IX REPULSION AND COUPLING 95 



phenomena of heredity in man few things are more striking 

 than the remarkable way in which children so often re- 

 semble this or that parent, not in one or two, but simul- 

 taneously in a number of characters. The human species 

 shows so many heritable features, and man is such a 

 mongrel, that it would be reasonable to look for relatively, 

 few points of resemblance between parent and oiifspring. 

 The fact that these are frequently so numerous suggests that 

 in man characters are transmitted as it were in bunches, 

 and it is not improbable that the study of cases in which 

 coupling occurs will eventually render clearer what is 

 evidently an important feature in the heredity of our own 

 kind.
