A Manual of Organic Chemistry. By Hugh Clements. (Blackie and

Son.)—This is another chemical manual, newly added to the legion called into existence by the examinations of the Science and Art Department. It is not, in any sense, a satisfactory book; we should have to speak very harshly of it, wore we to mote out full justice to it. Some amusement, however, may be got from this little volume. Lot the beginner in chemistry try to answer the following five questions sot by Mr. Clements (see pp. 172 to 176) :—" What organic substances leave a black residua on being heated ?" " What organic substances produce an agreeable odour when heated P" " What organic substances dissolve in alcohol P" " What organic substances taste peculiar ?" "Make a quantitative analysis of the following mixtures,—pork, apples, opium, coal-tar, ink." Those ques- tions of Mr. Clements's are ludicrous enough, but what would his answers be ?

We have received from the Religions Tract Society a collection of Scripture stories, Christmas and New Year's Cards, reward tablets, be., which are all well adapted for Sunday and day-school class prizes. The designs are pretty, the illumination in good-taste, and the texts well selected and appropriate.
