Set 100 upon B, to 9-7.455, the Casks whole Content upon A, then against 15.5 upon 9, you have 15.105 upon A, and so many Gallons it will take to fill up the Cask; this subtracted from 97.455, the whole Content, there rests 82.35, the quantity of Liquor in the Cask which may otherwise be found thus, having set 32 the Bung.
