In machines of human contrivance or art, there is no internal power, no principle in the machine itself, by which it can alter and accommodate itself to injury which it may suffer, or make up any injury which admits of repair. But in the natural machine, the animal body, this is most wonderfully provided for, by internal powers in the machine itself; many of which are not more certain and obvious in their effects, than they are above all human comprehension as to the manner and means of their operation. Thus, a wound heals up of itself; a broken bone is made firm again by a callus; a dead part is separated and thrown off; noxious juices are driven out by some of the emunctories; a redundancy is removed by some spontaneous bleeding; a bleeding naturally stops of itself; and the loss is in a measure compensated, by a contracting power in the vascular system, which accommodates the capacity of the vessels to the quantity contained. The stomach gives intimation when the supplies have been expended ; represents, with great exactness, the quantity and quality, of what is wanted in the present state of the machine ; and in proportion as she meets with neglect, rises in her demand, urges her petition in a louder tone, and with more forcible arguments For its protection, an animal body resists heat and cold in a very wonderful manner, and preserves an equal temperature in a burning and in a freezing atmosphere.

A farther excellence or superiority in the natural machine, if possible, still more astonishing, more beyond all human comprehension, than what we have been speaking of, is the distinction of sexes, and the effects of their united powers. Besides those internal powers of self-preservation in each individual, when two of them, of different sexes, unite, they are endued with powers of producing other animals or machines like themselves, which again are possessed of the same powers of producing others, and so of multiplying the species without end These are powers which mock all human invention or imitation. They are characteristics of the Divine Architect.- Thus far Paley.

Galen takes notice, that there are in the human body above 600 muscles, in each of which there are, at least, 10 several intentions, or due qualifications, to be observed; so that, about the muscles alone, no less than 6000 ends and aims are to be attended to! The bones are reckoned to be 284; and the distinct scopes or intentions of these are above 40 - in all about 12,000! and thus it is, in some proportion, with all the other parts, the skin, ligaments, vessels, and humours; but more especially with the several vessels, which do, in regard to their great variety, and multitude of their seve al intentions very much exceed the homogeneous parts.

---------------------------How august,

How complicate, bow wonderful, is man !

How passing wonder He who made him such!From different natures marvellously mixt;Though sully d and dishonour'd, still divine ! Young

"Come! all ye nations ! bless the Lord. To him your grateful homage pay: Your voices raise with one accord, Jehovah's praises to display.

From clay our complex frames he moulds,

And succours us in time of need : Like sheep when wandering from their folds,

He calls us back, and does us feed.

Then thro' the world let's shout his praise, Ten thousand million tongues should join,

To heav'n their thankful incense raise, And sound their Maker's love divine.

When rolling years have ceas'd their rounds,

Yet shall his goodness onward tend; For his great mercy has no bounds,

His truth and love shall never end!"

So curious is the texture or form of the human body in every part, and withal so "fearfully and wonderfully made," that even atheists, after having carefully surveyed the frame of it, and viewed the fitness and usefulness of its various parts, and their several intentions, have been struck with wonder, and their souls kindled into devotion towards the all-wise Maker of such a beautiful frame. And so convinced was Galen of the excellency of this piece of divine workmanship, that he is said to have allowed Epicurus a hundred years to find out a more commodious shape, situation, or texture, for any one part of the human body! Indeed, no understanding can be so low and mean, no heart so stupid and insensible, as not plainly to see, that nothing but Infinite Wisdom could, in so wonderful a manner, have fashioned the body of man, and inspired into it a being of superior faculties, whereby He teacheth us more than the beasts of the field, and maketh us wiser than the fowls of the heaven.

------------------Thrice happy men,

And sons of men, whom God hath thus advane'd;

Created in his image, here to dwell,

And worship him; and, in return to rule

O'er all his works. Milton.
