Tt was long fi

known, that 2zber and certain other bodies poſſeſſed a peculiar attrattive and a peculiar reputhe-power:“ Theſe powers were ſoon difcovered* to depend on the capacity of thoſe bodies to contain a peculiar aecriform fluid which was named ELECTRICITY y‘ad on the modes of its entering them, reſiding in them, and paſling out of them. That fluid was afterwards found, in certain caſes of its decompoſition, to have light and Heat for its principal elements, This diſcovery ſuggeſted the poſbility that‘it might be the ſame with that fluid by the decompolition of which, in thunder, lightning burſts from the clouds. This TonjeCture was aſcertained to be truth,‘by the late Dr. Fravklin of Philadelphia. The next progreſs of thé lame ſcience was to the diſcovery by the late Dr, Galvani in Italy, of the reſidence of a peculiar fluid. in the living animal body, which might be miadée‘to ſhoot from one bare nerve to ancthér, through the medium of cer- taïn metallic conduétors, and under laws nearly ſimilar to thoſe of eleQri- city. M. Volta not long hnce contrived to elicit this fluid, by means of a pile of layers of metals different in debility‘or in conduêing power, fuch as zinc and ſilver, with intermediate ſtrata of moiſtened paſteboard,—to elicit by théſe' thè galvanic fluid in a quantity in which‘it‘exhibited, identically, the ſame phœnomena,, as eleétricity. The fark, that ís the evolution of light and heat, was produced in the one caſe as well’as in the other. Hence, the neceſſary inference, that eléQricity and’ galvaniſm âre the ſame. The experiments of Volta have been ſince varied’ and extended by the Aſkehan Sociéty in London, by Mr. Davy, by Mr. Hyde Wollaſton, and others, Mr. Tromfdorff lias lately with a pile of‘140 plates of zinc and copper with the humid intermedia, produced ſuch an effüſion of galvaniſm or eleCtricity, 2s inflamed various metallic filings,: He promiſes to make ſoon experiments ſtili more conſiderable, with a pile:of eve 500 or 6006 plates.

Mr. Sennebier has recently aſcertained by a train of eminently curious experiments, that of all poſſible mixtures of the gaſes, that, of three-fourths Azcoot with one-fourth oxygen, the common compolition of the atmoſ- phere, is the mo favourable to vegäâtation. If the Proportion of oxygen be diminiſhed to leſs than one-eighth, the germination cannot take place. Pure unmized oxygen accelerates germination, but at the ſame time enfeebles it. Péaſe grow in diſtilled water without tle preſence of any air, in gaſes of all ſorts, and even in oil, if they have been but previouſly ſteeped in water,
