ANIMAL INTELLIGENCE. 
neously shown in the following case. It is communicated 
to me by a correspondent, Mr. A. H. Browning. This 
gentleman was looking at a litter of young pigs in their 
sty, and when he went away the door of the sty was in- 
advertently left unfastened. The pigs all escaped into 
his garden. My correspondent then proceeds : — 
My attention was called to my dog appearing in a great 
state of excitement, not barking (he seldom barks), but whining 
and performing all sorts of antics (in a human subject I should 
have said ‘ gesticulating ’). The herdmenand myself returned to 
the sty ; we caught but one pig, and put him back ; no sooner 
had we done so than the dog ran after each pig in succession, 
brought him back to the sty by the ear, and then went after 
another, until the whole number were again housed. 
In Lord Brougham’s 6 Dialogues on Instinct ’ (iii.) 
there is narrated the story told to the author by Lord 
Truro of a dog that used to worry sheep at night. The 
animal quietly submitted to be tied up in the evening, 
but when everybody was asleep he used to slip his collar, 
worry the sheep, and, returning before dawn, again get 
into his collar to avoid suspicion. I allude to this re- 
markable display of sagacity because I am myself able 
fully to corroborate it by precisely similar cases. A friend 
of mine (the late Mr. Sutherland Murray) had a dog 
which was always kept tied up at night, but nevertheless 
the neighbouring farmers complained of having detected 
him as the culprit when watching to find what dog it was 
that committed nightly slaughter among their sheep. My 
friend, therefore, set a watch upon his dog, and found 
that when all was still he slipped his collar, and after 
being absent for some hours, returned and slipped his 
head in again. 
A precisely similar case is given further back, and 
others are communicated to me by two correspondents 
(Mr, Groodbehere, of Birmingham, and Mr. Eichard Wil- 
liams, of Buffalo). The latter says : — 
And here let me ask if you are aware of the cunning and 
sagacity of these sheep-killing dogs, that they never kill sheep 
on the farm to which they belong, or in the immediate vicinity, 
but often go miles away ; that they always return before day*
