greenifh colour, ftrewon it Aunpigmzntum finely pow- 

 derecl, as rriuch as will lie on a Shilling to i2 pound of 

 Lead. Then liir them together, and the Auripigmen- 

 turn will flame. 



Your ladle ought to have a Notch on one fide of 

 the Brim for the more eafie pouring out of the Lead » 

 and the ladle ought to remain in the melted Lead, that 

 the heat may be agreeable to it, to prevent all incon- 

 veniencies which may happen through excefs of heat 

 or cold. Then try your Lead by droping it into wa- 

 ter. If the drops prove round, then the temper of 

 the heat is right •, but if the Shot have Tails , then 

 there is want both ot heat and Auripigmentum. 



Then take a Copper-plate about the fizeofa Tren- 

 cher-plate, with an hollownefs in the midlt about three 

 inches compafs, with about forty holes bored accor- 

 ding to the fize of the Shot you intend to call. The 

 hollow bottom (hould be thin, bat the thicker the brim 

 the better, becaufe it will longer retain the heat. Place 

 it on an Iron frame over a Bucket of water, about 

 four Inches from it, and fpread burning Coals on the 

 plate to keep the Lead melted upon it. 



Then take up fome Lead and pour it gently on the 

 Coals on the plate, and it will force its way through 

 the holes into the water, and form it felf into Shot. 

 Thus do till all your Lead be run through the holes of 

 the plate : obferving to keep your Coals alive , that 

 the Lead may not cool, and fo (lop up the holes. Whilit' 

 you are calling your Shot, another perfon may catch 

 fome of the Shot with another Ladle, placed four or 

 iive inches ( underneath the bottom of the plate ) in 

 the water, and by that means you may difcern if there 

 are any defcdis in your procefs, and redifie them. 



The chief bufinefs is to keep your Lead in a juft de- 

 gree cf heat, that it be not fo cold as to fill up the holes, 

 nor fo hot as to make the Shot crack. To remedy
