WORKS OF T. H. HUXLEY, F.R.S. 



On the Origin of Species; or, the Causes of the Phenomena of Organic Nature. 

 12mo. Cloth, fl.OO. 

 "The publication of Mr. Darwin's work on 'Tlie Origin of Species' must be looked upon as 

 marking an era in the progress of sciecce. but, while it called forth a due share of candid dis- 

 cussion and intelligent criticism, it has been vehemently and persistently assailed by many who 

 understood nothing of its real character ; and the subject lias hence been so overloadea with preju- 

 dice and perversion that unscientific people hardly know what to think or believe about ii. In 

 these circimistanc'is, those who disencumber the subject of its difficulties, simplily its statements, 

 relieve it of technicalities, and bring it so distinctly within the horizon of ordinary apprehen^ion 

 that persons of common sense mav judge for themselves, perform an invaluable service. Such 

 is the character ot the present voluine."— i^^ow the Preface tu the American Edition,.
