    . free from colour and smell, and give no vapours of nitrous — acid when mixed with an equal measure of water. 5 Diluted with 12 parts of water, sulphuretted hydrogen should not throw down a yellow precipitate. 100 eraing@ require for saturation 285 grains of cr. carbonate of soda. ~ Acipvum SutpHuRicumM Purum. E. If the obinine aia . acid contain nitrous acid, heat fZviij of it with between gr, x to xv of sugar at a temperature not quite sufficient to boil the acid, till the dark colour produced shall have disappeared. Other impurities may be removed by dis- | tillation. D. also directs it to be purified by distillation, from a small plain retort, with a few slips of platinum foil, by a gas lamp or small charcoal fire, passing the beak of the retort into a Florence flask. Reject the first tenth, and continue the distillation into a fresh flask until no more than an ounce of liquid remain behind. The dis- tilled product should now be transferred to and preserved in a well-stopped bottle. Sp. gr. 1846. [Professor Repwoop prefers fragments of rock crystal to platinum to prevent explosive bumpings. The operation requires great caution. Arsenic and lead may be removed from the diluted acid by a small quantity of sulphuret of barium. For the method of making anhydrous sulphuric acid, see the Druggists’ Receipt Book. The fuming sulphuric acid of Nordhausen is distilled from dried sulphate of iron. ] Acipum SutpHuricum Dinutum. L.
