Uniform time for the whole of France-that of Paris-has been de- cided upon by the French govern ment, to commence with the opening of the Universal exposition, in 1889.
 Dr. Jastrow, of the University of Wisconsin, proves that the ear is the dominant organ of the mind in some persons, and the eye in others. Peo- pie are therefore ear-minded or eye minded. Dogs are usually nose- minded.
 Vegetarianism does not protect from cancer. In hospital at Jeypore, India, during the last eight years, forty -one operations for cancer have been performed on the persons of meat. caters, and sixty-one on strict and life long vegetarians.
 Prof. Emmerig, of Germany, finds bees the most reliable of all weather prognostications. They become rest less and irritable before a storm, and in eight or nine instances within three years their indications have proven correct when the barometer has failed.
 According to a Chicago wagon maker, white oak requires eighty years to mature; shell-bark hickory, from thirty to fifty years white ash, thirty years; tulip-tree, sixty or more years: and rcd or Norway pine, at least sixty years. Artificially grown, fifty five thousand feet of these kinds of lumber may be obtained from each acre, the present Chicago price being $14.50 per thousand.
 THE YOUNGEST MooNs.-The fact that the satellites of Mars were not discovered until 1877 is considered very remarkable by Mons. E. Dubois. He suggests that they may have not long held their present places, but that they may be bodies drawn-only recently-from the zone of little plan cts lying between Mars and Jupiter. He believes that several others of these asteroids are likely to become moons of Mars.
 OIL- SPREADING ROCKETs.-A Ger man patent covers 8 rocket carrying a cylinder of oil, together with an ex- plosive charge which scatters the liq- uid when the projectile reaches the journeys end. In experiments at sea the rockets have been thrown nine hundred feet against strong gale By this means oil can be distributed in different directions, securing to the storm tossed vessel large area ot smooth water.
 THE CoRoNAL LIGHT.-The light lemitted by the corona during the so- lar eclipse of 1886, was less than half as great as in that of 1878, according to Captain W. de W. Abney and MT, T. F. Thorpe. The total light of the corona in 1878 was 0O72 of that of a standard candle at one foot distance or 3.8 times that of the full moon, or 0.0000069 of that of the sun. Proba- ply the brightest part of the corona was about fifteen times brighter than the surface of the full moon, or 37, ,OOC times fainter than the surface of the sun.
 WORK OF THE SUNBEAMs It has been estimated that an average of five feet of water falls annually over the whole earth. Supposing that con. densation takes place at an average height of 5000 feet, remarks General Strachey, the force of evaporation tc supply such rainfall must equal the Hitting of 322, 2,000,00 pounds of water 5000 feet in every minute, or about 800, O,O00,000 horsepower constantly exerted. Of this great energy very small part is transferred to the waters that run back through rivers to tho sea, and still smaller fraction is util. ized by man; the remainder is dissi- pated in space.
 CHOLERA INOCULATION.-Five year. ago Pasteur endeavored to discover $ means of curing cholera by inocula. tion, but allowed the matter to droI on the death from the disease of an as- sistant investigator. The subject hal been followed up, however, by Dr Gamaleia, of Odessa, who has found 6 method by which the cholera has been cured in animals by the inoculation oi the cholera virus, and which 1t is con- fidently believed may be applied te man. His experiments are to be re- peated before committee of the French Academy of Sciences, which holds prize of 100000 francs to bt awarded for cure for cholera.
 A FLAMELEss Among the most promising of new explosives seems to be 'securite," lately discov. cred by Herr Schoeneweg, and already manufactured on 6 considerable scale in Germany. Securite is granulated powder of light yellow color, and ar odor resembling that of bitter al- monds. It is quickly manufactured does not deteriorate, is of about the same cost as dynamite, and of nearly equal explosive power. It cannot bt fired by friction, blow or jar, only
