ALL Minerals arc produced by cryflallization, except the undluons 
Sulphurs. 
The extraneous matters commonly contained in Minerals, are 
Salt, Sulphur, Mercury. 
Minerals are to be dillinguiflted by feparating from them their ex- 
tranepus connediions, and then reducing them to their genera 
and appropriate charadj-ers; for, as in plants, they are to be 
found in their internal frncfification. 
S-M-TS dilTolved in water, are cryftallized by a diinuniticn of the 
vehicle, by quiefcence, and cold 
They are many-fided, and their cryllals fltow that ail Salts are from 
plane and right angles. 
The hgure of Cryjlals in the fame (Uenus are often in fome mca- 
furc changed, but not without the inttniions of nature, wlio 
never afts without i'ufficient caufe, in whole agency nothing is 
fuperfliious, nothing deficient; this the knowledge of fiitiite 
ages will difclofe, and the niimerons oblervaiioi s wandering 
through the dark reeefl’cs of nature will at length find out her 
ways. 
Stony Cryjlals I have retained according to their figure, as far as 
invelfigations have hitherto extended. 
That Earth can be cryltallized without fait by the htiniid way, I 
will give credit to when I (hail have feen it; the dry way i.s 
totally diftindt. 
SuLTHURS in ignition give out flame and finoke, are dilTolvcd in 
oil, for they abound in lalt, and are dccompofite. 
The unituous agree in many refpedts with the relitis of vegetables, 
and are probably of vegetable origin. 
The mineralized a faline metaljc combination. 
Metals give a (hining opake regulus, fluid in ignition; except 
Molybdamum which is as yet obfetire. 
The tranfmutation «t Metals, hitherto concealed in the temple of 
Vulcan, is to be regardeil as one of the fecrets of nature.; and 
from very few parents are produced a numerous offspring. Mars 
was altogether polygamous.
