302 SENSITIVENESS. 



instance, in the dog. On the one hand, in various kindly, 

 considerate ways, it offers consolation to human sufferers ; 

 while, in its own griefs, it is sometimes inconsolable, discon- 

 solate refuses every kind of sympathy or consolation. 



Many animals show every shade of annoyance or displea- 

 sure. A feeling of mere displeasure will cause a pet and 

 petted dog to refuse food (Watson). The dog, or other ani- 

 mals, in proportion to their natural or morbid irascibility, 

 are annoyed, moreover, at trifles. In other words, they are 

 easily provoked, and the provocation may be altogether dis- 

 proportionate to its immediate or exciting cause. 



The irritability of the parrot its susceptibility to being 

 teased is well known to its admirers ; and the same may 

 be said of elephants, monkeys, and other menagerie ani- 

 mals, in whom such irritability is the result partly of cap- 

 tivity, partly of their habitual subjection to irritation from 

 man. 



Many animals suffer keenly from disappointment or mor- 

 tification of all kinds. Thus they show their disappointment 

 when thirsty at not finding water (Houzeau), or at the non- 

 gratification of other appetites, wants, or desires (Watson). 

 Birds, dogs, cats, and other animals manifest chagrin at 

 errors of all kinds committed by themselves, more especially 

 probably when they are by man detected in a fault, or are 

 otherwise by him convicted. 



So many examples have been given in other parts of this 

 book for instance, in such chapters as those on * The Bodily 

 Results of Mental Causes,' and on ' The Moral Causes of 

 Mental Disorder ' of the influence of such emotions, feel- 

 ings, passions as grief, terror, fright, anger, revenge, jealousy, 

 in all their degrees and forms, that it is unnecessary here to 

 recapitulate, further than simply to remind the reader that 

 their results include 



1. Death. 



2. Disease of various kinds mental as well as bodily. 



3. Sudden paralysis of thought and action. 



4. Eemarkable changes of character or disposition. 



5. Temporary or permanent colour-changes. 



6. Motor derangement.
