Note 4 — ON THE INTELLECTUAL SUPERIORITY WHICH MAN HAS ACQUIRED BY SPEECH, AND THE POSSESSION OF THE HAND.

The reader may refer to works on comparative anatomy, for information concerning this sense in animals. They all agree that no animal possesses a complete hand, and that the thumb is especially defective in size, and in the strength which enables it to act in opposition to the combined force of the fingers. The sense of touch in many animals appears to reside in the large and fleshy nostrils, which appear highly sensible; and it is also evident, that in these the touch has an intimate alliance with their sense of smell.
