THE PLURALITY' 01? WORLDS. 



WITH AN INTRODUCTION by EDWABD HITCHCOCK, LL.D., President of 

 Ainherst College. 12uio, cloth. $1.00. 



Jfc= This 5s a masterly production on a subject of great interest. 



The " Plurality of Worlds" is a work of great ability, and one that cannot fail to arrest the 

 attention of the world of science. Its author takes the bold ground of contesting the generally 

 adopted belief of the existence of other peopled worlds beside our own earth. A gentleman 

 upon whose judgment we place much reliance writes, in regard to it : 



" ' The Plurality of Worlds ' plays the mischief with the grand speculation of Christian and 

 other astronomers. It is the most remorseless executioner of beautiful theories I have ever 

 stumbled upon, and leaves the grand universe of existence barren as a vast Sahara. The author 

 Is a stern logician, and some of the processes of argumentation are singularly fice. Many of 

 the thoughts are original and very striking, and the whole conception of the volume is as novel 

 as the results are unwelcome. I should think the work must attract attention from scientific 

 men, from the very bold and well-sustained attempt to set aside entirely the scientific assump- 

 tions of the age." Boston Atlas. 



This work has created a profound sensation 5n England. It is, in truth, a remarkable book, 

 remarkable both for the boldness of the theory advanced, and for the logical manner in which 

 the subject-matter i3 treated. Mercantile Journal. 



The new scientific book, Plurality of Worlds, recently published in this city, is awakening an 

 unusual degree of interest in the literary and scientific world, not only in this country, but in 

 England. The London Literary Gazette, for April, contains an able review, occupying over 

 nine columns, from which we make the following extract : "We venture xo say that no scien- 

 tific man of any reputation will maintain the theory, without mixing up theological with phys- 

 ical arguments. And it is in regard to the theological and moral aspect of the question, that 

 we think the author urges considerations which most believers in the truths of Christianity 

 will deem unanswerable." Evening Transcript. 



The "Plurality of Worlds" has created as great a sensation in the reading world, as did the 

 Testiges of Creation. But this time the religious world is not ur. in arms with anathemas on 

 its lips. This is a book for it to " lick its ear " over. It is aimeu at the speculations of Fonte- 

 nelle, or Dr. Chalmers, respecting the existence of life and spirit in the worlds that roll around 

 us, and demonstrating the impossibility of such a thing. London Cor. of JV. T. Tribune. 



To the theologian, philosopher, and man of science, this is a most intensely interesting work, 

 while to the ordinary thinker it will be found possessed of much valuable information. The 

 work is evidently the production of a scholar, and of one earnest for the dissemination of truth 

 In regard to what he considers, for theologians and scientific men, the greatest question of the 

 age. Albany Transcript. 



The work is learned, eloquent, suggestive of profound reflection, solacing to human pride, and 

 even to Christian humility j and points out the great lesson it illustrates, upon the diagram of 

 the heavens, in language and tone elevated to the standard of the great theme. Boston Atlas. 



One of the most extraordinary books of the age. It is an attempt to show that the facts of 

 science do not warrant the conclusion to which most scientific minds so readily assent, that 

 the planets are inhabited. The anonymous author is a genius, and will set hundreds of critics 

 on the.huut to ferret him out I Star of the West. 



GEOLOGICAL MAP OF THE UNITED STATES AND BRITISH PROV- 

 INCES OF NORTH AMERICA. With an Explanatory Text, Geological 

 Sections, and Plates of the Fossils which characterize the Formations. By 

 JULES MARCOU. Two volumes. Octavo, cloth. $3.00. 



J5~ The Map is elegantly colored, and done up with linen cloth back, and folded in octavo 

 form, with thick cloth covers. 



The most complete Geological Map of the United States which has yet appeared. The exe- 

 cution of this Map is very neat and tasteful, and it is issued in the best style. It is a work 

 which all who take an interest in the geology of the United States would wish to possess, and 

 we recommend it as extremely valuable, not only in a geological point of view, but as repre- 

 senting very fully the coal and copper regions of the country. The explanatory text presents a 

 rapid sketch of tne geological constilations of North America, and is rich in facts on the sub- 

 jects. It embellished with a number of beautiful plates of the fossils which characterize the 

 formations, thus making, with the Map, a very complete, clear, atvl distinct outline of the geology 

 tif our country Mining Mrtyazinf, N. Y. '"*"
