limitations as are the form and physical features of the whole organic 

 world. I shall show that social agencies of an ordinary character, 

 whose influences are little suspected, are at this moment working 

 towards the degradation of human nature, and that others are 

 working towards its improvement. The general plan of my argu- 

 ment is to show that high reputation is a pretty accurate test of/tigh 

 ability ; next, to discuss the relationships of a large body of fairly 

 eminent men, and to obtain from these a general survey of the laws 

 of heredity in respect of genius. Then will follozu a short chapter, 

 by way of comparison, on the hereditary transmission of physical 

 gifts, as deduced front the relationships of certain classes of oarsmen 

 and wrestlers. Lastly, 1 shall collate my results and draw conclu- 

 sions." The Times calls it "a most able and most interesting 

 book;" and Mr. Darwin, in his " Descent of Man" (vol. i. p. in,), 

 says, ' ' We know, through the admirable labours of Mr. Gallon, 

 that Genius tends to be inherited. "
