Sir Edwin Arnold, during his visit to the Observatory, at the suggestion of Professor Campbell, looked through the great telescope upon the nebula in Orion. "I saw," he writes, "in the well-known region of 'Beta Orionis,' the vast separate system of that universe clearly outlined,--a fleecy, irregular, mysterious, windy shape, its edges whirled and curled like those of a storm-cloud, with stars and star clusters standing forth against the milky white background of the nebula like diamonds lying upon silver cloth. The central star, which to the naked eye or to a telescope of lower power looks single and of no great brilliancy, resolved itself, under the potent command of the Lick glass, into a splendid trapezium of four glittering worlds, arranged very much like those of the Southern Cross. "At the lower right-hand border of the beautiful cosmic mist, there opens a black abyss of darkness, which has the appearance of an inky cloud about to swallow up the silvery filigree of the nebula; but this the great glass fills up with unsuspecting worlds when the photographic apparatus is fitted to it. I understood Professor Holden's views to be that we were beholding, in that almost immeasurably remote silvery haze, an entirely separated system of worlds and clusters, apart from all others, as our own system is, but inconceivably grander, larger, and more populous with suns and planets and their starry allies." Professor John M. Schæberle, formerly of Michigan University, has discovered two or more comets, written much on solar eclipses, the "canals" of Mars, and the sun's corona. He, with Professor S. W. Burnham, went to South America to observe the solar eclipse of Dec. 21-22, 1889; and the former took observations on the solar eclipse April 16, 1893, at Mina Bronces, Chili. Professor Burnham catalogued over one hundred and ninety-eight new double stars, which he discovered while at Mount Hamilton. He, with Professor Holden and others, have taken remarkable photographs of the moon; and the negatives have been sent to Professor Weinek of Prague, who makes enlarged drawings and photographs of them. Astronomers in Copenhagen, Vienna, Great Britain, and other parts of Europe, are working with the Lick astronomers. Star maps, in both northern and southern hemispheres, have been made at the Lick Observatory, and photographs of the milky way, the sun and its spots, comets, nebulæ, Mars, Jupiter, etc. Professor Holden has written much in the magazines, the _Century_, _McClure's_, _The Forum_, and elsewhere, concerning these photographs, "What we really know about Mars," and kindred topics.
