The water which contains these salts in solution was in sufficient quantity to cause the liquor to stand at fifteen degrees of the areometer; that is to say, and according to the indication of M. Gannal, that the liquid should mark from seven to eight degrees during winter, and from twelve to fifteen during summer. The tub was placed in one of the pavilions of the Practical School; and in the same room there were a great number of tables covered with dead bodies for the study of practical anatomy. At the end of two months, the two bodies were withdrawn from the bath, and dissected; no change had taken place in their exterior aspect; the tissues and internal organs were ascertained to be well preserved, and capable of serving for anatomical demonstrations. Other subjects have been examined by the commission of the Academy of Sciences; they had remained in the same liquor since the 2d of December, 1834, and were still sound at the end of April, 1835. We thought it our duty to exact of M. Gannal some other experiments; thus, we desired to see injections with this preservative liquor, of the arterial system; we caused another subject to be injected with ordinary fatty matter; and at a later period we had injected into the vessels of the subject which had received the preservative liquor, a matter composed of suet, and of resin, in equal parts, and coloured with cinabar, (sulphate of mercury.) This last injection was successful. The first injection of saline liquid exacted eight quarts of the liquid, which was introduced through the left ventricle of the heart. The subject examined at the end of two months, was well preserved, did not exhale any fetid odour, and might serve for the common dissection of students. The commission were desirous to know whether a body would rapidly putrefy, if it were withdrawn from the tub and left upon the table of the amphitheatre, exposed to the air, and to the influence of the putrid emanations from the other bodies. A subject was accordingly withdrawn from the preservative saline liquor, and remained fifteen days exposed to the air; no sensible putrefaction took place during this time; this was during the last fifteen days of April. The muscles of the corpse were seen to dry, and, so to speak, to mummify, whilst the tissues which had not come in contact with the saline liquid, or which had not been uncovered and exposed to the air, remained still in a state which permitted an anatomical analysis. We ought to remark, that the tissues which are bathed by the liquid lose their natural colours; but the more deeply disposed organs did not experience the same change; there was no emphysema in the cellular tissue, although we thought we remarked that there was less resistance in the fibres of the organs, than in a subject dead for twenty-four or forty-eight hours.
