ANIMAL INTELLIGENCE. 
made the sign just described. His whole manner im- 
mediately altered to that of high animation. Clearing 
the wall together, the two animals ran down the road as 
terriers only can when pursuing an enemy. I watched 
them for a mile and a half, within wdiich distance their 
speed never abated, although the object of their pursuit 
had not from the first been in sight. 
It is almost superfluous to give cases illustrating the 
well-known fact that dogs communicate their desires and 
ideas to man; but as the subject of the communication 
by signs will afterwards be found of importance in con- 
nection with the philosophy of communication by words, 
I shall here give a few examples of dogs communicating 
by signs with man, which for my purpose will be the 
more valuable the less they are recognised as unusual. 
Lieutenant-Gren. Sir John H. Lefroy, C.B., K.C.M.Gk, 
F.E.S., writes me that he has a terrier which it is the 
duty of his wife’s maid to wash and feed. 4 It was her

The dog endeavoured in every possible way to attract her 
attention and draw her forth, and at last pushed aside the 
curtain of a closet, and never having been taught to fetch 
or carry, took between his teeth the cup she habitually 
used, and brought it to her feet. I inquired into every 
circumstance strictly on the spot, and was shown where he 
found the cupj 
Similarly I select the following case from a great 
number of others that I might quote, because it is so 
closely analogous to the above. It is communicated to 
me by Mr. A. H. Baines : — 
There is a drinking-trough for him in my sitting-room : if 
at any time it happens to be without water when he goes to 
drink, he scratches the dish with his fore-paws in order to call 
attention to his wants, and this is done in an authoritative way, 
which generally has the desired effect. Another Pomeranian — 
a member of* the same family— when quite young used to soak
