Vions they may be better undcrflood, I have brought 
all the particulars hither. 
From what's afore faid I note, that from the com- 
mon drink cMtd Coffee^ there is little guod cm come 
from any part, but its Oyl^becaufe its other thin parts 
are evaporated, and its thick fubfides ; but its Oyl I 
fuppofe to be nutritive qt^afi Oyl, and warm qi^4fi a

our three Kingdoms fpend about one hundred Tun a 
• Year, whereof E»^U9id fpends about feventy Tun, 
which at fourteen Pounds a Tun (a middle price now 
a Days) will amount to 20586 Pound fterling, and if 
it were to be all fold ia Cofifee-houfes, it would reach 
treble 61740 Pounds, which at ten Pounds a Head 
will find employments for 6174 Perfons, although I
