Not illustrated. 1817 Excerpt: ...specific gravity O'S?. It is much more volatile than alcohol, or even sulphuric ether, assuming the gaseous state when riot hotter than 640. None of the usual tests indicate the presence of any muriatic acid. It does not affect vegetable blues, nor give out acid when agitated with an alkaline ley, or occasion an immediate precipitate when mixed with nitrate of silver. But when brought in contact with a combustible it burns readily with a green-coloured flame, a very considerable portion of muriatic acid is immediately disengaged in the state of vapour. This very extraordinary fact was first observed by Gehlen: it has been minutely examined by Thenard. When allowed to remain for a long time in contact with an alkali, it does give out a portion of muriate acid, and it slowly produces a precipitate in nitrate of silver after the interval of several days, and the quantity of precipitate increases with the time. But in neither case is the ether decomposed, or deprived of the property of giving out muriatic-acid when burnt. Thenard has endeavoured to ascertain the composition Comjxuiof muriatic ether. From the quantity of muriatic acid110"' which disappears during its formation, he has calculated that 100 parts of muriatic ether contain 29'M of acid; an enormous quantity, since it exceeds the proportion of real acid in the strongest muriatic acid of commerce. By mixing determinate portions of muriatic ether gas with oxygen gas, firing the mixture, and ascertaining the products, which arc only carbonic acid and water, he endeavoured to ascertain the proportion of the other constituents. The followis the result of his examination: Basse obtained it of the specific gravity 0820, and Gehlen of 0845. Here we must consider weight as a mark of jmrity. Hence it is o...
