118 same time, and the telescope tube, which is being made by Messrs. Warner and Swasey, of Cleveland, will be ready in June, 1887. The trustees only await the mounting of this instrument, to turn over the observatory formally to the University of California. Meanwhile the observatory, as it now stands, with a twelve-inch Clark equatorial, a six-inch equatorial, a six-inch Repsold meridian circle, photographic instruments, clocks, chronometers, and all accessory apparatus, and an extensive library, is far better equipped than most observatories, and Professor Holden, with characteristic energy, has already begun an extensive series of observations with the meridian instrument, and has established a time-service for the benefit of the railroads connecting with San José.

This brief sketch merely attempts to outline Professor Holden's career as an astronomer. His administrative experience and ability were proved at Madison, and as a teacher he seems to have shown the rare faculty of arousing the enthusiasm of his pupils. His general interest in many matters outside of his profession may be seen by a glance at the partial list of his writings which is appended. This bibliography I have made tolerably full, though by no means exhaustive; I have found nearly one hundred papers, etc., contributed to scientific journals and transactions between the years 1873 and 1886; and the titles that I have given will form in themselves an effective "sketch" of his work. His life of Sir William Herschel should be referred to especially: it has been published in London as well as in New York, and has also been translated and published in Germany. A text-book of astronomy, published in co-operation with Professor Newcomb, has likewise been favorably received, and has passed through several editions.

In 1879 Professor Holden received the degree of A.M. from his alma mater, and the University of Wisconsin has just conferred the degree of LL.D. on its former professor. He is a member of the California and Wisconsin Academies of Science, Fellow of the American Association for the Advancement of Science, member of the Philosophical Society of Washington, and of the German Astronomische Gesellschaft, Corresponding Member of the Academy of Science of St. Louis, Associate Fellow of the American Academy of Arts and Sciences, Foreign Associate of the Royal Astronomical Society, and member of the National Academy of Sciences. While at Madison he was connected with Professor Raphael Pumpelly's Northern Trans-continental Survey, as head of the Division of Climate and Rivers, and in 1885 he served as a member of the Board of Visitors to the United States Military Academy at West Point.
