The Story of the Sun.
By Sir Robert S. Ball, F.R.S., author of "An Atlas of Astronomy," "The Cause of an Ice Age," etc. 8vo. Cloth, $5.00.
"Sir Robert Ball has the happy gift of making abstruse problems intelligible to the 'wayfaring man' by the aid of simple language and a few diagrams. Science moves so fast that there was room for a volume which should enlighten the general leader on the present state of knowledge about solar phenomena, and that place the present treatise admirably fills."—London Chronicle.
An Atlas of Astronomy.
By Sir Robert S. Ball, F.R.S., Professor of Astronomy and Geometry at the University of Cambridge; author of "Starland," "The Cause of an Ice Age," etc. With 72 Plates, Explanatory Text, and Complete Index. Small 4to. Cloth, $4.00.
"The high reputation of Sir Robert Ball as a writer on astronomy at once popular and scientific is in itself more than sufficient recommendation of his newly published 'Atlas of Astronomy.' ... The introduction is written with Sir Robert Ball's well-known lucidity and simplicity of exposition, and altogether the Atlas is admirably adapted to meet the needs and smooth the difficulties of young and inexperienced students of astronomy, as well as materially to assist the researches of those that are more advanced."—London Times.
Studies in Spectrum Analysis.
By J. Norman Lockyer, F.R.S., Correspondent of the Institute of France, etc. With 60 Illustrations. 12mo. Cloth, $2.50.
"The study of spectrum analysis is one fraught with a peculiar fascination, and some of the author's experiments are exceedingly picturesque in their results. They are so lucidly described, too, that the reader keeps on from page to page, never flagging in interest in the matter before him, nor putting down the book until the last page is reached."—New York Evening Express.
