 NEW AND IMPROVED EDITION.~(Now Ready.) 



OUTLINES OP ASTRONOMY. 



BY Sm JOHN F. ^Y. HERSCIIEL, F. E. S., &c. 



A NEW AMERICAN FROM THE FOURTH LONDON EDITION. 



In one very neat crown octavo volume, extra cloth, with six plates and nu- 

 merous wood-cuts. 



This edition will be found thoroughly brought up to the present state of as- 

 tronomical science, with the most recent investigations and discoveries fully 

 discussed and explained. 



We now take leave of this remarkable work, which we hold to be, beyond a doubt, 

 the greatest and most remarkable of the works in which the laws of astronomy and the 

 appearance of the heavens are described to those who are not mathematicians nor ob- 

 servers, and recalled to those who are. It is the reward of men who can descend from 

 the advancement of knowledge to care for its diffusion, that their works are essential 

 to all. that they become the manuals of the proficient as well as the text-books of the 

 learner. — Athentrum. 



There is perhaps no book in the English language on the subject, which, whilst it con- 

 tains so many of the facts of Astronomy (which it attempts to explain with as little tech- 

 nical language as possible), is so attractive in its style, and so clear and forcible in its 

 i\\asXrHUo]i-i.— Evnngtlic(d Revieio. 



Probably no book ever written upon any science, embraces within so small a compass 

 an entire epitome of everything known within all its various departments, practical, 

 theoretical, and physical.— ^xawmer.
