FACULTIES OF THE MIND. 299 
I have thus exhibited a few examples of perverted ana- 
logy, amidst many others equally obvious which might 
have been produced. The science of zoology abounds 
with them. I have already referred to a few, and shall 
have occasion afterwards frequently to return to the sub- 
ject. 
The inferior animals are, in many cases, deceived by ana- 
logy, as in the case of baits,—considering the identity as 
perfect, when there are only a few points of resemblance. 
2. Time.—It is probable that our notion of Time, is 
derived from a comparison of the succession of our ideas, as 
they spontaneously or voluntarily pass through the mind, 
with the succession of impressions produced by external 
objects. In looking at the commencement and conclusion 
of a change in one body, as the hour-hand of a clock, we 
find, that before it can exhibit a sensible change of place, 
several ideas can pass through the mind; but in the case 
of a cannon ball, an obvious change of place has been pro- 
duced before a single idea can be contemplated by the 
mind. The one moves slower, the other faster than thought. 
Our ideas of time and motion, therefore, are cotemporary. 
The rapidity with which the mind performs its intellectual 
processes, differs among men in different individuals, and in 
the same individual at different times,—an interesting idea 
being contemplated much longer than one to which we are 
indifferent. The succession of ideas therefore is irregular. 
The standard of time is sought for in the succession of 
changes of the material world. In an uncivilised state, 
man employs as his chronometer, the motions of the heaven- 
ly bodies,—the changes of day and night,—the seasons,— 
the moon,—and the tides. 
The inferior animals evidently have a knowledge of 
time. Those which leave a particular dwelling at stated
