which Is ufed to defign on Paper, andeafily wipes out with 
Bread, but it is not the fame : this colour I mix with Wa- 
ter, and daub all over the Core^ becaufe the Metal is found 
to run freely upon it. There are other Subftances pro- 
per for this purpofe, but I have always made ule of this, 
elpecially for thin Statues. This done, I lay on upon the 
Core as much yellow Wax mixed with Pitch or Rofin as 
will make the thicknefs of the intended Statue, which I 
form in the Wax with all the exaftnefs pofRble. 
Here note, that the Particles of Metal mentioned to be 
fet into the Corcy to keep it at a diftance from the Mold 
muft be fb fet as to fall in with the furface of the Wax ex- 
aftly : and that the reafon of mixing Pitch or Rofin with 
the Wax is, becaufethat when it is burnt out, it makes 
a great fraoak, and that fmoak adhering to the Mold occa- 
fions the Metal to run more freely: as I have experienced it. 
Next I put all over upon the furface of this Statue of Wax, 
little pieces of Wax which I call the little chanels ; in the

done, I cover the Core and wax all over with the fame fort 
of Clay, that will endure the Fire without cracking ; and 
fo I have ray Concave Statue or Mould made. Upon this 
Hay the great Chanels marked ^,^.. both upright 
and tranfverfe, formed likewile in Wax, and placed ac- 
cording to Jiidgmenr,. foas beft to receive the ends of the 
little Chanels c.cc.c. c. for the rrK)re eafie diftribution 
of the Metal. Thefe great Chanels muft all meet at the 
top of the Statue, lb as to come out by one hole, as at £, 
where the Metal is to be poured in it is dfo necefTary to 
have a Ch uiel or two to let out the Air as the Metal en- 
ters, as\rho(e marked/./; and there muft be a hole or two 
left at the foot, as^.^, where the great Chanels and waxr 
en Statue joyn ;, and whereat, wheathe Mould is burnt, 
the wax as well of the Statue as of the Chanels may run
