COMPARATIVE LITERATURE. By HUTCHESON MACATTLAY 

 POSNETT, M. D., LL. D., Professor of Classics and English Literature, 

 University College, Auckland, New Zealand, author of " The Histori- 

 cal Method," etc. 12mo. Cloth, $1.75. 



" Scarcely a volume in ' The International Scientific Series ' appeals to a 

 wider constituency than this, for it should interest, men of science by its attempt 

 to apply the scientific method to the study of comparative literature, and men 

 of letters by its analysis and grouping of imaginative works of various epochs 

 and nations. The author's theory is that the key to the study of comparative 

 literature is the gradual expansion of social life from clan to city, from city to 

 nation, and from both of these to cosmopolitan humanity. His survey extends 

 from the rudest beginnings of song to the poetry of the present day, and at each 

 stage of his study he links the literary expression of a people with their social 

 development and conditions. Such a study could not easily fail of interesting 

 and curious results." Boston Journal 



MAMMALIA IN THEIR RELATION TO PRIMEVAL 

 TIMES. By Professor OSCAR SCHMIDT, author of "The Doctrine 

 of Descent and Darwinism." With ol Woodcuts. 12mo. Cloth, 



$1.50. 



"Professor Schmidt was one of the best authorities on the subject which he 

 has here treated with the knowledge derived from the studies of a lifetime. We 

 use the past tense in speaking of him, because, since this book was printed, its 

 accomplished author has died in the fullness of his powers. Although he pre- 

 pared it nominally for the use of advanced students, there are few if any pages 

 in his book which can not be readily understood by the ordinary reader. As 

 the title implies, Professor Schmidt has traced the links of connection between 

 existing mammalia and those types of which are known to us only through the 

 disclosures of geology." New York Journal of Commerce. 



" The history of the development of animals and the history of the earth and 

 geography are made to confirm one another. The book is illustrated with wood- 

 cut; 1 , which will prove both interesting and instructive. It tells of living mam- 

 malia, piijs, hippopotami, camels, deer, antelopes, oxen, rhinoceroses, horses, 

 elephants, sea-cows, whales, dogs, seals, insect-eaters, rodents, bats, semi-apes, 

 apes and their ancestors, and the man of the future. 11 Syracuse (N. Y.) Herald. 



ANTHROPOID APES. By ROBERT HARTMANN, Professor in the 

 University of Berlin. With 63 Illustrations. 12mo. Cloth, $1.75. 



"The anthropoid, or manlike or tailless, apes include the gorilla and chimpanzee 

 of tropical Africa, tho orang of Borneo and Sumatra, and the gibbons of the East 

 Indies, India, and some other parts of Asia. The author of the present work has 

 given much attention to the group. Like m ost living zoologists he is an evolutionist, 

 and holds that man can not have descended from any of the fossil species which have 

 hitherto come under our notice, nor yet from any of the species now extant; it is 

 more probable that both types have been produced from a common ground-form 

 which has become extinct 1 ' The Nation. 



"It will be found, by those who follow the author's exegesis with the heed and 

 candor it deserves, that the simian ancestry of man does not as yt rest upon such 

 solid and perfected proofs as to warrant the assumption of absolute certainty in which 

 materialists indulge." New York Sun. 



"The work is necessarily less complete than Huxley's monograph on 'The Cray- 

 fish,' or Mivart's on 'The Cat,' but. it is a worthy companion of those brilliant works? 

 and in saying this we bestow praise equally high and deserved." Boston Gazette.
