with all requisite detail, and there is no doubt that the work will be prized by naturalists as a substantial contribution to zoölogical science. But, at the same time, the interests of a larger circle, viz., the educated though unscientific public, have not been overlooked. Indeed, what may be called the "popular" aspects of the subject in hand, namely, the life-histories of the species, and their economic and other practical relations, are considered at length.
Narrative of the Expedition of the Polaris. Edited by Rear-Admiral C. H. Davis. Pp. 696. Washington: Government Printing-Office.
The story of the gallant Captain Charles Francis Hall is here told in simple, unaffected style; indeed, as it would appear, for the most part in the very words of Hall himself, and of his companions in danger and misfortune. The volume is of quarto size, on heavy calendered paper, elegantly printed, and adorned with a steel-plate portrait of Captain Hall, a vignette of the Polaris, some forty full-page wood engravings, numerous smaller engravings, and six maps. It is, indeed, a fitting monument to the genius and intrepidity of Captain Hall and the modest heroism of his officers and crew.

The United States Pharmacopœia, as is well known, has been issued in revised editions every ten years, since its first appearance in 1830. These revisions have been made under the authority and direction of "The National Convention for revising the Pharmacopœia," consisting of delegates from medical and pharmaceutical colleges; the real work, however, has
