Excerpt from The Use of the Blowpipe in Chemical Analysis, and in the Examination of Minerals Closely connected with his canon, thus we find him expressing the cornposition of magnetic iron ore (traité, p. 145) as that of one atom of oxi-s dule (protoxide) of iron, with M atoms of oxide (peroxide), the former containing two atoms of oxygen, the latter three, and, adopting Latin names and terminations, he calls the protoxide of Iron, omi dam ferrosum, the peroxide oridum ferricmn, and the compound we are speaking of, oxidant ferroso ferricum. This, and similar terms, I have taken the liberty toreject, using instead those commonly adopt ed in this country. The chemical and mineralogical symbols are composed of the initial letter or letters of the Latin names of the various elementary boa dies, for'the former, the common Roman capitals are used, over which are placed as many data as 'there are supposed to be atoms or Oxygen com bined with the electro-positive element, for the mineralogical symbols Italic capitals areem~ ployed, and the dots omitted. In 'the formulae they are connected by the usual algebraic sign of addition. These formulae I have omitted in toto, but that the reader may not lose the information they are intended to convey, -l have subjoined, in notes.
