cess was perfect long before. The same tests whicli prove the 

 intelligence of the child demonstrate its existence in animals. 

 There is a similar power of comprehending the wishes ex- 

 pressed, by associating certain articulate sounds with certain 

 acts requu-ed, as well as an equal recognition of the tones of 

 voice by which approval, reproof or anger are made known ; 

 but, lacking the organs of speech, they are debarred, and forever 

 must be, from any except the most limited interchange of thought. 

 For this reason, attentive study is needed in ascertaining the ex- 

 tent to which they comprehend and respond to the intelligence 

 which addresses them. 



In the case of wild or undomesticated animals there is little 

 opportunity for investigating this interesting subject. We see 

 the beaver build his dam, and we understand the object so ad- 

 mirably attained by hie work. We know that the elephant, to 

 be taken in the pitfall, must see on the earth that covers it the 

 foot-prints of one of his fellows, and we surmise the process of 

 reasoning by which he concludes that he is safe in venturing 

 where another of his kind has trodden. We learn that the 

 ostrich which in torrid regions trusts to the heat of the sand for 

 the incubation of her eggs, will in a more temperate latitude 

 supply the heat which would else be lacking by setting on her 

 eggs during the cooler nights ; but in none of these, nor in a 

 score of other cases, in which there seems a rational foresight, 

 can we determine how far the acts result from intelligent reflec- 

 tion. In domesticated animals, and especially in such as are 

 trained for the service of man, the action of intelligence may be 

 clearly traced; it is demonstrated by the ease and certainty 

 with which they can be educated ; it is seen in the readiness 

 with which many receive and act upon ideas communicated to 

 them ; and in a multitude of instances the mental process is 

 evident by which they have, independently, reached conclusions 

 rationally deduced from facts of their previous knowledge. 



Mr. J. Hopes relates a circumstance of a terrier who had been 

 temporarily left by his master in the care of a Mrs. Lanford at 

 St. Albans. This lady owned a large house-dog which, disliking 

 the presence ol the stranger, quarreled with him, biting and
