=A Year at Harvard Observatory.=--The director of Harvard College Observatory reports the addition to the resources of the institution of twenty thousand dollars bequeathed by Charlotte Maria Haven, and twenty-five thousand dollars by Eliza Appleton Haven, without further restriction in the application of the income than that it shall be for direct purposes connected with astronomical science. In these bequests the legators fulfilled the wishes of their brother, Horace Appleton Haven, as expressed half a century ago. By the peculiar organization of the force of the observatory, with a single director to oversee all and a large force of assistants, each having a special work and many of them skillful only in that, an increased amount of work can be done for a given expenditure, and great advantages for co-operation are secured, but too much depends upon a single person--the director. In the examination of the spectra of stars photographed in the Draper, Bruce, and Bache telescopes by Mrs. Fleming, twelve new variable stars were discovered by means of their bright hydrogen lines, and the spectra of a considerable number of other stars were determined. Valuable results, obtained by other examiners, are mentioned. An instrument has been constructed by which prismatic spectra can be converted into normal spectra or any other desired change of scale can be effected. By photographs obtained of stars in the vicinity of the north pole material is believed to be furnished for an accurate determination of the constants of aberration, nutation, and precession. Sixteen circulars were issued during 1897-'98. When fifty of these circulars have been issued, a title-page and index are to be published for binding.
