Q94 PHILOSOPHY OF ZOOLOGY. 
Without this faculty we would neyer even attempt to know 
what a day might bring forth. 
The mind appears to retain, and the memory to recall, 
both the retrospective and the prospective ideas which the 
imagination has formed ; and, what may appear surprising, 
the latter with the greatest readiness. This faculty, like 
those of attention and memory, is greatly improved by ex- 
ercise, and appears in the greatest degree of perfection in 
those who have received a liberal education, and habituated 
themselves to attend to their intellectual operations. In 
the savage state, this faculty is probably chiefly occupied in 
prospective efforts to secure food or shelter. 
In the lower animals, the faculty of the imagination cer- 
tainly exists, although, from the imperfect communication 
which subsists betwixt us and them, its operations, as distinct 
from memory, cannot be traced with any degree of certainty. 
The pointer, who exhibits impatience to travel when his 
master takes his gunin his hand, recollects the pleasure of his 
former sports, and wishes to have them renewed. What is 
it but imagination that persuades him that they may return, 
and even points out the channel of their course! A dog 
howls when his master is absent, and will anxiously look for 
his return in particular directions. Here is anticipation of 
a future event; and action founded on the certainty of its 
occurrence. We have seen a dog, evidently entertaining 
suspicions that his master would prevent him being a com- 
panion in his journey, steal away unobserved, and wait 
on the road, at a considerable distance from the house. 
Here we have the anticipation of the master’s going 
from home; apprehension of being detained; the pro- 
spect of gratification from the journey; an expectation of 
his master’s road; and the success which would crewn the 
plan ;—all of these efforts of the imagination. As we de- 
scend in the scale, these displays of the imagination can
