The Parts of the Medical WATERS of SCARBROUGH. Prepared and given by Dr. Witty: together with an account of them. But this I find not. The Preparations are these, The Phlegm, and Acid Spirit, not strong. The Sedement upon evaporation, of an ash-colour, a bitterish and nitrous Tast. The Precipitate, upon the mixture of Gall-powder; black, and of little Tast. One or two Grains will precipitate ʒj out of a Gallon of the Water. The Nitrous or Essential Salt, as I take it, before the Precipitation be made. The like Salt, after the Precipitation is made. These Salts have also somewhat of a Nitrous Tast, but mixed with a smatch of a Vitriolick: And the latter, I take notice, is figur'd into long square Crystals, or little square Bars. The Black Precipitate calcin'd. The Lixivial Salts, made, as I take them, from the Precipitate, and from the simple Sediment or Extract both before and after Precipitation made: somewhat like to that of Vitriol.
