I found Sherlock Holmes alone, however, half asleep, with his long, thin form curled up in the recesses of his armchair. A formidable array of bottles and test-tubes, with the pungent cleanly smell of hydrochloric acid, told me that he had spent his day in the chemical work which was so dear to him. "Well, have you solved it?" I asked as I entered. "Yes. It was the bisulphate of baryta."
But long hours at the laboratory had made it very hard for FitzMorris to concentrate his brain on anything for a long time; he was happily dreaming, let us hope, of carbon bisulphate, when the roar, "How's that?" woke him up. He had to give the man "not out"; there was nothing else to do. Twenty minutes later, with a scandalous scythe-stroke, Bridges made the winning hit.

The British Army is the only army which has succeeded in doing this. All excreta which cannot be burned is buried so that it cannot be reached by flies. As it may happen through accident or carelessness that water supplies have been contaminated, it is the rule to sterilize all water used for drinking purposes, either by boiling, by the use of bisulphate of soda, or by chlorine.
A large number of these coal-tar colours show a tendency of going so rapidly and greedily on to the fibre that it is necessary to find means to restrain them. It is usually also best to dye in a bath slightly acid with sulphuric acid, or to add some bisulphate of soda.
But we must observe that with these dibasic acids it is possible, by adding insufficient alkali to completely saturate them, to obtain salts in which only one hydrogen atom of the acid is replaced by the metal of the base. Thus sulphuric and carbonic acids yield NaHSO , acid sulphate or bisulphate of soda, and NaHCO , bicarbonate of soda, respectively.
Boil the finely divided substance with about one-eighth its bulk of pure hydrochloric acid; add from time to time potassic chlorate until the solids are reduced to a straw-yellow fluid. Treat this with excess of bisulphate of sodium, then saturate with sulphuretted hydrogen until metals are thrown down as sulphides. These may be collected and tested.
