Rh cause of such irregularity may be sought in some temporary interruption of the vigorous functions of the tree, induced by defoliation, for instance, or by extreme climatic conditions—such as sudden changes of temperature, cold days followed by sudden warm weather, or droughts followed by rain. The absolute breadth of the ring depends on the length of the period of vegetation, and is affected by the depth and richness of the soil, and the influence of light upon the tree.



to the "Medecinische Presse," of Vienna, a Dr. Terc has found a cure for rheumatism in bee-stingiags. Having found that every stinging is followed by a swelling up to a point when the body seems to have become hardened against further effect, he tried the stingings on a rheumatic patient. Upon saturating the patient's system with the bee-poison the rheumatism disappeared—not to return for a long time. Dr. Terc has applied his remedy in one hundred and seventy-five cases and has inflicted thirty-nine thousand stingings; and now keeps a colony of bees on his premises, to be employed in this work.

to a count by Dr. W. J. Beal, of the Michigan Forestry Commission, there grow wild in Michigan seventy species of indigenous trees and three exotics that have escaped from cultivation; and of shrubs, one hundred and fifty native and five escaped exotics.

of Volapük, compiled by Assistant Surgeon M. W. Wood, U.S.A., is announced by Charles E. Sprague, New York. It will contain more than three hundred pages, and will embody the additions and emendations contained in the fourth edition of Schleyer's dictionary. A peculiar feature will be the arrangement of the Volapük-English and English-Volapük parts on the same pages; each page containing a Volapük-English and an alphabetically corresponding English Volapük part.

to the interest that is taken in testing the vision and color-sense of seamen, a writer in the "Lancet" urges the importance of accuracy of hearing in men of this class. During fogs, sounds are the only means vessels possess of giving notice of their presence, and the only means by which they may be warned against dancer of collision. It often requires a nice ear to hear a distant fog-whistle, and a nicer one to determine from what direction it comes. Seamen are as liable to affections which will blunt the acuteness of their hearing as they are to faults of eye-sight.

is another instance of how observation trips up a priori reasoning. A correspondent of "The Spectator" relates that some one wrote to an English paper to say that "blackbirds did not eat fruit because they liked it, but because they were thirsty, and recommended we should place pans of water on the gravel walks and so save our garden fruit. A cottager in Montgomeryshire, being told of this interesting fact, replied in the dialect of that part of the country: 'Dern the bruts! they cross the bruck to come to my geërding.'"

opinion is growing that bovine tuberculosis is frequently transmitted to the human subject by eating the flesh and drinking the milk of tuberculous cows. It is to be hoped that thorough boiling of the meat destroys the vitality of the bacilli, which are assumed to produce this disease, but we are not warranted in believing that roasting the meat, as usually practiced, will have that effect; and as milk is seldom boiled before being partaken of, it is clear that the milk of a tuberculous animal is unfit for food, and dangerous to life.

North Borneo is fast approaching the state of a regularly organized colony, with a fine promise of prosperity. The territory has been divided into nine provinces, named after the founders of the company, and grants of land have been issued covering 475,289 acres, in five of the provinces, those on the coast having the preference. The grantees are mostly Dutch; and a large proportion of the land granted is intended for tobacco cultivation. The total area of the territory will probably be found to be more than 20,000,000 acres. The price of the land, originally one dollar an acre, has been raised to two dollars. Regular steam communication was instituted September 1, 1888, between Sandukan and Hong-Kong and Singapore.

is told in the Ohio papers of a railroad engine-driver who was suspended because the examining physician pronounced him deaf. He asked to be reinstated because, when on a moving engine, he could hear perfectly well. This was found, on experiment, to be the case. Prof. W. M. Williams matches this story with another, within his own observation, of a man who was painfully deaf in a quiet house, but "could hear ordinary conversation with perfect ease in a cab or railway-carriage, provided the jolting was considerable."

of Universal Climatology" is announced as in preparation by the Observatory of Rio Janeiro, M. L. Cruls, director. It is intended to present methodically the climatological data of as great a number of places on the earth as is possible, reduced to uniform standards of notation and terminology.
