...visiting committee of the division of Geology has provided the department with the funds necessary to erect a seismograph in the University Museum. A Bash-Omori seismograph with two 100 kilogram conical pendulums, one swung in the meridian and the other east and west, will shortly be placed on a suitable foundation in the basement of the Geological section. This type of instrument records earth vibrations on smoked paper carried on revolving drums operated by clockwork. One of the same general type which has been set up in the State Museum at Albany, New York, for more than a year...
Besides a large number of observations made with the East Equatorial and the meridian circle instruments both in Cambridge and at the station in Peru, observations have been made along new and unique lines of work with the Henry Draper Memorial instruments. First, the spectra of large numbers of stars have been photographed simultaneously, with the result that large numbers of objects having peculiar spectra have been discovered. Secondly, stellar spectra, six inches long, and showing several hundred lines, have been obtained, demonstrating that large numbers of stars have identical spectra. Thirdly, photographs of the entire sky have been taken...
...station in Arequipa, Peru, 3,919 photographs have been obtained by Professor Bailey with the 13-inch Boyden telescope. The meridian photometer has also been sent to Peru, for the observation of the Planet Eros. With the Bruce Photographic telescope, 6,174 plates have been exposed, including a large number of exposures of asteroids, several of which are probably new. One of these asteroids has a greater eccentricity than any one hitherto known, and has been named Odlo, after the Peruvian goddess. A photograph of Eros was obtained nearly a month before it was observed elsewhere after its conjunction with...
...sometimes years. The Observatory's first trial shows its brightness to have greatly increased by Friday night over that announced by Dr. Anderson for the preceding evening until on Friday it was much brighter than the polar star. The exact position on three nights has been measured with the meridian circle and the spectrum has been founed by a photographic attachment to the telescope. This has been found to have changed -- a result also obtained by the Lick Observatory...
...most interesting results of the year's work have been in the observations made with the meridian photometer, and in the experiments with kites at the Blue Hill Observatory. As a result of observations taken on 152 nights the total number of photometric settings is 100, 052, which is greater than that obtained in any previous year. The observations of all the stars north of 40 degrees, of the magnitude of 7.5 and brighter, are nearly completed. The exploration of the upper air with kites lifting automatic instruments which record atmospheric conditions has been continued. Last September records were brought...
