THE EVOLUTION OF THE HORSE 

 Thomas Henry Huxley 



[Professor Huxley as a naturalist, educator, and contro- 

 versialist was one of the commanding figures of the nine- 

 teenth century. To physiology and morphology his re- 

 searches added much of importance: as an expositor he stood 

 unapproached. As the bold and witty champion of Dar- 

 winism he gave natural selection an acceptance much more 

 early and wide than it would otherwise have enjoyed. In 

 1S76 he delivered in America three lectures on Evolution: 

 the third of the series is here given. All three are copy- 

 righted and published by D. Appleton & Co., New York, in 

 a volume which also contains a lecture on the study of 

 biology. Since 1876 the arguments of Professor Huxley 

 have been reinforced by the discovery of many fossils con- 

 necting not only the horse, but other quadrupeds, with 

 species widely different and now extinct. The most com- 

 prehensive collection illustrating the descent of the horse 

 is to be seen at the American Museum of Natural History, 

 New York, where also the evolution of tapirs, camels, llamas, 

 rhinoceroses, dinosaurs, great ground sloths and other animals 

 are clearly to be traced — in most cases by remains dis«. 

 in America. A capital book on the theme broached by 

 Professor Huxley is "Animals of the Past," by Frederic 

 A. Lucas, Curator of the Division of Comparati 

 United States National Museum, Washington, D. C, pub- 

 lished by McClure, Phillips & Co., New York. 



"The Life and Letters of Professor Huxley," edited by 

 his son, Leonard Huxley, is a work of rare interest: it is 

 published by D. Appleton & Co., New York.fl
