LECTURES ON LIGHT 



RECENTLY DELIVERED IN THE UNITED STATES. 



BY 



PROF. JOHN TYNDALL, LL.D., F.R.S. 



FULLY ILLUSTRATED AND WITH THE AUTHOR'S LATEST CORRECTIONS. 



Paper, 75 Cents; Cloth, $1,00, 



The author, on leaving England, had no intention of publishing these lectures ; but, 

 having been rewarded by the American people as no lecturer has ever been, and being un- 

 able to respond to the invitations of the cities of the West, thought it due both to those 

 who heard the lectures with such marked attention, and to those who wished to hear 

 them but were unable to do so, to leave them behind him in an authentic form. The en- 

 thusiasm with which the great scientist was welcomed by the cities of Boston, Washing- 

 ton, Philadelphia, Baltimore, Brooklyn, and New York, and the decided success cf his 

 present lectures, show, we think, both their timeliness and superior merit.
