A ReUthn 
Concerningthe Quick-filver Mines inVmM ^ communicated hj 
Dr. Edward Brown 5 cen-ftrming as mil the Ammft for^^ 
merlj given of that (uhjeSi^ in Numbc 2. ^ ^he/e Tranfa^ai- 
c^Sy as enlarging the fame with fome Additions. 
THe Town of idriaM the County of Goritia and Province of 
Friuli^ is feaced lowi and enconipafs'd wich Hills on all 
fides. A River of the fame name runs by it, which although 
Leandro ternfis it fuferbisfimo fume £ idria^ yet I found fmall 
and (hallow at the time when 1 was there 5 though upon plenti- 
ful Raine it proves fufficient to convey down the Firr-Trees 
and other Wood required in the building of the Mines, and alfo 
for Fuel required in the fervice of them : And to this end there 
is an handfome work of Piles raadefloaping athwart the River 
(after the fame manner as I obferv*d in Netvfol in upper Hun* 
gary crofs the River Grany) to flop the Trees, which are cut 
down, and caft into the River above this place. 
What is chiefly confiderable in this Town, are the ^ick-- 
fher-MincSy very well known to the Neighbouring parts, and 
exceeding ufeful to many at greater diftance. 
The entrance into thefc Mines is not high, or upon an Hill,as 
in many other Mines 5 but in the Town it felf, whereby they arc 
fomewhat the more troubled with Water, againft which they are 
provided with many excellent Engins and Devices, as at other 
deep Mines. The deepeft part of the Mine from the entrance,is 
between 120 and 130 fathoms. 
Of the Quick- filver of this Mine they make two forts : The 
one they call lungfran^^ that is, r/r^/VQjiickfilver^ theotheri 
//i/;^ Quickfilver. r/>^/;i-Mercurj they call thatj which difco- 
,vers it felf without the help of Fire 5 and is either plainly to 
feen in the Ore> or falls down in little drops in the Mine, arid 
fometimes ftreams out in good quantity 5 as about fevenycais 
agoe it ran out of the Earth at firfl in a ftreame as fmall as a 
thred, and afterwards as big as a pack-thred^but ccas'd in three 
or fourdayes.
