I shall tell you at present, that the sowre Spirit of _Box_, not only would, as I just now related, dissolve Corals, which the other would not fasten on, but being pour'd upon Salt of Tartar would immediately boile and hiss, whereas the other would lye quietly upon it. The acid Spirit pour'd upon _Minium_ made a Sugar of Lead, which I did not find the other to do; some drops of this penetrant spirit being mingl'd with some drops of the blew Syrup of Violets seem'd rather to dilute then otherwise alter the colour; whereas the Acid Spirit turn'd the syrup of a reddish colour, and would probably have made it of as pure a red as Acid Salts are wont to do, had not its operation been hindered by the mixture of the other Spirit. A few drops of the compound Spirit being Shaken into a pretty quantity of the infusion of _Lignum Nephriticum_, presently destroyed all the blewish colour, whereas the other Spirit would not take it away. To all which it might be added, that having for tryals sake pour'd fair water upon the Corals that remained in the bottom of the glass wherein I had rectifyed the double spirit (if I may so call it) that was first drawn from the Box, I found according to my expectation that the Acid Spirit had really dissolved the Corals, and had coagulated with them. For by the affusion of fair Water, I Obtain'd a Solution, which (to note that singularity upon the bye) was red, whence the Water being evaporated, there remained a soluble Substance much like the Ordinary Salt of Coral, as Chymists are pleas'd to call that Magistery of Corals, which they make by dissolving them in common spirit of Vinager, and abstracting the _Menstruum ad Siccitatem_. I know not whether I should subjoine, on this occasion, that the simple spirit of Box, if Chymists will have it therefore Saline because it has a strong tast, will furnish us with a new kind of Saline Bodies, differing from those hitherto taken notice of. For whereas of the three chief sorts of Salts, the Acid, the Alcalizate, and the Sulphureous, there is none that seems to be friends with both the other two, as I may, e're it be long, have occasion to shew; I did not find but that the simple spirit of Box did agree very well (at least as farr as I had occasion to try it) both with the Acid and the other Salts. For though it would lye very quiet with salt of Tartar, Spirit of Urine, or other bodies, whose Salts were either of an Alcalizate or fugitive Nature; yet did not the mingling of Oyle of Vitriol it self produce any hissing or Effervescence, which you know is wont to ensue upon the Affusion of that highly Acid Liquor upon either of the Bodies newly mentioned.
