Book excerpt: Excerpt from Observations of Variable Stars Made During the Years 1901-12 The present publication contains the observations of variable stars made at the Vassar College Observatory under the directorate of Prof. Mary W. Whitney, 1888 - 1912. The earliest of these Observa tions were made during the winter of 1894 - 5, but they were somewhat experimental in character and soon gave way to micrometric work consisting chiefly of Observations of asteroids and comets. As Prof. Whitney had always retained her interest in variable stars, they were again placed on the observing program in 1901, and she continued working in this line until interrupted by illness in 1910. They were begun by the writer in 1909, and other contributions have been made from time to time by assistants and students connected with the Observatory. The results have been published at intervals in the Astronomische Nach'richten, and Astronomical Journal, generally in the form of Maxima and Minima of Long Period Variables, but without including the individual Observations. At the invitation of Prof. Pickering, many observations have been sent to the Harvard College Observatory, and together with those from other contributors have been published in H. C. 0. Annals, vols. 57 and 63. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
