, and 
the wine gallon and its subdivisions, may be as in 
the following table. The bushel contains 2150
