flinching Darwinian. His contributions to the discussion are varied and 

 valuable, and as collected in the present volume they will be seen to estab- 

 lish a claim upon the thinking world, which will be extensively felt and 

 cordially acknowledged. These papers not only illustrate the "history of 

 the controversy, and the progress of the discussionj but they form perhaps 

 the fullest and most trustworthy exposition of what is to be properly under- 

 stood by ' Darwinism ' that is to be found in our language. To all those 

 timid souls who are worried about the progress of science, and the danger 

 that it will subvert the foundations of their faith, we recommend the dis- 

 passionate perusal of this volume." — The JPopular Science MontliJ/y,

Heredity : A Psychological Study of its Phenomena, Laws, Causes, and 

 Consequences. From the French of Th. Bibot. 12mo. Cloth, $2.00. 

 " Heredity is that biological law by which all beings endowed with life 

 tend to repeat themselves in their descendants : it is for the species what 

 personal identity is for the individual. The physiological side ofthis subject 

 has been diligently studied, but not so its psychological side. We propose 

 to supply this deficiency in the present work." — From the IntrodMcHon.

 Hereditary Genius: An Inquiry into its Laws and Consequences. 

 By Francis Galton, F. R. S., etc. New and revised edition, with an 

 AJnerican Preface. 12mo. Cloth, $2.00. 



" The following pages embody the result of the first vigorous and me- 

 thodical effort to treat the question in the true scientific spirit, and place 

 it upon the proper inductive basis. Mr. Galton proves, by overwhelming 

 evidence, that genius, talent, or "whatever we term great mental capacity, 

 follows the law of organic transmission — runs in famuies, and is an affair or 

 blood and breed ; and that a sphere of phenomena hitherto deemed capri- 

 cious and defiant of rule is, nevertheless, within the operation of ascertain- 

 able law." — From the American Preface,

" The book has been translated into several languages. I hope that it 

 may also find sympathy in the fatherland of Dai-win, the more so since it 

 contains special morphological evidence in favor of many of the most impor- 

 t:'nt doctrines with which this greatest naturalist of our century has enridied 

 swonce." — Ihim the Preface.
