    ding fome cauftic vegetable alkali to fome of the fame liquor, until it was faturated. Experiment 10.—The oxalic acid was ad- ded to a part of the faturated liquor of the lafl experiment, but no change was produced. Experiment 11.—To another portion of the fame liquor, the fulphuric acid was added, but no change was obferved. Experiment 12.—To that part of the cal- culus which was not diflblved in experiment 6, I again added cauftic vegetable alkali, and boiled them together; but fome remained in- foluble. It was filtered, and the liquor which paffed through the ftrainer, was faturated as before with the muriatic acid; the fame kind of precipitate was thereby obtained, but no green colour was obferved in the liquor. On adding the nitric acid to this green precipitate, when dry, no red colour was formed, as in the former, but it was dhTolved. Experiment 13.—That part which remain- ed undiffolved in the lafl experiment, was treated again in the fame manner, and attend- ed with the fame phenomena precifely. Experiment 14.—A few grains of the cal- culus were triturated with the cauftic vegeta- ble alkali, which produced a ftrong fmell of volatile alkali.
