FOOTNOTES:

[1] Those who have the curiosity to see a more particular account of the Crystallization of Neutral Salts, may read Mr. Rouelle's excellent Memoir on that subject, among those of the Academy of Sciences for 1744.

[2] M. Malouin, however, hath found a way to unite these two metallic substances: but then he does it by the interposition of sulphur; that is, he combines crude Antimony with Mercury. This combination is brought about in the same way that Æthiops Mineral is made; viz. either by fusion, or by trituration only without fire. It resembles the common Æthiops, and M. Malouin calls it Æthiops of Antimony. He observed that Mercury unites with Antimony much more intimately, by melting, than by rubbing them together.

[3] See Mr. Duhamel's Essays on this subject in the Memoirs of the Academy of Sciences.

[4] Mr. Margraaf, an able German Chymist, has made several experiments, which induce him to think that the Acid of Phosphorus is of a particular kind, and different from that of sea-salt. May it not be the Marine Acid, but altered by the union it has contracted with the Phlogiston? Or may it not be, with respect to Phosphorus, what the volatile sulphureous spirit is, with respect to Sulphur? See the Memoirs of the Royal Academy of Sciences of Berlin.

[5] They are much the best, and bear a very fierce heat.
