...show that the spot has increased in size during the last three years. Professor W.H. Pickering, who made the observations, believes that the explanation of the change in the size of the spot is that Linne is more active than heretofore, and that there is therefore surrounding it more vapor, which produces the brighter reflection of light...
...electricity on the spectra of various gases. Although great care was taken in drying and pur fying these gases, it was found that hydrogen, nitrogen and rarefied air gave substantially the same spectrum under the same conditions and as a result of the powerful electrical discharges the aqueous vapor was released from the walls of the spectrum tubes. From this investigation it was concluded that oxygen does exist in the atmosphere of the sun. It was also found by a similar study of aqueous vapor in the X-ray phenomenon that, probably by varying the conditions of the strength...
...flower may possibly be a mere combination of grass, a whiff of vapor; but it is not also far more? What is to be said of its beauty, of the mystery surrounding its growth? The cross itself is but a couple of beams; but does this tell of it as a refuge for the sinner, as a triumphant emblem of faith? Surely this faith is the real thing, worth having, not the power to analyze that of others. Science has its place, but it has also its limitations. For one thing, the spiritual life cannot be weighed or measured...
...last night before the Natural History Society. He talked a few minutes about the main features of cloud formation, and then showed by means of lantern slides a very fine series of cloud views taken from photographs. Clouds, said Mr. Ward, are formed by the cooling and condensation of vapor in the air. There are three different types which are classified roughly into three kinds, the cirrus, characterized by its swift motion and feathery appearance; the cumulus, composed of round heaped-up masses; and the stratus, or low ground clouds, such as rise from valleys at night...
