ming. The fact is, however, not that the younor 

 cuttle-fish is so especially clever, but that the young 

 cat is especially helpless, as a result of the mother's 

 care exercised throughout untold generations. The 

 apparent absence of instinct in the human being is 

 to be similarly explained : we have lost our physical 

 instincts because we do not need them in the pro- 

 tected condition which our social order affords us. 

 But they have not really disappeared, they have only 

 for the most part shifted their ground, and trans- 

 ferred themselves to the region of mental experience, 

 since with us the struggle for existence is for the 

 most part mental now, rather than physical. Hence 

 human instincts are such as have been already 

 named. The Eev. Gilbert White included musical 

 memory in the list of human instincts, and perhaps 

 with some reason, for talent of each kind, hereditary 

 as it certainly is, seems to be the cumulative product 

 of ancestral experience. In short, instead of drawing 

 a sharp line between the reasoning powers in man 

 and animals, -sye must recognise that they are the 

 same in kind, though varying in degree and a.pplica- 

 tion, according to the structure and mode of life of 

 each Icind.
