er quantities of water to the volcanic furnace beneath. Hence the remote causes of the outburst of 1883.
Physics. By Professor George F. Barker. Pp. 60.—Besides the results in general physics, Professor Barker mentions the studies that have been made in the physics of liquids and gases, light, acoustics, and electricity, and special applications.
Mineralogy. By Professor E. S. Dana. Pp. 26.—The subject is considered under the headings of "General Works on Mineralogy," "Crystallography and Physical Mineralogy," "Chemical Mineralogy," "New Mineral Localities in the United States and elsewhere," and "New Minerals."
Anthropology. By Professor Otis T. Mason. Pp. 56.—This account includes considerable technical matter; but we find in it sections on the ethnology of the American aborigines, and on the glossology, comparative technology, sociology, and mythology and folk-lore of our tribes.
Astronomy. By William C. Winlock.—Mr. Winlock works as a substitute for Professor E. S. Holden, whose manuscript review, already prepared, was lost in removing his library. Faye's "Cosmological Theory," and G. H. Darwin's review of it, new discoveries of nebulæ, investigations of astronomical constants, recent star catalogues, studies in parallax, in variable, new, or temporary stars, in stellar spectra, proper motions, and photometry, astronomical photography, what has been done and said about comets, the studies of Langley and others on the sun, and of other astronomers on various planets, receive attention.
Zoolögy. By Professor Theodore Gill. Pp. 53.—The continued tendency toward the special study of embryology, and of animals from an embryological point of view, is remarked upon: At the same time systematic zoölogy has at least maintained its course. Particular mention is made of Dr. Boulenger's catalogue of the lacertilian reptiles in the British Museum, Professor Cope's "Tertiary Vertebrata," and Professor Marsh's "Dinocerata." The subject is reviewed according to the various groups of the animal kingdom in which memoirs have appeared.
North American Invertebrate Paleontology. By John Belknap Marcou. Pp. 47.—Mr. Marcou gives summaries of the various monographs that were published during the year, the whole furnishing a fair and tolerably full representation of what was accomplished. All of these reviews, except the "Geography" and the "Paleontology," which is itself a bibliography, add bibliographies of their subjects, and necrological notices. In Professor Gill's zoölogy the bibliographical notices are given in the text according to the groups to which the subjects belong.
