212 CONSCIOUSNESS IN 



The same dog, at Hastings, made a spring at a gentleman who 

 came into the hotel. The owner caught the dog and apologized, 

 and said he never knew him to do so before, except when a butcher 

 came to his house. The gentleman at once said that was his 

 business." 



This detection of butchers at a distance and out of 

 sight, as well as when disguised, could only have been 

 brought about through the dog's highly developed sense 

 of Smell, enabling it to detect odours which might well 

 be regarded as altogether inappreciable. 



In reference to a suggestion made by Mr. Wallace,* to the 

 effect that animals which have been taken to a distance 

 shut up in a basket, or along a route which they have not 

 seen, may, in some instances, find their way home princi- 

 pally through the intervention of their highly developed 

 sense of Smell (a suggestion which gave rise to a long and 

 very interesting discussion), Prof. Gr. Groom Eobertson 

 writes :f " Our external world (whether as actually 

 perceived or imaginatively represented) may be called a 

 world of sights and touches, blended with and modifying 



each other in the most intimate way All other 



sensations, as of hearing, smell, and taste, come before 

 us only discontinuously and intermittently, not being had 

 from all things, nor always from the same things. But, 

 in a dog's experience, touch cannot possibly co-operate 

 with sight, as it regularly does in ours. The organ of 

 effective touch in man touch that gets associated with 

 vision is, in the last resort, the hand, combining mobility 

 aud sensitiveness in the highest degree ; and the dog has 

 no hand. Its mobile limbs are not sensitive at the ex- 

 tremities, and, though it has sensitive lips, these, having 

 no such active mobility as the human hand has, are
