Consequently, in climbing the animal Post Date: Mon, 18 Aug 2008 13:06:43 +0000
(b) The feet also are constructed on the plan of the hand; ie, the large toe is opposable to the other toes, just as the thumb is to the other fingers. The large toe is very strong, and can be widely extended (like the thumb in the human hand), and the soles of the feet are turned, not downwards as in man, but obliquely inwards. Consequently, in climbing the animal is able to grasp or embrace stems and branches with great surety, and can thus obtain a firm hold.

It is, in the same Post Date: Mon, 18 Aug 2008 12:49:28 +0000
These hand-like feet are of the greatest importance to the animal. For after having obtained a firm footing by their help, it has its hands free for the most varied kinds of activities, the seizing of food, care of its young, etc. It is, in the same manner, enabled to pluck leaves or fruit from branches which would not bear its weight.

If one branch is not Post Date: Mon, 18 Aug 2008 12:31:05 +0000
(c) The arms are of great length, and by reason of the short legs, which, moreover, are never fully extended at the knee-joint, almost reach down to the feet. This great length of arm enables the creature to grasp branches at a great distance, to pluck fruit from the swaying summits of the trees and the ends of branches, and to lay hold of the boughs of neighbouring trees for the purpose of swinging itself on to them. If one branch is not found strong enough to bear its weight, the animal with its gigantic hands seizes hold of a whole cluster.

(d) Motion from one branch Post Date: Mon, 18 Aug 2008 12:18:40 +0000
The great length of the arm, further, enables the animal to walk down branches placed in a slanting direction. If its arms were not longer than those of man, it would, in consequence of the forward displacement of the centre of gravity, be exposed to the danger of falling (like a hare running downhill) . (d) Motion from one branch or one tree to another requires much greater strength than any movement on a level surface.

3 The movements Post Date: Mon, 18 Aug 2008 12:07:19 +0000
Hence the astonishing, superhuman strength of this animal. Inasmuch as the arms, which raise the body in mounting trees, perform the chief work, they vastly excel the legs in strength, whence also their muscles as well as those of the power- ful breast and broad shoulders are specially developed. 3 The movements of the animal on the surface of the ground are very awkward, in consequence of its hand-like feet and the inward direction of the soles of the feet.

Hence its usual and most Post Date: Mon, 18 Aug 2008 11:57:05 +0000
Only the exterior margin of the foot comes in contact with the ground. To walk with surety the animal is obliged to support itself on its hands, or really upon the knuckles of the bent fingers. Hence its usual and most natural progress is on "all fours.

) The animal, however, is but Post Date: Mon, 18 Aug 2008 11:40:53 +0000
" The Orang-Utan, in fact, is adapted to the one-sided existence of an arboreal animal. (To how many-sided an existence, on the other hand, is man adapted structurally ! Furnish proofs.) The animal, however, is but rarely obliged to descend to the ground, for the trees of the aboriginal forest provide it with its necessary food, while the rain which falls daily in its home, as well as the moisture con- tained in the food, supply it with the necessary amount of water.

1 Its dentition bears Post Date: Mon, 18 Aug 2008 11:25:04 +0000
The exuberant forests which form its home supply the animal with food in the greatest abundance. It consists of young leaves, juicy buds, and all sorts of fruits. 1 Its dentition bears the closest resemblance to that of man.

2 The neck is short Post Date: Mon, 18 Aug 2008 11:07:10 +0000
The four incisors, as well as the long dagger- shaped canines, by reason of their size, strength and sharpness, serve as an effectual weapon of defence .Powerful masticatory muscles enable it to bite with almost incredible strength. 2 The neck is short, the food being conveyed by the hands to the mouth.

We will relate Post Date: Mon, 18 Aug 2008 10:57:08 +0000
Compare in this respect animals eg, cattle, storks which pick up their food from the ground. On account of its great bodily strength, only the crocodile and the python venture to attack it. We will relate in the words of a naturalist, who has carefully studied its mode of life and habits, how the Orang- Utan manages, as a rule, to get even with these foes.
