    192, let thefe be added together and their Sum will be 967, alfotake the leffer Num¬ ber from the greater, and the Difference is 583 ; now thefe Numbers flhow, that to every 9671b. or Ounces of the Compound there mu ft be added 5831b. or Ounces of Spirit to make it Proof, becaufe then the Weight of Spirit will be equal to the Weight of Water; for 583 and 192 make 775* 28. And as nothing can be eafier than to weigh off any Number of Pounds or Ounces from any Compound, fo it may be immediately made Proof without the leart Difficulty or trouble in this laft Method, to any one that can but count the Divilions in a Line of equal Parts. 29. In the Ufe of this Scale, I would advife to have it parted on a Board,-and a Wire W R fixed over it on the Top, pa¬ rallel to the Lines on the Scale, and upon this Wire let a Line and Flu met S T be put, which may be moved to any Divifion of a Line, and then the Thread will fhow the Numbers in the other Linescorrefpond- ing thereto, and fo will render the whole Procels pra&icable with the utmoft Eafe. 1 .
