Lockyers Astronomy. 



AMERICAN EDITION. 



"This is by far the clearest and best manual of Astronomy we 



have ever seen. A child may understand it— and yet 



it contains information which will be new to 



all who have not time to follow the 



latest discoveries." — jSew 



York Daily Times. 



The opinion of the critic of the Thnes^ given above, 

 is that of all who have examined this sterling school- 

 book, which is winning golden opinions everywhere. 

 Out of hosts of letters, we have space for the following 

 only : — 



" Lockyer's Elements of Astronomy is a -work of rare excellence. As a text-book for 

 the use of schools it is unsurpassed by any work on that subjuet with which I am ac- 

 quainted .''—Pkof. John 8. Hajrt, State Xormal School, Trenton, IT. J. 



'■ I think it an excellent work— \vell calculated for class use b}- pupils of an academic 

 |rade. The arrangement and typography are worthy of especial conmiendation. It is 

 a decided success."— S. E. Howe, SupL of Schools, Schenectady, N. Y. 



"It is the best school-book on Astronomy that I ever saw. The spectra of the sun, 

 stars, and nebulae, are worth the price of the book. The diagrams are excellent. I 

 deem it superior to all other books on that science with which I am acquainted. Of 

 course I shall use it." — W. H. Pitt, A. M., Prlnc. Friendtildp Academy. 



"I have examined with much satisfaction the admirable elementary treatise on As- 

 tronomy by Lockyer. It furnishes the reader with the means of learning in a short 

 time the great features of the modern progress of Astronomy. No book (except, per- 

 haps, Toumans's New Chemistry) has appeared, which so easily, yet thoroughly, pre- 

 pares the reader for the subsequent study of that mighty auxihary to modern science — 

 spectrum -analysis. Moreover it presents, in a clear and succinct style, the relations of 

 the various parts of the stellar imiverse, besides inducting the learner into that neglected 

 branch of Astronomy known as Geography of the Heavens. Its illustrations are genu- 

 ine aids to the comprehension of the subject-matter." — David Beattie, Siipt. Troy 

 XN Y) City Schools. 



" I have examined it -with care, and find it admirably adapted for use in schools. It 

 is so plainly written and so fully illustrated as to render it specially suited for beginners 

 in the science,- and, at the same time, ptofitahle for advanced students." — Peof. C. Sta' 

 LEY, Union College. 



"It is a clear and beautiftil unfolding of a profound and fascinating subject. -It 

 seems to me admirably adapted to the academic grade of students. Not attempting to 

 discuss those problems and theories of the science for which such pupils have neither 

 the time nor the capacity, the author has given an outline of the subject that is clear, 

 sufficiently complete, and thoroughly modern."— Peof. Beadlet, Princ. Albany Pre* 

 A cadenvy.
