THE NEW ASTRONOMY. 



By S. P. Langley. I vol. Royal octavo. Il- 

 lustrated, $5.00. 



" The lover of a beautiful book will open ' The New 

 Astronomy ' and mark its completeness in all the quali- 

 ties of a perfect book. Its illustrations are admirable. 

 The author in his preface says : ' I have written these 

 pages, not for the professional reader, but with the hope of 

 reaching a part of that educated public, on whose support 

 he is so often dependent for the means of extending the 

 boundaries of knowledge ' " — Chicago Uiter'Ocean. 



'* A handsome, interesting, and valuable book. The 

 chapters on the moon and the planets are wonderfullyinter- 

 esting. There is both inspiration and solemnity in the 

 thought of man, with instruments of his own invention, 

 forcing the stars to reveal somethingof themselves, which 

 has been hidden from this earth since the creation ; pho- 

 tographing not only the lightning, but stars, tha 

 ible even to the telescope: and ever finding 

 more beyond. There are no words to tell of this vastness 

 of creation, or of the infinite hope and courage of the 

 human souls who set themselves to map out its form, to 

 solve its mysteries, to walk by knowledge among its suns 

 and stars." — Boston Post. 



A fascinating and instructive volume, giving the latest 

 ■discoveries and theories in Astronomical Science, with 

 nearly loo elaborate and beautiful illustrations. The fol- 

 lowing are the titles of the chapters, showing the scope 

 of the work : Spots on the Sun ; The Sun's Surround- 

 ings ; the Sun's Energy ; the Planets and the Moon ; 

 Meteors ; Comets ; the Stars. 



Prof. Langley's great scientific attainments have won 

 for him the high consideration of most distinguished 

 scholars throughout the world, and ensure for this work 

 the leading position among astronomical treatises. The 

 recent appointment of Prof. Langley to the Secretary- 

 ship of the Smithsonian Institution (to succeed the late 

 Prof. S. F. Baird) crowns a long series of honors from 

 American and foreign learned
