| Show scientific ANY the list of double and multiple stars now exceeding 1000 is increasing with such a rapidity as to suggest that single stars like our sun which has no large satellite or companion are exceptions to the rule the double stars are of two kinds the telescopic tele binaries are systems whose two components axe are both seen revolving around a common center while ii IQ the spectroscopic binary the the existence of the second sun aun is known only by the evidence 0 of the spectroscope having never been seen by man the well oz of the former range from many centuries downto twenty five years while spectroscopic tro binaries may have periods of only a few weeks among the new discoveries co axe are those of a telescopic binary whose revolution is completed in live five and a half years and a spectroscopic binary which has the astonishingly short period of three days and itself revolves about the large star castor in 1000 years sirius estimated to toe be four times as bright as any other star in the northern heavens Is a remarkable telescope binary with a period of a little less than fifty two years its companion long expected to exist was first seen in 1862 by alvin G clark claris and a few months ago it was picked up by the lick telescope after having been out of range for six and a halt years yeats A bare iron wire and an insulated coper wire wound helically on an iron iran core constitute the novel primary battery of mr N B stubblefield of murray ky and the electrolyte may be simply water or moisture it is claimed the form increases the output of current while yielding inductive effect that may be utilized in a secondary coil the cell may serve as aa a self generating electromagnet and to is said to be adapted for telephone telegraph and electric bell purposes and especially valuable in electro therapeutics the question of placing electrical conductors in or near powder maga has been submitted to a committee of the french academy of 0 sciences t who make these recommendations all underground electrical con ductor sas well as gas and water pipes must be kept at least 80 feet from the magazines aerial lines should not be allowed within 60 feet and must be arranged so that no broken wire can fall upon the magazine if af light Is required inside the magazine alt all wires are to be in strong metallic pipes and all switches fuses etc are to be qu on the outside of the building only fixed lamps lamm protected by a seconder efi delope of glass may be used and no current should have a voltage higher than electric bells belle only those these using a very small current to be 1 allowed I should be at least 12 feet from the powder As all wires are liable to be struck by lightning no die tion is made between te

fuhl two kinds of bacteria neither occurring in the rhine rhin were placed in a shallow pit neatly nearly full of water and in one hour one species had passed through 24 feet of gravel to a second pit the other species appearing in the second pit within two hours an epidemic in an ant colony has been noticed by a bombay bacteriologist who suspects the disease may ble be the bubonic plague and is experimenting to settle the question not the least interesting of the phenomena now being studied by as Itron omers is the little observed or a faint light 20 or 25 degrees in diameter that is seen by the naked eye only o in ac and always exactly opposite or degrees from the sun it bears some resemblance to the brighter and more familiar zodiacal light dr E E barnard has noticed in fact that late in the season the two appearances appe aTances become joined by a band of light 3 or 4 degrees wide although this is not visible when the first appears in autumn the cause of thea the weird glow in the blackness of night is like that of the zodiacal light a mystery one astronomer suggests that thai the phenomenon is due like the luminous redness of the eclipsed moon to the refraction by the earths atmosphere of sunlight which is made to converge in the shadow of the parth earth and is reflected in the one case by the moon and in the other by the dust that to is believed to be distributed throughout the ether spectroscopic evidence tends to prove that the conical zodiacal light which to is seen in the west after sunset in autumn and winter and in the east before sunrise in sunlight reflected from a ring of solid particles accompanying the earth the production of any desired variety of cheese by the introduction of the appropriate microbes mic robes Is gradually becoming

wholly cut off by night and eclipses |
