not exist as realities. " Unless parents transmitted 

 to offspring their organisations, their peculiarities, and 

 excellences, there would be no such thing as a breed 

 or a race. The cur would run the same chance as 

 the best bred dog, of turning out valuable. The grey- 

 hound might point, and the cart-horse win the Derby. 

 Daily experience tells us that this is impossible. 

 Science tells us that there is no such thing as chance. 

 Physiology tells us that the offspring always, and 

 necessarily, inherits its organisation from its parents ; 

 and if the organisation is inherited, then with it 

 must be inherited its tendencies and aptitudes." 1 

 This, from one profoundly versed in physiology, 

 expresses what any one, not labouring to establish 

 some preconceived theory, will at once recognise as 

 the real state of the case. And, indeed, since struc- 

 ture and function are inseparably connected, since 

 diversity of structure necessarily supposes diversity 

 of function, and similarity of structure similarity of 

 function ; it follows that, as like produces like, in the 

 case of structural forms, so also must like produce 

 like in the case of functional peculiarities ; and as the 

 nervous system is but a part of the organism, and 

 must come under the same generalisation as the whole, 

 so also does the same hold true of the functions
