The book is an attempt to show the vast changes which have taken place 

 in the methods and scope of astronomy during the last quarter of the century 

 — changes so far-reaching that their full import has not yet been realized by 

 astronomers themselves. 



" The imperfect precis which we have been able to give of Professor Turner's 

 luminous and instructive work will, we can only trust, send the reader to that 

 work itself to perfect his information. Assuredly from no other extant will he 

 be able to derive so clear and intelligent an idea of the capital advances made 

 in modern astronomy." — The Observatory. 



" He writes with the clearness of a mathematician and the warmth oJ an 

 apostle, desirous, above all things, in the interest of the science he loves." — 

 Academy.
