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.

Paperback. Zustand: New. Print on Demand. This book compiles observations of variable stars collected between 1901-1912 by the Vassar College Observatory. The author presents the results of these observations along with discussions of the methods and instruments used to collect them. The book provides valuable insights into the history of astronomy, as it documents a time when astronomers were transitioning from visual observations to photographic methods. This allowed for the study of fainter stars and contributed to a deeper understanding of stellar variability. The author's careful compilation and analysis of these observations make this book a valuable resource for astronomers and historians of science alike. Its detailed observations and discussions of variable stars offer a glimpse into the development of astronomy during a period of significant technological advancements in the field.
