this restrains the activity of his sight to a limited distance, and a 
determined degree of light. His external ear, possessing but little 
mobility or extent, does not increase the intensity of sounds, and 
yet, of all animals, he best distinguishes the various degrees of in- 
tonation. His nostrils, more complicated than those of the Monkey, 
are less so than those of all other genera; and yet he appears to be 
the only animal whose sense of smell is sufficiently delicate to be 
affected by unpleasant odours. Delicacy of smell must have some 
influence on that of taste, and independently of this Man must have 
some advantage in this respect over other animals, those, at least, 
whose tongues are covered with scales. Lastly, the nicety of his 
tact results, both from the delicacy of his teguments, and the ab- 
sence of all insensible parts, as well as from the form of his hand, 
which is better adapted than that of any other animal for suiting 
itself to every little superficial inequality. 
Man is pre-eminently distinguished in the organ of his voice; of 
all the Mammalia, he alone possesses the faculty of articulating 
sounds, its probable causes being the form of his mouth and the 
great mobility of his lips. From this results his most invaluable 
mode of communication, for of all the signs which can be conveniently 
employed for the transmission of ideas, variations of sound are those 
which can be perceived at the greatest distance, and are the most 
extensive in their sphere of operation. 
The whole of his structure, even to the heart and great vessels, 
appears to have been framed with a view to a vertical position. The 
heart is placed obliquely on the diaphragm, and its point inclines to 
the left, thereby occasioning a distribution of the aorta, differing 
from that of most quadrupeds. 
The natural food of man, judging from his structure, appears to 
consist of the fruits, roots, and other succulent parts of vegetables: 
his hands offer him every facility for gathering them; his short, and 
but moderately strong jaws on the one hand, and his canini being 
equal in length to the remaining teeth, and his tubercular molares 
on the other, would allow him neither to feed on grass nor to deyour 
flesh, were these aliments not previously prepared by cooking. 
Once, however, possessed of fire, and those arts by which he is 
aided in seizing animals or killing them at a distance, every living 
being was rendered subservient to his nourishment, thereby giving 
him the means of an infinite multiplication of his species. 
His organs of digestion are in conformity with those of manduca- 
tion; his stomach is simple, his intestinal canal of moderate length, 
the great intestines well marked, his cecum short and thick and 
augmented by a small appendage, and his liver diyided | only into two
