" Professor Bateson tells how Mendel's law works out with the colours 

 of certain flowers, moths, and canaries, and with colour-blindness in men 

 and women. More than this, he describes the outlook over this field of 

 research in a manner that will greatly interest and attract all intelligent 

 people, for, as he rightly says, ' Mendel's clue has shown the way into a 

 realm of nature which for surprising novelty and adventure is hardly to be 

 excelled.' " — Morning Post

It is commonly taken for granted that on this great problem — the 

 problem of Heredity — psychology can have nothing to say. But the author 

 has come at length to think that, provided we look at the world from what 

 he would call a spiritualistic and not from the usual naturalistic standpoint, 

 psychology may show us that the secret of heredity is to be found in the 

 facts of memory.
