41. Then, by subtracting the numbers in the last threecolumns of the leads, from those of their correspondingbodies, the remainders will show the regular set of resistancesto the respective figures, as in the following table.—The co-lumn of numbers to be subtracted from that of the cylinder,which weighed 5 oz 1 dr, was deduced, by proportion, fromthe last column but one of the preceding table, which hasthe lead nearest of the same weight with it.
