is reprefented by GH. On which fide, the more one 
view'd it, the more (hould one be perfwaded that the 
many fmall fhining Particles were certainly Metallin ^ but 
when I brought it to the Fire, and endeavcur'd as much 
as I was abl€ to keep the Smoak to2;cther5 it appeared 
plainly to me to be nothing but Sulphur, which was not 
only oiaoifeft by the fmell of it, but that which was 
drawn off was of a yellow Colour, jufl: as Sulphur ap- 
pears to our naked Eye, 
"Now thart Fig. I. ABCDEisa part of a real Snail 
is clear to me, but how, and after what manner the Sul- 
phur gets into the Horn, we can only guefs. My opinion 
of the matter is this : The Snails and other things that are 
found upon the Mountains of Swifferland^ and which are 
fuppofed to be changed into Metals, have lain, and do 
ftill lye where a great quantity of Sulphur h fhut up in 
the Bowels of the Earth 5 and that Sulphur, by a Sub- 
terraneous Heater Warmth being rendered Fluid, mounts 
upwards in exceeding fine Particles like Fire, rnd fo infi- 
Buates itfelf not only into the inmofl: parts of the Si^ail- 
fliellj where, according to all appearance, the Snail itfelf 
is almofl: confumed, but alfo into the Pores of the Horn 
or Shell, and is there fixt and coagulated, fo that the 
whole Snail is converted into a Sulphureous Subftance. 
This may feem ftrange to fome people, but thofe that 
have deal.t in Sulphur, and know into what an un/peak- 
able great numbej of fmall parts it can be divided by 
Fire, ^ they can eafily conceive into what a number of 
Bodies, Sulphur, being put into a Fluid Motion, can 
infinuate itfelf in fome Ages 5 for, according to the opi- 
nion of the Learned Mr , as I have been infornfd, 
thefe Snails, and other Teftaceous Animals, which are 
found in the High Mountains of Swifferland, have Iain 
there ever fince the Deluge h and fo many of them by 
length of time are turned into Metal^ or rather, accord- 
ing to my Hypothefis, are moftly Sulphur,
