This order of salts, entirely unknown to the ancient chemists, was discovered in 1786 by Mr Berthollet--A

SECT XIX--_Observations upon Muriatic and Oxygenated Muriatic Acids, and their Combinations_

Muriatic acid is very abundant in the dom naturally combined with different salifiable bases, especially with soda, linesia In sea-water, and the water of several lakes, it is combined with these three bases, and in mines of rock-salt it is chiefly united to soda This acid does not appear to have been hitherto decomposed in any chemical experiment; so that we have no idea whatever of the nature of its radical, and only conclude, froen as its acidifying principle Mr Berthollet suspects the radical to be of a metallic nature; but, as Nature appears to for miasmata with aeriforas to exist in the atmosphere, which is certainly not impossible, but cannot be admitted without proof

The muriatic acid has only a moderate adherence to the salifiable bases, and can readily be driven from its combination with these by sulphuric acid Other acids, as the nitric, for instance,volatile, woulddistillation, with the muriatic About one part of sulphuric acid is sufficient to decompose two parts of decrepitated sea-salt This operation is perfor Woulfe's apparatus, (Pl IV Fig 1), adapted to it When all the junctures are properly lured, the sea-salt is put into the retort through the tube, the sulphuric acid is poured on, and the opening iround crystal stopper As the aseous form in the ordinary temperature, we could not condense it without the presence of water Hence the use of the water hich the bottles in Woulfe's apparatus are half filled; the as, driven off from the sea-salt in the retort, combines with the water, and for spirit of salt_, or _Glauber's spirit of sea-salt_, whichname _muriatic acid_

The acid obtained by the above process is still capable of co distilled fro acid, which we naenated asseous form, and is absorbed, in a nation of water with this gas is pushed beyond a certain point, the superabundant acid precipitates to the bottom of the vessels in a concrete form Mr Berthollet has shown that this acid is capable of coreat number of the salifiable bases; the neutral salts which result fro with charcoal, and rations are very violent and dangerous, owing to the great quantity of caloric which the oxygen carries alongst with it into the coenated muriatic acid
