ral Gentlemen, who view’d them with great Attention 5 
among the reft there was a Jeweler, who Teem’d to be 
ftruck Dumb at the fight, and laid, that it would be im- 
poftible for any five Mouths to declare the Wonders that 
he had Teen. 
Now, to be more Cure that the abovementioned coa- 
gulated Chryftalline Particles were real Silver, (tho I 
made no doubt of it my (elf) fince Salt Petre and Cop- 
peras, from whence Aqua Fortis is Diftilled, do never 
produce fuch Chryftals, at leaft in all Obfervations that 
ever I made of them $ I took fome of thofe Chryftalline 
Particles, and laid them upon a piece of Wood-Coal, 
and with the flame of a Wax Candle, which I blew upon 
them, put them into fuch a Fufion, that they prefently 
became round Globules, which Globules were plain vifi- 
ble Silver. 
Hereupon I Cent for a Painter, who in his Youth had 
alfo been a Silverfmtb, and caufed him to view thofe 
Chryftalline Particles thro a Microfcope, and when I had 
told him what it was that he had feen, he burft out in- 
to this Expreffion, Good God ! What Wonders are thefe ? 
I made him draw one of thofe Silver Particles of the 
fame fize with thofe, whereof I had difeover’d great mul- 
titudes in my firft Obfervation $ fee Fig. 1. between A 
and B. 
As alfo another Chryftal Particle reprefented by Fi- 
gure 2. C.D. 
Figure 3. EFGH. (hews you another Chryftalline Par- 
ticle as it lay juft oppofite to the fight, wherein you might 
obferve at EG the beginning of the flanting of the fix 
(ides which end in the points of F and H. 
Fig. 4. 1KLM is likewife a Silver Particle turn’d into 
Chryftal, in which one would imagine that one faw be- 
tween K and M (as it is deferib’d at N) a Quadrilateral 
plain or flatnefs, and that IN and NL, parts of the little 
Chryftal, were alfo flatifli y and this appears more vifibly
