152 ANIMAL INTELLIGENCE 



with first of all a dazed sort of expression, then one of 

 great surprise and enquiry, followed shortly by her 

 throwing herself upon me with a bark, almost a shriek 

 of joy. She passed through all the stages the puppy 

 manifests, but with those added ones coming from 

 -enlarged experience and a richer psychic life. 



The part smell plays in the ordinary and extra- 

 ordinary life of the dog is a most interesting and by 

 no means exhausted subject, which, though tempting 

 to pursue, is somewhat aside from the scope of the 

 present paper. 



As illustrating the development taste undergoes in a 

 few days, special attention is called to the accounts 

 given on the 28th, 31st, and 34th days. 



Experiments on taste might have been made at an 

 earlier date, but this omission was supplied in the case 

 of another litter of puppies to which reference will be 

 found in extracts from a diary introduced later. 



Some references to smell, as it influences habits, even 

 in very young puppies, have been referred to in the 

 diary. 



In the dog, much more than in the man, are smell 

 and taste associated, and this becomes evident in the 

 early as well as the later psychic life of this animal, 

 as shown by the diary, though this is like many other 

 features, much more evident to the one who daily 

 associates with animals, than it can be from the best 

 description it is possible to write. 



VISION. Owing to the gradual opening of the eyes, 

 it is difficult to see the pupil, and to make observations 

 on the reaction of the iris to light. Apart from this, 

 the record of the development of vision will, it is 

 hoped, be found pretty complete. 



The " opening of the eyes " is really a separation of 

 the lids, which are practically one at birth, by a process 

 of growth and absorption along the line of their future
