dung, and left to rot in a ditch for one winter : when this 

 mixture is taken out, two-fixlhs of broken crucibles, well 

 pounded and palfed through a fieve, are added : the whole 

 is tempered with urine and beat up on a ftone : it is then what 

 is called potee. 

 Formation of When it is to be ufed, a fufficient quantity is taken and 



^inued? "^^^^^ ^"°"g'' ^'^^^^ ^o ''' to make it capable of being laid 

 on with a bruQi ; forty coats of it are then laid over the wax 

 fucceffively, (care being taken that one coat is dry before an- 

 other is Jaid on), which altogether form a thicknefs of five 

 centimetres (2 inches.) The mold is then furrounded with flat 

 bands of iron, which crofs each other like net-work ; then, after 

 rendering ihe potee thicker, by adding earth to it, and hair that 

 has been well beaten, it is laid on over the former work with 

 the fingers, until the mold has attained the thicknefs of twenty 

 centimetres below and fixteen above (6 and 8 inches) ; after 

 which it is furrounded a fecond time with bands of flat iron.

 On the fecond day the wax begins to flow, and continues to 

 do fo for ten or twelve days; about half of it is loft. 



When the fire is extinguiflied, the work is left fome days 

 to cool ; then the broken bricks are removed, and before the 

 mold is buried, a coat of plafler, about half an inch thick, is 

 The moldbu- put over it, which is called the dianife. Then they proceed
