How you may be Arithmeticall skill, know how much of euery kind of mettall any brasse peece of Ordinance containeth.

Question.

Euery Gun-founder doth commonly vse for euery 100 pound weight of copper, to put in 10 pound weight of lattine, and 8 pound weight of pure Tinne: I demand how many pound weight of euery of those mettals is

Page 34

in a Culuering of 5600 pound weight?

Resolution.

To answere this or all such like, I ioyne all the seue∣rall mixtures together, and they make 118 pound, which I reserue for my deuisor. Then I multiply the weight of the peece by euery mixture seuerally, and there ariseth of the 100 weight of copper being the greatest mixture, 560000, the which sum is to be deuided by the deuisor common (to wit, 118 pound) and the quotient is 4745 pound and 90/118 partes of a pound: so much copper is in the said peece. Now to know how much latin is in the same, I multiply the whole weight of the peece by 10 the second mixture, and the product is 56000, which number deuided by the deuisor common, the quotient is 474 pound 68/118: so much latin is in the same peece. And lastly to know how much Tin was in the same peece, I multiply the weight of the peece by 8, ariseth 44800, which deuided by the deuisor 118, the quotient is 379 78/118: and so much Tin was put into the said peece.

Now to proue the worke if it be truely wrought or not, I adde all the 3 quotients together, and because they doe all make the true sum of the whole weight of the peece according to the proposition, I affirme the same to be truely wrought.

The Gun-founders do hold and affirme,* 1.1 that the lat∣tin doth incorporate, and causeth the peece to be of a good colour, and the Tin doth strengthen and bind the other mixtures.
