t*ceUkng etcedenglY hantrous, by rea1i  ot the ill ja-
lities of the Mercury4 is the Lot of the poor Indians. See
This Anmalgamatidn is continued for S or g Days: som'
add Limes Lead, or Tfti Ore, &c. to forward it; and ia,
tbme Mines they are obliged to ufe Fire.-To try whether
Or no the Mixture and Amalgamation be fuflcient, they
walh a Piece in Water, and if the Mercury be white, it has
* Ad its Effe&t, if black tit muft be further work'dc.
When enough, it is fent to the Lavatories, which arelarge
1afons that em pty fuccefflvely into one another.-The Patle
&c. being laid in the uppertnoff, the Earth is then wafh'd
from it into the reff by a Rivulet turn'd upon it ; an Indian
all the while firring it up with his Feet, and two other Indi-
ans doing the like In the other Bafons. See LAVADERO.
When the Water rins quite clear out of the Bafons, they
find the Mercury and Silver at Bottom, incorporated.-This
Matter they call Pella, and of this they form the Pinea's by
exprefling as much of the Mercury as they can; firfi by put-
ting it in woolen Bags and preffing and beating it ftrongly;
then by ftamping it in a kind of wooden Mould of an Oda-
gonal Form  at bottom whereof is a Brafs-Plate pierced full
of little Holes.
The Matter being taken out of the Mould is laid on a Tri-
vet, under which is a large Veif~l full of Water; and the
whole being cover'd with an earthen Head; a Fire is made
around it,
The Mercury filli remaining in the Mars is thus reduc'd
into Smoak, and at length condenfing is precipitated into
the Water, leaving behind it a Mafs of Silver Grains of dif-
ferent Figures, which only joining or touching at the Ex-
tremes render the Matter Very porous and light.
This, then, is the Pitiea's or Pigne's which the Workmen
endeavour to fell fecretly to the Velels trading to the South
Sea;i and from which thofe who have ventur'd to engage in
fo dangerous a Commerce have made fuch vaft Gains._
Indeed the Traders herein muft be very careful, for the Spa-
no Miners are errant Knaves, and to make the Pignes weigh
the mores make a Pra&ice of filling the middle with Sand
or Iron. See COMMEi6E, PIKEi, &C.
P 1 N E A L, P I N E A^L I S, in Anatomy a Nare which
Des Crwtes gives to a Gland in the third Ventricle of the
Brain; from its Refemblance to a Pine-Apple. See GLAND
and BRAIN.
This Gland he makes7 the Senforium, or Seat of the reafon-
able Soul. See SENSOxiUM.
Other Authors call it Conoides and Conarium., See CONA-
X1UM.

PIN IO N, in Mechanicks, an Arbor, or Spindle, in the
Body whereof are feveral or Notches, into which catch
the Teeth of a Wheel that ferves to turn it round. Or a
Pinion is a leffer Wheel, which plays in the Teeth of a larger.
See WHEEL.
In a Watch) &c, its Notches (which are commonly 4,
5, 6, 8, &c.) are calli'd Leaves, and not Teeth as ir. other
Wheels. See WArTCH.
Pinion of Report, is that Pinion in a Watch which is commron-
ly fix'd on the Arbor of the great Wheel, and which in old
Watches ufed to have but four Leaves; it drives the Dial-
Wheel, and carries about the Hand. See WATCIHW ORK.
The Quotient, or Number of Turns to be laid upon the Pi-
nion of Report, is found by this Proportion: As the Beats in
one Turn of the great Wheel, are to the Beats in an Hour;
fo are the Hours of the Face of the Clock, (viz. i2, or 24)
to the Quotient of the Hour-Wheel, or Dial-Wheel divided
by the Pinion of Report, that is, by the Number of Turns
which the Pinion of Report hath in one Turn of the Dial-
Wheel : which in Numbers is 26928: 20X96 : : 129. :
Or rather thus; as the Hours of the Watches going, are
to the Numbers of the Turns of the Fufy ; Co are the Hours
of the Face, to the Quotient of the Pinion of Report.-
If the Hours be I1, then I6 : I:: 2: 9. But if 24, the
Proportion is 16: 12 :: 24: 18.
This Rule may ferve to lay the Pinion of Report on any
other Wheel, thus: As the Beats in one Turn of any Wheel,
are to the Beats in an Hour; So are the Hours of the Face, or
1Dial-Plate of the Watch, to the Quotient of the Dial-Wheel,
divided by the Pinion of Report, fixed on the Spindle of the
aforeraid Wheel. See CALCULATION.

like other Ships; only that fhe is built with a round Stern;
the Bends and Ribs icompalling fo, as that her Sides bulge
out very notch. See VESSEL.
This Difpofition renders the Pinks difficult to be boarded;
and alfo ezables them to carry greater Burdens than o-
thems.
They are ofen utfedfor Store-Ships and Hofpital-Ships in
the Fleet.
