Abstract
THE two new sections of Dr. Friend's “Inorganic Chemistry” deal with (i) hydrogen, the alkali metals, the ammonium-compounds, and the coinage-group of metals, and (2) oxygen, jvater, and hydrogen peroxide. The style of the book is now so well established, and so well known, that it is difficult to comment usefully on the individual sections as they appear. The parts now issued appear to be very complete in the information supplied; and the expansion of the section on oxygen to a volume of 350 pages has made it possible to include a much larger number of analytical data than it is now fashionable to quote in a text-book, as well as to deal in unusual fulness with modern work on combustion. By contrast, the volume on the metals of Group I. appears to be somewhat abbreviated, since the three metals of the coinage-group are disposed of in little more than 100 pages. Illustrations are also used less freely, being limited to a few solubility diagrams, etc., and two line-drawings, thirteen in all. The section on oxygen, on the other hand, is illustrated with some fifty diagrams, and-a full-page plate showing the photographs by Burgess and Wheeler of flames near the lower limit of inflammation of methane in air. The homologues of oxygen (sulphur, selenium, and tellurium) are postponed to a later section of Vol. VII., whilst the remaining elements of Group VI. will form a separate Part III.
