Works of Charles Darwin. 



JOURNAL OF RESEARCHES into the Natural History and Ge- 

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

 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 the 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. Darwin's transparent, eloquent style richly illuminates 

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

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

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

 Northwestern Christiaft A dvocate. 



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 voy- 

 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 present 

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

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



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

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

 ume. 688 pages. Price, $3.00. 



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

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

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

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

 out doing violence to faith." — Evening Bulletin. 



THE EXPRESSION OF THE EMOTIONS IN MAN AND 



the Lower Animals. With Photographic and other Illustrations. 1 vol., thick 



izmo. 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 it. " — London Tinies. 



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

 Cloth. Price, $2.00. 



" In conclusion, we lay this book down with increased admiration for Mr. Darwin 

 as a discoverer and expositor offacts, and with great satisfaction at the increase to our 

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

 tions as the direct; consequence of the present pubHcation." — London Athenceiim. 



"In this work Mr. Darwin'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 displays 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 as 

 the professional student." — N. Y. Times.
