Works of Charles Darwin. 



lOUKNAL OF RESEARCHES into the Natural History and Ge- 

 ology of the Countries visited during the Voyage of H. M. S. Beagle round the 

 World, under the command of Captain Fitzroy, R. N. i vol., i2mo. 579 pages. 

 Cloth. Price, $2.00. 



" Darwin was nearly five years on board the Beagle. A keen observer, and a genu- 

 ine philosopher, he has brought back to us a precious freight of facts and truths. The 

 work has been for some time before tlie public, and has won a high place among 

 readers of every class. It is not so scientific as to be above the comprehension of in- 

 telligent readers who are not scientific. Some facts and species, new even to the sci- 

 entific, are brought to light. iJarwin's transparent, eloquent style richly illummates 

 his observations. The weightier matters to which he alludes are interspersed among 

 more familiar observations, such as would naturally be made by a traveler passmg 

 through new and wonderful scenes. It is an instructive and interesting book." — 

 Northwestern Christian Advocate. 



THE ORIGIN OF SPECIES by Means of Natural Selection, or 



the Preservation of Favored Races in the Struggle for Life. New and revised edi- 

 tion, with Additions. With copious Index, i vol., i2mo. Cloth. Price, $2.00. 

 " Personally and practically exercised in zoology, in minute anatomy, in geology, 

 a student of geographical distribution, not in maps and in museums, but by long vo>;- 

 ages and laborious collection ; having largely advanced each of these branches of sci- 

 ence, and having spent many years in gathering and sifting materials for his pesent 

 work, the store of accurately-registered facts upon which the author of the 'Ongin of 

 Species' is able to diaw at will, is prodigious." — Prof. T. H. Huxley. 



THE DESCENT OF MAN, and Selection in Relation to Sex. 

 With lUustr.itions. New edition, revised and augmented. Complete in one vol- 

 ume. 683 pages. Price, $3.00. 



"This theory is now indorsed by many eminent scientists, who at first combated 

 it including Sir Charies Lyell, probably the most learned of geologists, and even by 

 a class of Christian divines like Dr. McCosh, who think that certain theones of cos- 

 mogony, like the nebular hypothesis and the law of evolution, may be accepted with- 

 out doing violence to {seiX!^.."— Evening Bulletin. 



THE EXPRESSION OF THE EMOTIONS IN MAN AND 



the Lower Animals. With Photographic and other Illustrations, i vol., thick 



i2mo. Cloth. Price, $3.50. 



" Whatever one thinks of Mr. Darwin's theory, it must be admitted that his great 

 powers of observation are as conspicuous as ever in this inquiry. During a space of 

 more than thirty years, he has, with exemplary patience, been accumulating informa- 

 tion from all available sources. The result of all this is undoubtedly the collection of a 

 mass of minute and trustworthy information which must possess the highest value, 

 whatever may be the conclusions ultimately deduced from \t."— London Times. 



INSECTIVOROUS PLANTS. With Illustrations. I vol., i2mo. 



Cloth. Price, $2.00. 



" In conclusion, we lay this book dowi with increased admiration for Mr. Dar^vin 

 as a discoverer and expositor of facts, and with great satisfaction at the increase to oiir 

 knowledge of plant physiology given us, as well as the ample promise of further addi- 

 tions as the direct consequence of the present publication."— i^««rfc« Athenaeum. 



"In this work Mr. Dar\vin's patient and painstaking methods of investigation ap- 

 pear to the best possible advantage. It is impossible to read it without enthusiastic 

 admiration for the ingenuity which he displ.ays in devising tests to determine the char- 

 acteristics of the plants, the peculiarities of which he is studying, and, as is always 

 the case with him, he presents the conclusions arrived at in language so lucid that he 

 who reads simply for information is sure to be attracted and charmed quite as much asi 

 the professional student." — N. V. Tunes.
