"Synopsis" is published as Bulletin No. 16 of the United States National Museum. In it the authors have endeavored to give concise descriptions of all the species of fishes known to inhabit the waters of North America, north of the boundary between the United States and Mexico. The classification adopted is essentially based on the views of Professors Gill and Cope. The rules of nomenclature generally recognized by naturalists, and recently formulated by Mr. W. H. Ball, have been followed, almost without deviation. Under the head of each species enough synonomy has been given to connect this work with other descriptive works, and no more; and the principal references are to the original descriptions of such species, to Dr. Günther's "British Museum Catalogue," and to other works in which special information is given, or some variant specific name is employed.

magazine, the general scope of which is indicated by the title. The present number contains a variety of literary, popular scientific, and hygienic articles by popular authors, a "Health and Habit" department by Dio Lewis, and departments of a "domestic" character. The magazine is well printed, on good paper, and looks well.

Professor Newcomb visited the principal observatories in Europe in 1883, for the purpose of taking note of the improvements in astronomical instruments which had been adopted in them, and this report embodies the results of his observations. Among the objects he describes are the great Vienna telescope and its mountings; the great domes at Paris and Vienna; the great Russian telescope at Pultowa, with the apparatus for mounting it, now making at Hamburg; reflecting telescopes in France, the equatorial coudé (a contrivance by the aid of which the eye-piece may always point to the north), the Strasburg meridian circle, etc. The observations are supplemented by the author's own practical conclusions.

journal is designed to be a monthly review of meteorology and allied branches of study. It takes up the subject earnestly and in a manner showing that the editor has a proper comprehension of what such a publication should be.
