and will be more apt to take fire than the Powder of Antimony. Therefore considering that Sulphur boil'd in a Lixivium, may be precipitated by Rhenish or white Wine; and likewise that by Acids I could precipitate other sulphureous Con∣cretes out of lixiviate Solvents, such as crude Antimony; And tho' common Sulphur yields a white Precipitate call'd Lac Sulphuris; yet I concluded that Antimony would yield a yellow one, as well by being made by Oyl of Vitriol, as Length of time. Wherefore I put a fresh Solution of Antimony into one Glass, and some of the Orange colour'd Mixture into another, where by dropping Oyl of Vitriol into the lat∣ter, it would become transparent, whereas the same Oyl would turn the other clear Solution in∣to a deep Yellow. But in this Experiment we are to observe, that the Solution of Antimony must be fresh, otherwise in Winter it will scarce succeed.
