![minute (spirit-lamp) flame ; the facets of the crystals thus formed (on the cooler situations) will be seen in some places with the unassisted eye, but more distinctly by means of a 4-power lens. In solution:—ammoniacal nitrate of silver produces a lemon- coloured (arsenite of silver) precipitate. Ammoniacal nitrate of copper throws down a fresh grass-green [arsenite of copper) pre- cipitate. Transmission of sulphuretted hydrogen produces a bright yellow (sesquisulphuret of arsenic) precipitate. Lime- water precipitates a white [arsenite of lime) powder; but this test is not one of reliance. Placed with zinc, and diluted sulphuric acid, in Marsh's appa- ratus, the arseniuretted hydrogen thence arising, when lighted, will deposit metallic arsenic on a piece of glass held over the flame. The precipitates referred to, if washed and dried, may be treated as directed above for arsenic in the dry or solid condition. £Note.—In testing suspected matters obtained from the stomach, these (and, in cases of death, the stomach itself) must be cut or broken down, and boiled during at least f hour: if not sufficiently fluid, add distilled water. Strain, and with addi- tion of a small quantity of potash, again boil during | hour, and filter. If this liquor manifests either alkaline or acid re- action, neutralize with potash, or with acetic acid, as may be required; then acidulate it faintly with hydrochloric acid. Solution of nitrate of silver will remove the acid ; and solu- tion of muriate of soda will precipitate any excess of silver. The liquor may now be experimented on with the above tests.] Nitric Acid. (Obj.)—To render the acid inert by neutralizing it with earthy carbonates ; and then to withdraw it. (Treat.)—Mixtures composed of chalk, or magnesia, with sweet milk, or water ; linseed decoction, or other mucilaginous drinks ; soap dissolved in water; and enemata of the same in- gredients. Tests. By addition of copper or lead-filings, and application of heat, rich red fumes are evolved. Hydrochloric (or Muriatic) Acid. (Obj.)—Same as in preceding. (Treat.)—Chalk must be avoided, as chloride of calcium will be formed; but the other means directed for foregoing acid are proper.](https://iiif.wellcomecollection.org/image/b21013950_0294.jp2/full/800%2C/0/default.jpg)
