by its weight to have retain'd four ounces of the Nitre, yet when it was carefully Lixiviated, even with scalding Water, the Laborant could get out but about 5 grains of Salt, that would pass through the Filtre: & that it self I judg'd by the Tast to be rather of a Nitrous Quality than of a Lixivial. With which it agrees well, that wealtered from 'it' did not find this Salt to produce a yellow Precipitate with the Solution of Sublimate, as Fixt Alcalies are wont to do.

To resolve a Question concerning the Cause & manner of Glaciation, we <took>replacing 'suspended' a small spherical Glass, <&> filld it with common Water, & then took off the slender stem, & clos'd the Orifice of it, that the whole vessel might be the more easily cover'd, by the Oyl of Turpentine wherein it was to be immers'd. †In deleted Inaltered from 'this' <this> Liquor (which we chose, as †much deleted not subject to freeze with an ordinary degree of Glaciating Cold) we suspended the foremention'd round Bubble, so as that it was every way cover'd with the Oyle, & then we plac'd <it> in our Frigorific Mixture, the <containing> Vessel; which was of Glass, that we might see what should happen, & but slender, that the Glaciation design'd might the more easily be made. And accordingly in a very short time we found, that thô the Ambient Oyl of Turpentine continu'd altogether fluid, yet the † deleted Water in the Globe was quite frozen, & had by its expansion <burst, & in many places crackt visibly crackt>replacing 'crackt' the little vessel that contain'd it.

Very fine Sulphur vive brought from Germany

{ounce} iv of Quicksylver, {ounce} ii of Salarmoniac, & as many of Flower of Sulphur, being well ground together were sublim'd in an Urinal fit for the purpose. This being broken after the Operation was ended, the elevated part was mix'd again with the Caput mortuum, & the Sublimation was reiterated. This was done once more, so that the Matter was sublim'd thrice in all. And at the second time there was added to the Mixture <of> fresh Sulphur & Salarmoniac {ana} {half} {ounce}. The Work being done, we had in the bottom of the Subliming Urinal
