Fa ANIMAL INTELLIGENCE 
By inherited instinct, as well as by all those life 
experiences which had taught them that quiet and 
concealment of their usual activities were associated 
with escape from threatened evils, these little animals 
were naturally led, under the unwonted circumstances 
of their confinement, to disguise, in an extraordinary 
degree, their real condition, and even to imitate an 
unusual and unreal one. The mental process is a 
complex of instinct pure and simple, with higher 
intellectual factors added, and the cases of these 
squirrels, thus feigning, are among the clearest that, 
so far as I am aware, have ever been recorded. The 
adaptations to effect escape prove that there was the 
employment of intellectual processes of a pretty high 
order, possibly too complex, however, for analysis with 
safety, but not beyond realisation in our own conscious- 
ness, and without the employment of any abstract idea 
of death. 
That, however, the hypnotic element may play a 
part in the apparent feigning of death by squirrels 
seems clear from a case communicated to me by a 
student of the Montreal Veterinary College, Mr Craig. 
He had caught a Chipmunk and placed it in a box, 
to find in a few moments that it was lying as if dead. 
Giving the creature liberty to escape, it presently did 
so. On recapture the same followed. Considering the 
relatively low intelligence of this species of squirrel, 
and taking into account the case that Dr Romanes 
mentions of his watching an apparently feigning 
squirrel he had caught when he found that it had 
really died of fright, it seems to me, upon the whole, 
most reasonable to attribute the behaviour of the 
Chipmunk in question to cataleptic or allied effects. 
It thus becomes manifest how varied, and also how 
complex, these cases of so-called feigning may be. 
The subject is all the more interesting because it shows
