934. SENSES OF INSECTS. 
really seven senses; which he divides into those that are 
altogether physical, and those that are more connected 
with the intellect. The first of these divisions contains 
four senses,—touch, love, taste, and smell ;—the second 
three,—hearing, sight, and the internal sense of thought, 
or the brain?. That he is right in adding Jove? to the 
list seems to me evident, because it is as distinct from 
touch, as smelling and taste are. With regard to the 
other, though it may be expected that there should be 
a transitive sense connecting the intellect (if I may so 
speak) with the external organ of sense, and as a medium 
by which the former can receive the notices of the external 
world furnished by the latter ; yet it seems improper to 
make the entire brain itself a sense. We know that the 
agent between the common sensory and the sense is the 
consciousness or perception of the impression. ‘“ Seeing 
we may see and not perceive, and hearing we may hear and 
not widerstand.” ‘The picture may be painted upon the | 
retina of the eye, the sound may strike upon the tympa- | 
num of the ear; but neither the one nor the other be re- 
ceived by the intejlect, unless the internal power or fa~- 
culty of perception be in action and mediate between 
them. This is what I mean by the internal sense, which, 
to use a term of Mr. W. S. MacLeay’s*, is osculant be- 
tween intellect and sense, or forms the transit from one 
group of powers to the other. 
Of the ordinary senses, sight holds the first rank: it 
can dart to the region of the stars, and convey by the
