Huxley, Fort. Rev. 95, N. S. p. 564.) The whole is regarded 

 as the automatic action of the organism. Whether, if he had 

 been acquainted with the automatic action of the mind he 

 would not have resorted to that as an explanation of some 

 movements both animal and human, and among them probably- 

 some which he here mentions, is a question which I should

 whole subject, to answer in the affirmative. This matter will 

 occur in another connection. Meanwhile, though there may 

 be actions called sensori-motor, that have in them mental 

 elements, yet there are others that are, through the special sense 

 tracts though they be, as simply reflex as those through the 

 tracts of the general sensory system ; and these are, therefore, 

 equally with the latter, phenomena of irritability. It is to be 

 observed that the capacity for irritability is not exclusively 

 animal.

IN my two immediately preceding papers, the value of many 

 anonymous contributions to serial literature, on subjects 

 connected with Comparative Psychology, has been demonstrated 

 or estimated. 



We have now to estimate the value of anonymous contribu- 

 tions, on similar topics, to literature of a more permanent and 

 pretentious kind — of anonymous books, of all sorts and sizes, 

 treating of Animal Instinct or Intelligence. 



We begin with the bulky and expensive Cyclopedias, taking as 

 their type that, on the whole excellent one, of the Messrs. 

 Chambers of Edinburgh.* For general purposes it is superior 

 to the much more ponderous and costly " Encyclopaedia 

 Britannica," or indeed to any of its many rivals. The articles are 



' My remarks have reference to the first edition, of 10 volumes, published 

 between i860 and 1868, and to such articles as those on the Dog, Vol. III.; 

 Horse, Vol. V.; Elephant, Vol. IV; Camel and Cat, Vol. II.; Ant and 

 Bee, Vol. I. ; Spider, Vol. IX. A new or second and revised edition was 

 issued in 1874.
