Abstract
THIS is a new edition of a text-book intended to prepare candidates for one of the science subjects of the London matriculation. It has been much improved since its first appearance, but it still treats the subject in a very superficial way. Although no one could seriously study the subject with this as a guide, it is certainly a useful summary of the main facts, and will probably be found serviceable by intending candidates. The coloured plate of spectra has been corrected, but surely this is superflous in a book which does not even describe an ordinary student's spectroscope. The author has fallen into the very common error of stating that the electric arc gives a continuous spectrum, and he also states that the lines in the spectra of the fixed stars are different from those which characterize sunlight; whereas in a great many cases they are practically identical.
