A SET of tables for the identification of minerals is very useful to mineralogists and others; and as this note-book contains such tables and little else, it is welcome. The information is conveniently arranged so that it can be quickly referred to, nevertheless there are so many omissions that the book cannot be used to the exclusion of other books on mineralogy, and consequently its chief claim to consideration, that of saving time, falls to the ground. For example, under the heading of lead ores, only galena and cerussite are mentioned, although six compounds of bismuth and five of antimony are described. It may be hoped that Mr. Barringer will see his way to making his book more complete in future editions.
