    the experiment upon which his fufpicion was grounded, is far from being fatisfaclory. At any rate, the proportion amounting to not a hun- dredth part of the whole mafs, is too inconfidera- ble to require being noticed. Mr. Scheelc has informed us that the powdered calculus was difiblved by concentrated vitriolic acid, with the affiftance of heat, but that the muriatic acid had not the fmallefc effect upon it, even when boiled with it. Thefe fimple experi- ments were fufficient to prove that it is not chiefly formed of calcareous earth. It is a pro- perty of that earth to combine with vitriolic acid into an almoft infoluble concrete, while it unites very readily with muriatic acid, into a compound fo eafy of folution as to attract water from the atmofphere. The calculus was attacked by concentrated nitrous acid with great violence, and with the affiftance of heat it was readily diffolved by the fame acid diluted. The acid of fugar, which attracts calcareous earth from every other acid, and unites with it into a fubftance infoluble in water, did not produce any precipitation when mixed with this folution : neither was there any material effect from the addition of alkali. The compound of the matter of calculi with the fliluted nitrous acid, was of a yellow colour. When
