576 lower type was caused by the plantation of one organism of the ganglionic type upon another, the implanted organism giving rise to the cerebro-spinal nerve system and internal skeleton." The author further believes that the ganglionic type is itself a compound, the ganglions being parasitic on a simple cellular matrix.

passed by the American Association at its Detroit meeting suggested, as a remedy for the obstacles imposed on the interchange of scientific thought by the prevailing diversity of tongues, the adoption by the civilized nations of an alternate language of Learning, Law, and Commerce, to be taught in higher schools in combination with the mother tongue, and used in interlingual correspondence and printed records. The resolution farther authorized the officers of the association to pledge its co-operation in a general movement seeking that end, and to provide for its representation in any conference on the subject that may be called.

Guildford Natural History Society, England, is trying to have Walmer Forest set apart as a sanctuary for wild birds, in which they and their nests and eggs may remain unmolested throughout the year; that it may not be let at any time for game preserving or for any purpose hostile to birds; and that it remain in perpetuity a national memorial of Gilbert White.

with portrait, of the late James Joseph Sylvester, Savilian professor of geometry in the University of Oxford, and formerly professor of mathematics in Johns Hopkins University, appears in the Proceedings of the Royal Society of London for May 9th. In the writer's opinion, Sylvester was one of the greatest mathematicians of all time, .though it may be doubted whether he will take a place among those who "occupy absolutely the front rank" His greatest achievement was probably his paper entitled Algebraical Researches, printed in the Philosophical Transactions for 1864; but his published works do not properly represent his genius and greatness. He was so oppressed with floods of ideas that he was unable suitably to organize his researches. His personal character was one of singular beauty, and its salient points were simplicity and honesty.

mask found inside the wrappings of a mummy pack in a grave at Chimbote, Peru, and in a valley thickly dotted with ancient cemeteries, is believed by Mr. George A. Dorsey to be unique. It was hammered from a single nugget of copper, and shaped by the aid of a mold or block. All the features are well formed and distinctive except the nose, which is pinched and dwarfed. A hole was made for the mouth, the ragged edges showing the method of the operation being still visible within.

unusual competition is described by the Lancet as recently occurring in Milan. It seems that the nose possesses a peculiar significance for the Italians—so much, in fact, that they have a "cult of the nose," which has during the last seven years held two "concorsi di nasi" (nose competitions). The former of these was at Padua in 1891. The more recent one took place at Milan, when there were thirty-six competitors, the first prize being a gold medal.
