Abstract
IN the Notes on “Recent Science,” in this month's Nineteenth Century, the writer, in an account of the results of the researches of M. Pictet and M. Cailletet on the condensation of the so-called permanent gases, draws attention to the lone-neglected paper of Mr. Perkins “On the Compressibility of Water, Air, and other Fluids,” an abstract of which, and apparently the only one with which the writer is acquainted, appeared in Thomson's Annals of Philosophy, N. S., vol. vi., 1823. The paper was intended for the Royal Society, but, being mislaid, was not read at the appointed time. Either it or a second paper was, however, brought before the society on June 15, 1826, and appears in the Philosophical Transactions for that year. In this paper, as in the brief record in the Annals, Mr. Perkins announces that he had effected the liquefaction of atmospheric air, and other gases, by a pressure of upwards of 1,000 atmospheres, and fully describes the apparatus which he had employed, which is, in principle, very similar to that of M. Cailletet. He thus describes his results in the case of aëriform fluids:—
