or elfe you will loofe a great deal of the Mercury^as happened, 
itfeems, to our Authorj when his Prince, being impatient of 
delay, commanded the water to be poured out before 'twas 
time : For the Mercury, being by lb ftroog a fire rcfolv'd into 
Atoms^is to be coagulated again by Cold. 
This Mercury ot Antimorjy our Author glorieth in, as ha- 
ving prepared and handled it with his own hands, and feen ic 
with his own eyes, after the fioiflitdiftillation,rnnning in the 
bottom of the veffel. Neither doth he care, if any do ftill call 
it a Non- Entity i or if any unwary Laborants be unfuccefsful 
in th^ operation. It is (ufficient to him, that he hath nothing 
alledgedj but what he hath tryed himlelf, and candidly de- 
fcribed. He wifheth fuch Operators to coofider, how many 
things there are to be obfervd before and in the operation, 
and even after it, if you will be certain thereof* Which he 
faith may plainly appear even by the Operation of the Tartar 
alone^ forafmuch as all Tartar is not equally good, and himfelf 
hath met with great diverfity of the fame: Befides which great 
care is to be bad of the Fermentation it fcif of the Tartar 5 for 
if it be not duly made, the Tartar will not be refolv'd per mini' 
ma ^ nor will the Grapes be reprefented in that natural fliape 
they ought to bejnor will all the Salt3(which is the main thing) 
be volatilized* Further,if perhaps the fire be exceffive during 
the Diftillation^ much of the Volatil Salt will be burnt up, and 
it will yield a ftrong fmelling Spirit. 
Having difpatch't th'Sj the Author lubjoyns an accomptjhe 
met with among his Papers, of another way of Operation of 
Grinding of Gold 3 which though he have not yet tryed, yet it 
feeming to him very likely to fucceed, he (cruples not to com* 
municate a4fo. Theioftrument^to beufed therein, he defcribes 
thus.
