This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1805 edition. Excerpt: ...of muriatic acid it will therefore be expedient to employ an apparatus in which the water shall neither come into contact with the fingers nor with corks. For transmitting the metallic wires, perforated glass stoppers, one of which has an aperture large eno'ugh to allow the water to escape as the gases are generated, would answer the purpose sufficiently. It is desirable also that the water employed should be well freed from air, and that the atmosphere should be excluded; for, if muriatic acid be generated, it will otherwise remain to be proved that azote is not one of its components; and this presumption is even confirmed by the extreme minuteness of the portion of muriatic acid which seemed to be produced in my experiment. If water contain all the elements of that acid, and nothing more be required to effect its transmutation than a change of their proportion, we might expect a considerable and unequivocal production of muriatic acid by the process of Galvanism. Another circumstance suggesting the presence of azote in this acid is, that on examming the liquor obtained by detonating impure hydrogen and oxvgen gases jn close copper vessels, Mr. Keir found that a small quantity of muriatic acid accompanied the nitrous acid thus formed.--See Keir's Dictionary, p. 119-" The precautions which I have suggested will not be thought trivial by any one who recollects that one of the most accurate and celebrated chemists of this or any other time was misled to a belief that he had effected the synthesis of muriatic acid, by a circumstance which was neglected solely from its apparent insignificance. The source of fallacy, in the instance alluded to, shows how unaccountably that acid may find its way into the subjects of our experiments, and mtroduce...
