Preliminary Observations On Recognizing Inorganic Constituents The principal inorganic substances or salts of ino1- ganic bases with organic acids used in medicine which are insoluble in water, are iodin, mercuric iodide, phosphorus, sublimed sulphur, iron valerinate, bkmuth sub- nitrate, subcarbonate, citrate and subgallate, cerium oxalate, calcium fluoride, reduced iron, charcoal, red and yellow mercuric oxide, mercurous iodide, mercurous chloride, precipitated sulphur, zinc carbonate, oxide and phosphide, magnesium oxide and carbonate, and a few organic compounds of bismuth, aluminum, calcium, and iron. The first three mentioned are of course soluble in alcohol. In addition to these a medicinal compound may contain calcium carbonate, sulphate or phosphate, ignited oxides of iron and aluminum, talc, clay, and siliceouscompounds, and possibly other heavy inert salts which take part in the architecture of the sample. Of the above substances, all are soluble in hydrochloric acid except iodin, phosphorus, sulphur, charcoal, calcium fluoride, mercurous iodide, mercurous chloride, ignited oxides of iron and aluminum, talc, and clay. Mercuric iodide does not dissolve in dilute hydrochloric acid but it goes into solutio...
