Lapis Hematites maketh no Effervefcence atall either with Al halies or Acids. 6. §. Powderof the green part of a Magnet with Oyl of Vitriol maketh fome few bubbles, yet not viftble without aGlafs. But the powder of the black part of a Magnet, which is the faidftone fully perfed, ftirreth not with any acid. Neither doth the calcined Magnet. Hencethere is fome confiderable difference betwixt Jroz and the Magwet. 7- §. Lapis Lazuli, with Oil of Vitriol, and efpectally with Spirit of Nitre, maketh a confpicuows Bullition, Henceits Cathartick virtue lyeth in an Alkaly. For whichreafon it is alfo appropriate, in like manner as Steel, to the cure of Hypochondriacal Affedtions 3 originated from fome kind of fermenting Acid. 8.

Reéfified Spirit of Wine, both with Spirit of Nitre, and with Oil of Vitriol, feverally, maketh a tittle Ludation. Which argues, that thereis contained, even in this Spirit, fome portion ofa volatile Alkaly. 25. §. Spirit of Wine, and double Aqua fortis, as the firongeft is called, make an effervefcence fo vehement, as plainlyto boil. 26. §. Befides the vehemency hereof, there is another Surprising circuntftance. For whereasall other Liquors which make an Effervefcence together, will do it in any proportion affigned, although but one drop toa thonfand: thefe two, fc. rectified Spirit of Wine and Aqua fortis, re quire a certain proportion the one to the other. Forif, fuppofe, into fix drops of Spirit of Wine you put but two or three of Aqua fortis, they flir no more than if you put in fo much Water: but drop in about fever or eight drops of Aqua fortis, andthey prefently boil up with wery great vebe- a Whereto thofe that ufe them, are to have regard. 4. §. contrary toan acid; as experience fhews in their efficacy againft the teft. Aguafortis, and Oyl of Vitriol being pouredfeverally upon ano- ther fealed Earth, which was vended by the name of Terra Lemnias they both made a very confiderable Effervefcence herewith. Whenceit appears, That there is no {mall difference in the nature, and therefore the operas tion of Bolus Armena and Terra Lemnia. As alfo, betwixt the fealed Fallers Earth, doth not ftir it, or canfe the leaft |) Bullition. Nor upon yellow Oker. Nor upon the ~. Oker which falls from green Vitriol. The fame Oy! of Vitriol and Spirit of Harts-Horn poured feveral ly upon Bolus Armena of two kinds, and upon one kind of Terra figillata , ftir none of hem. Hence Bolus's are the Beds, or as it were, the Materia prima, both of opacous Stones, and aetals into which the faid Bolus's are tranfmuted, by being concentred with divers kinds ofSalts and Sulphursy which fucceflively flow in upon them. 2.8; And with Oyl of Vitriol very confiderably. But Lapis Cala- minaris with Oyl ofVitriol growsflark; as the powder of Alabafter doth with water. With Spirit of Nitre it maketh a little Bullition, and quickly. But with Aquafortis, agreat ones beyond any of the Stones above named. Hence both Tuity and Calamy are Ophthalmicks from their Alkaly. Which is alfo confirmed, fromthe efficacy of fome Alfalies of the like ufe, Hence alfo Calamy {eemeth to partake fomewhat of the nature of Silver : as by tryal made upon that alfo, will hereafter better apear. * 10. §. Chalk and Oil of Sulphur or Vitriol make as flrong an Effer- wefcence as any ofthe reft. Whenceit is fometimes well ufed again{t a Cardialgia. 11. §.
