INSTINCT 17 



in. (ON VARIATION IN INSTINCTS AND OTHER 



MENTAL ATTRIBUTES.) 



The mental powers of different animals in wild 

 and tame state [present still greater difficulties] 

 require a separate section. Be it remembered I have 

 nothing to do with origin of memory, attention, and 

 the different faculties of the mind 1 , but merely with 

 their differences in each of the great divisions of 

 nature. Disposition, courage, pertinacity (?), sus- 

 picion, restlessness, ill-temper, sagacity and (the) 

 reverse unquestionably vary in animals and are 

 inherited (Cuba wildness dogs, rabbits, fear against 

 particular object as man Galapagos 2 ). Habits purely 

 corporeal, breeding season &c., time of going to rest 

 &c., vary and are hereditary, like the analogous 

 habits of plants which vary and are inherited. 

 Habits of body, as manner of movement d. and 

 d. Habits, as pointing and setting on certain 

 occasions d. Taste for hunting certain objects 

 and manner of doing so, sheep-dog. These are 

 shown clearly by crossing and their analogy with 

 true instinct thus shown, retriever. Do not know 

 objects for which they do it. Lord Brougham's 

 definition 3 . Origin partly habit, but the amount 

 necessarily unknown, partly selection. Young 

 pointers pointing stones and sheep tumbling 

 pigeons sheep 4 going back to place where born. 



! The same proviso occurs in the Origin, Ed. i. p. 207, vi. p. 319. 



2 The lameness of the birds in the Galapagos is described in the Journal 

 of Researches (1860), p. 398. Dogs and rabbits are probably mentioned as 

 cases in which the hereditary fear of man has been lost. In the 1844 MS. 

 the author states that the Cuban feral dog shows great natural wildness, 

 even when caught quite young. 



3 In the Origin, Ed. i. p. 207, vi. p. 319, he refuses to define instinct. 

 For Lord Brougham's definition see his Dissertations on Subjects of 

 Science etc., 1839, p. 27.

 Sketches, p. 403.
