has recorded some interesting facts connected with the 

 lower animals, and associated with hybridism. Thus he 

 says : "The swine has a very strong liking for barley; the 

 wild boar will not touch it, feeding on herbage and leaves. 

 From a cross between a domestic sow and a wild boar came 

 young, some of which have an aversion to barley, like the 

 wild boar, while the others have a taste for it like the 

 common hog." In the case of man also, many men, 

 individuals as well as families, have a defective sense of 

 taste, whilst in the case of others, the sense may be most 

 sensitive and refined. Some, on the other hand, have an 

 inherent and marked dislike for certain flavours ; and all 

 these peculiarities, of whatever grade, are emphatically 

 hereditary. Many facts might be given in support of this 

 latter assertion ; also with regard to the transmission of a 

 positive distaste for certain articles of food, as cheese, an 

 inherent liking for vegetable, and repugnance for animal food, 

 or vice versd, etc. I have, however, quoted sufficient facts 

 to show that "there is such a thing as heredity of the 

 perceptive faculties, even under the individual form ; " and 

 that in animals, " the quantity and quality of the perceptive 

 faculties will be certainly transmitted in their specific form, 

 and very probably, too, in their individual form ; therefore 

 heredity is the rule." Whether the highest forms of 

 intellectual faculties and activities are subject to the law of 

 heredity, I shall now proceed to consider. 



The functions of the cerebral hemispheres are those of the 

 organs by which the mind (i) perceives those clear and 

 more impressive sensations which it can retain, and accord- 

 ing to which it can judge ; (2) performs those acts of will, 

 each of which requires a deliberate, however quick, deter- 

 mination ; (3) retains impressions of sensible things, and
