288 co-operate with Englishmen in a work in which all men of science were interested. The cataloguing of general scientific work, as it at present stands, is not at all satisfactory, and the adoption of a general system, by the scientists of all countries, which seems likely to follow the conference, will undoubtedly be a long step in advance.

excessive cost of the rare earths used in the composition of the Welsbach and other incandescent gas mantles has led to the formulation of a process by which the residues of the old mantles can be reduced, separated, and used again repeatedly in new mantles. The process consists in reducing the mantles with ten times their weight of bisulphate of sodium, taking up the product in water, and adding excess of oxalate of ammonia to re-dissolve oxalates of thorium and zirconium, while the oxalates of cerium, lanthanium, erbium, and yttrium remain insoluble. The liquor is then filtered, the undissolved oxalates remaining on the filter. The residue is then treated with concentrated hydrochloric acid to obtain the oxalates of thorium and zirconium.

supposition that by comparing numerous elements in different myths, and thus discovering that many are identical, a common origin is proved, was treated as a fallacy by Dr. Brinton in a paper read before the American Association. The method in question. Dr. Brinton held, does not take into account the essential unity of the human mind, wherever it may be, and the laws that govern its activity. Because of the tendency of the mind, everywhere and in all conditions, to act in the same manner, we find myths of similar character in all parts of the world. They may therefore be very similar, and yet very diverse in origin.

of fifteen terminal moraines was described by Mr. F. B. Taylor, in a paper read in the American Association, as lying between Cincinnati and the Straits of Mackinaw.

cultivation of flowers for export and for the perfumery factories at Grasse is an important industry on the Riviera. It is officially estimated that the value of flowers annually exported from Nice, Cannes, Beaulien, and Mentone is six hundred thousand dollars.

, of Harvard University, one of the most eminent of American geologists, died at Lake Sunapee, N. H., August 19th, in his seventy-seventh year. He was born in Northampton, Mass.; was graduated at Yale in 1839, and, after spending about twenty years in various geological surveys, was appointed Professor of Geology at Harvard in 1864. His geological work began in service as assistant geologist in New Hampshire, subsequent to his graduation, after which he traveled and studied in Europe. In 1847 he engaged, in connection with John W. Foster, in the Government survey of the Lake Superior region, the published result of which, Foster and Whitney's Report, was a famous book in its day and long the chief authority. He next spent two years in the examination of the mining and mineral resources of the States east of the Mississippi, and published The Metallic Wealth of the United States in 1854. He next became State Chemist and professor in the State University of Iowa; made a geological survey of that State; surveyed the lead region of the upper Missouri, in connection with the official surveys of Wisconsin and Illinois; and from 1860 till 1874 conducted the topographical, geological, and natural-history survey of California, publishing the results in more than six volumes. He translated the Use of the Blowpipe of Berzelius, published a Yosemite Guidebook, and contributed much to scientific and other periodicals. Mount Whitney was named after him. He was a brother to William Dwight Whitney, the philologist.

the results of the measurements of the velocity of rotation of the planets by the spectroscopic method reported by Prof. J. E. Keeler to the British Association is the observation that the inside of Saturn's ring moves more quickly than the outside, and consequently that the constituents of the ring do not obey Kepler's third law. These constituents are therefore not solid particles, a fact which has been previously established by other methods.

, assistant in charge of the office of the Smithsonian Institution, died at Bay Head, N. J., September 20th, in his thirty-seventh year. He was a son of Prof. Joseph Winlock, first Director of the Harvard Observatory and Superintendent of the American Ephemeris and Nautical Almanac, and inherited a fondness for astronomy from him. He was appointed curator of international exchanges and afterward assistant in charge of the office of the Smithsonian Institution; prepared the Annual Reports on the Progress of Astronomy from 1885 to 1892; contributed articles on astronomy to various periodicals; and represented the Secretary of the Smithsonian Institution at various scientific meetings, including the centennial anniversary of the American Philosophical Society.

, ex-Professor of Biology in Johns Hopkins University, died in Burley, England, October 29th, in the forty-ninth year of his age. He was born in Newry, Ireland; was a fellow of Christ College, Cambridge, where he received the degree of A. B. in 1879, and that of A. M. in 1877; and was appointed to the professorship in Johns Hopkins on the recommendation of Prof. Huxley. He retired from that position in 1893 on account of ill health.
