Show Minerals mixed 32. §, Thefe things confidered, and other obfervations added here- unto, may poflibly give fome directions, not onlyfor the ordering and ufing, but even for the making, imitating and tranfmuting of Metals. Thusfar of Metals. 33. §. Iwill next give one or two Inftances of tryal upon Sulphurs. Andfirft Sulphur vive, with Aqua fortis, maketh an apparent Bulition, but itfome time, before it begins. But the facitious or common Brim- fine, maketh fearce any, if any at all. So that there is no fmall dif “ference betwixt them. 34. §. White and yellow Arfenick make no Bullition either with Al- kalies or Acids. Whereforethe f{trength of its operation onthe Body, lies more in a Sulphur thana Salts or ina Salt drowned in its Sulphure. 35. §. The afhes cither of Pit-Coal, or Sea-Coal, make no Efferwvefience with Alkalies or Acids, Whence the faline Principle is alto- gether volatile, and fublimed awaybythefire. 36. Lastly for Salts, And first of ail, Borax maketh no Effrvefcence nor any Fumes with Oyl of Vitriol or Spirit of Nitre. 37. §. Oyl of Vitriol and Nitre make fumes or fleams, thowgh no Effervefcence. 38. §. Green Vitviol, with Spirit of Harts-Horm, is foarcely moved. White Vitriol, with the fame Spirit, maketh a confpicuons huff. And Ro- Lea.IL with feveral Menftruums. 46. §. Oyl of Vitriol and Spirit of Salt, though both acids, yet make a flrong Effervefence, with noife and fumes. Which further conpa what was noted before, /c. that Spirit of Salt isa fubalkaline cid, 47-.§. Spirit of Salt Armoniac,with Oyl ofVitriol, makes an Efferwefcencefo extraordinary quick, and as it were inflantaneous,that nothing Jeemeth quicker. Whence it is probable, That if Gun-powder were made of Salt Armoniac, inftead of Nitre, or with both mixed together 5 it would be far ftronger, than any kind now in ufe. Minerals. 48. §. Andthusfar for Ihave only one Corollary to add, from the whole; which is, That whoever doth undertake the Natural Hiffory of a Country, (fuch as that the Learned Dr. Plot hath exceedingly well done of OxSordfhire ) the foregoing Method, feemeth fo eafie, cheap, and indeceitful, for the finding out and well diftinguifhing the natures ofall kinds of Metalls, Ores, Salts, Earths, Stones, or other fubterraneal Bodies 5 as cannot, I think, be fupply’d, but by others ofgreater difficulty and expence, man Vitriol a vehement Effervefcence. Whence the former is the leaft acid, and the latter the oft of al Whichalfo confirms what I faid before of the like natures of the feveral Azetals to which theybelong. 39. §. Salt of Vitriol, though a fixed Salt, and made by Calcinaticn, yet maketh no Effervefcence with the firongeft acid 5 but only with Alkalies 5 as may Le feen upon their mixture, but much better heard by hold- ing the mixture to one: ear. Hence, there are fixed Acids. Which further confirms what I have above afferted concerning the nature of Gold, {c. That the predominant Salt thereofisa fixed Acid. 40. §. Sal Martis, with Spirit of Harts-horn, maketh a confiderable huff. Hence it is much more acid than green Vitriol ; and is therefore a cooler body. Al. §. Alum andSpirit of Harts-horn make a plain Effervefcence. 42. §. Saccharum Saturni, with Oyl of Vitriol, firs not at all. With Spirit of Salt, buffs a little. With Spirit of Nitre much more. Hence the acid of the Vinegar, and not the 4/kaly of the Lead, is the predominant Principle. 43. §. Common Saltftirs neither with Spirit of Salt, nor with Spirit of Nitre; nor with Aqua fortis. But with Oyl of Vitriol it maketh a great Effervefcence with noife and fleams. Hence, even commonSalt, thoughit be not reckoned amongtt alkaline Salts, yet is far nearer in nature to that, than toan acid. Hence alfo the Spirit ofsalt isafub- alkaline A id, and of avery different nature from Oy! of Sulplur or Vitricl. 44, §. Salt Armoniac, with Spirit of Nitre, ftirreth not. But with Oyl of vitriol it maketh a great Effervefcence. Hence Spirit of Nitre 1s a fubalkalizate Spirit. 45. §. Oyl of Vitriol and Spirit of Nitre,though both acids, yet make 4 great Jmcak 5 greater than that which the Spirit maketh of it Jelf: Which confirms thelaft precedent Corollary. CHRP ASR als What may be obferved of the PARTS of Animals. NO proceed tothe feveral Parts of Avimals 3 as Hairs, Hoofs, Horns, Shells and fhelly Infeds, Bones, Filefh and the feveral Vifcera, Silk, Blood,Eges,Musk, Caftor, Gall, Urine, Dungs, Salts and Stones. 2. §. And firft of all, the Hair of a mans head, ; with Oyl of Vitriol, maketh xo Bullition at all. Nor yet with Spirit of Nitre. So that although it con- of volatile Salt; yet it feemeth either not to be alkaline, or elfe is centred in fo great a quantity of Oy!, that the acid men- firuum cannotreachit. 3. §, Hares Fur, withfpirit of Nitre, maketh, although a fhort, yet very plain Bullition and huff. ence the Hair, and therefore the Blood, of fome Animals, is fuller of Salt, at leaft of an Alkaline Salt, than that of fome others. And perhaps the Hair of fome men, as of Black's, may be fo full of sat, as to makea Bullition like Hares Fur. 4. §. The fhavings ofNails ftir not at all, either with Oyl of Vitriol, or Spirit of Nitre: only with the latter they turn yellow. But Elks Claws, with Spirit ofNitre, make a fmall and flow Bullition, 5. §. Horfes Hoof, with Oy! of Vitriol, ftirs not of weany hours. But with spirit of Nitre, allowing it fome time, makes a very plain Bullition, and huffs up very high. 6. $. Cows Horn, neither with Oy! of Vitriol, nor with Spirit ofNitre, maketh any Bullition, only turneth to a yellow colour. 7- §. Rams Hornftirs not mith Oy! ofVitriol 5 but with Spirit of Nitre, makes a fmall and flow Bullition. 8. gs |
