Handbook, of Physical Geology. By A. J. Jukes Brown, B.A.,

F.G.S. (George Bell and Sons.)—Mr. Jukes Brown has given a careful account of the historical geology of the districts which are parti- cularly adapted for research, and from which most of our present knowledge is derived, and has produced a handbook of the moat complete kind, full of interesting and useful information, while it is interspersed with numerous woodcuts of fossils. The attempts to unravel and separate different phases of ancient geography are of special value. We can commend the volume as a very useful guide indeed, particularly ao to the student wishing to geologies in a afloat country ; he will find that all the beds of any value or interest are carefully described. The remarks on the probable history of many beds will assist him in comparing rival theories, or, if need be, testing his own. We cannot imagine a more enjoyable holiday than an expedition to places possessing, as they often do, such charms of natural scenery, together with geological strata of such scientific value. The present volume, besides rendering many abstruse clues. tions easier, will materially add to the knowledge and happiness of the explorer.
