i Have found by experience that this Mineral makes the 
Metal run moft freely, and givesk a fair golden Cou- 
lour. 
The Statue being caft, I take off the Mould and cut off 
all the little Ghanels ; all which both great and fmall are 
filled with Metal, which may be kept for further ule : In 
thele there is much more Metal than in tte whole Sta- 
tue ; for if the Statue be very thin, there muft be more 
and bigger Channels ; and fo the cheaper the the Statue 
the more weighty the Chanels and the more Metal re- 
mainihg. 
To know the quantity of Metal requifite for my in- 
tended work, I take a lump ofthc^ iame mixture of Wax 
and Pitch, with which I make the Mould of my Statue ; 
and having weighed it, I make a MW^^ upon it, and caft 
in the fame a lump of Me tie of the fame fize ; which I 
weigh and thereby compute the proportion of the weight 
of the Mettle and Wax ; then obferving how many 
pounds of Wax! ufe about the Figure and Chapels, I can 
calculate to a fmill matter how much Metal I need to 
melt. ' r 
This is my manner of cafting -ftatufes very thin, and 
which alwais fucceeded happily with me. Hitherto I 
have caft no ftatue above nine foot high, but I doubt not 
but I could, by the fame methods, caft one of any big- 
nsfs defired. And when we fhail be more at eafe from 
our ill neighbour the Ttirk^ I will taft at one fufion the Sta- 
tue of our Emperour Leopold. 1. fetting on Horsback, much
