![at first cooling, but soon becomes acrid and irritating. It slightly reddens the tincture of turnsol, has a very powerful, and, it may be, deleterious, odour, which is only supportable when mixed with a very large quantity of air. If is then found to be the same as the odour of bitter almonds. CHEMICAL PROPERTIES. Prussic acid is very volatile ; in fact, it boils at 26°.5 (79.7 Fah.) under a pressure ofOm.76b, and at 10° (50 Fah.) it sustains a column of mercury of 0m.38 ; still its congelation takes place at 15° (59 Fah.). Also, when a few drops are put on paper, the portion which b 0m.76 probably means ]^of a metre ; if so, it is equal to 29.9 English inches, and Qm.38 “ 14.95. With regard to the 0m.38 as the measure of a column of mercury, it may be useful to remark, that it is not uncommon to esti¬ mate the force of the expansion of all fluids at any tem¬ perature by the column of mercury which they will sus¬ tain. This is done by introducing into a Torricellian vacuum a small portion of the fluid to be examined, and applying heat thereto. The apparatus is a curved tube, with two pretty nearly equal legs, one of them being sealed, and the other open to the atmosphere. The force of the vapour is shewn by the depression of the mercury in the sealed leg, and its elevation in the other; the differ¬ ence in the height of the two columns being the measure of it.—Tr.](https://iiif.wellcomecollection.org/image/b30796568_0123.jp2/full/800%2C/0/default.jpg)
