Aids to Practical Geology. By Grenville A. G. Cole. (Griffin

and Co.)—This is a thoroughly comprehensive manual of what we may call analytical geology, going in more for the microscopical, mineralogical, and chemical structure, as the title indicates, than the more general aspects of geology. The student, indeed, with this book in his hand, has not much need to exercise his own wits, not so much, perhaps, as he ought to have. We cannot help thinking that Mr. Cole uses unnecessarily technical expressions sometimes. Aids to Practical Geology certainly, justifies its title. A Cruise in an Opium Clipper. By Captain Lindsay Anderson.. (Chapman and Hall.)—Captain Lindsay Anderson writes a most realistic account of life in the opium trade, as he saw it from the decks of a well manned and well-armed schooner. The narrative runs as only a sailor can make a narrative run, with the fasci- nating and innumerable details of navigation. The greatest danger the Eamont " ran was from two typhoons, and these are described with considerable force and lively vigour. How the Eamont ' got through these, and how she bumped over the reef to find the long looked-for trading port, are the best portions of the book. The characteristic detail almost enables a seaman, or any one acquainted with sailing, to fancy himself aboard the Eamont.'
