ALL Minerals are proclucc^l by crylUHizatlon, cxi^ept the unctuous 

 Sulphurs. 

 The extraneous matters comnionly contained in Minerals, arc 



Salt, Sulphur, Mercury. 

 Minerals are to be di(lingui(Ticd by feparating from them their ex- 

 traneous connections, and th^n reducing them ip their genera 

 and appfopriate chara^ers; tor, as in plaiiis, they arc to be 

 found in their internal lru6lification. 



Salts dilTolved in water, are cryftallizcd by u uimiipitic;!! of th? 

 vehicle, by quiefcencf, aiid cold 



They are many-pdedy and their cryfUls Ihpvv that all S^lts arc from 

 plane apd right angles. 



The hgure of Cryjials in the fams Genus are often in fomc mea- 

 fure changed, but not withovit the inuqiions ot natun., wiio 

 never a6lb without fuflicieni cauf*.-, in whoija-^tncy noiiiiogis 

 fvpertiuous, nothing dclicicnt; this the knowledge of future 

 ages will difclofe, ai;d the numerous obfervatioi.s wandering 

 through the dark receiTcs of nature will at length liiid put her 

 ways. 



Stony Cr\Jiah \ have retai^itd according to their figure, as far as 

 inveftigations have hiiheno extended. 



That Earth can be crylbiilized without fait by the humid way, I 

 will give credit to when I l^all have feen it; the dry vv^j is 

 totally diftinCl. 



Sulphurs in ignition give put flame and fnioke, are dilfolved in 

 oil, ior they abound in lair, and are decpmpoiire. 



The unSfuous agree in many refpc6ls with the ichns of vegetable^, 

 and are probably of vci^eiabie origin. 



The tninfralizffdh^ve a fi^lme ixittalic combinati(\n. 



Metals give a fhining opake regulus, fluid in ignition; ej^cept 

 Molybda^num which is as yet obfcure. 



Th^ trarif mutation of Metals, hitherto concealed in the temple of 

 Vulcan, is to be regarded as one of the fecrets of nature ; and 

 from very few parents are produ,ced a numerous offspring. Mars 

 was altogether polyganaous. 



Plantlna in fpecific gravity is from 29 to 22,oco. its fufion is 9. 

 amalgamation o. colour white, and is lolubli^ ojdy by oxymui 

 riatic acid. 



Goldh in fpecific gravity ^9,640. its fufion is 6. amalgamation i. 

 colour yellow, in confidence moft malleable and dudtile, is with- 

 out found or mute, and is foluble by the oxymuriatic acid. 



Silver is in fpecific gravity 11,091. in fufion 5. in amalgamatioa 

 2. in colour white, in confiltence moft malleable and dudiile, is 

 fpnpfous, and is foluble by the r\itrous acid.
