The name of the distinguished author of this work is a sufficient pass- 

 port to public favor and a sure guarantee to its sterling value, and those 

 who have read Dr. Dick's former works will need no recommendation of 

 this book by us. He is not only an original and profound observer of na- 

 ture, but truly a most excellent Christian philosopher, whose powers of in- 

 tellect and expanded views of the character of the great Architect of the 

 universe are so eminently calculated to direct the mind not alone to the 

 grandeur, the magnificence, and sublimity of the laws and principles of 

 the material world, but to look through nature up to " Nature's God.'' It 

 is truly a valuable work. Farmer and Mechanic. 



The merits of this work are of the highest order; Dick is one of the 

 profoundest and purest of modern philosophers. Western Continent. 



Here is the ninth volume presented by this gifted author to the public ; 

 he aim of all of which has been to simplify sciences which before have 

 been too often considered as every way above, and therefore unworthy of 

 the attention of ordinary readers. It is specially addressed to private stu 

 dents and the higher schools, and comprises a large amoUnt of new and 

 valuable matter connected with astronomy, and pointing out ways in which 

 the more humble student can in the best way improve the advantages placed 

 in his way. Auburn Journal. 



Let not the inquisitive fear that the intricacies qf science or the techni- 

 calities of language will obstruct the pleasure they will derive from the 

 study of this book ; for the clearness of the author's style, and the elucida- 

 tion of the one hundred engravings, render it within the scope and compre- 

 hension of every intelligent student. Industrial Record. 



The copious use of engravings and of pictorial illustrations, together with 

 the plain, popular explanations, render this book a truly practical work. 

 Dr. Dick is not only thoroughly scientific, but he knows well how to render 

 his acquisitions available to the great body of common readers, by his ac- 

 curate method and clear descriptions. Watchman. 



We have always been an admirer of the writings of this gentleman, and 

 popularity keeps on his side wherever he is known. He is a profound 

 thinker and a devout Christian. His works all tend to illustrate the simple 

 as well as the sublimest principles of philosophy, and while they instruct, 

 can not fail to enlighten. The present volume comprises illustrations or 

 light and colors, practical descriptions of all kinds of telescopes, the use of 

 the equatorial-transit, circular, and other astronomical instruments, and 

 other topics connected with astronomy. It is illustrated by 100 engrav- 

 ings, and will be found a most valuable book for all classes, but particularly 

 as a work of instruction for youth. Illustrated Magazine.
