One principle of gravitation causes a stone to drop towards the earth, and the moon to wheel round it. One law of attraction carries all the different planets about the sun. This philosophers demonstrate. There are also other points of agreement amongst them, which may be considered as marks of the identity of their origin, and of their intelligent Author. In all are found the conveniency and stability derived from gravitation. They all experience vicissitudes of days and nights, and changes of season. They all, at least Jupiter, Mars, and Venus, have the same advantages from their atmosphere as we have. In all the planets, the axes of rotation are permanent. Nothing is more probable, than that the same attracting influence, acting accord

ing to the same rule, reaches to the fixed stars; but, if this

be only probable, another thing is certain, viz. that the same element of light does. The light from a fixed star affects our eyes in the same manner, is refracted and reflected according to the same laws, as the light of a candle The velocity of the light of the fixed stars is also the same as the velocity of the light of the sun, reflected from the satellites of Jupiter. The heat of the sun, in kind, differs nothing from the heat of a coal fire. In our own globe, the case is clearer. New countries are continually discovered, but the old laws of nature are always found in them: new plants perhaps, or animals, but always in company with plants and animals which we already know: and always possessing many of the same general properties. We never get among such original, or totally different, modes of existence, as to indicate, that we are come into the province of a different Creator, or under the direction of a different will. In truth, the same order of things attends us wherever we go. The elements act upon one another, electricity operates, the tides rise and fall, the magnetic needle elects its position in one region of the earth and sea as well as in another. One atmosphere invests all parts of the globe, and connects all; one sun illuminates; one moon exerts its specific attraction upon all parts. If there be a variety in natural effects, as, e.g. in the tides of different seas, that very variety is the result of the same cause, acting under different circumstances. In many cases this is proved; in all, is probable. The inspection and comparison of living forms, add to this argument examples without number. Of all large terrestrial animals, the structure is very much alike; their senses nearly the same; their natural functions and passions hearly the same; their viscera nearly the same, both in substance, shape, and office: digestion, nutrition, cir culation, secretion, go on, in a similar manner, in all. The great circulating fluid is the same; for, I think, no differ ence has been discovered in the properties of blood, from whatever animal it be drawn. The experiment of transfu sion proves, that the blood of one animal will serve for another. The skeletons also of the larger terrestrial animals, show particular varieties, but still under a great general affinity The resemblance is somewhat less, yet sufficiently evident, between quadrupeds and birds. They are all alike in five respects, for one in which they differ.

In fish, which belong to another department, as it were, of nature, the points of comparison become fewer. But we never lose sight of our analogy, e. g. we still meet with a stomach, a liver, a spine; with bile and blood; with teeth; with eyes,—(which eyes are only slightly varied from our own, and which variation, in truth, demonstrates, not an interruption, but a continuance of the same exquisite plan; for it is the adaptation of the organ to the element, viz. to the different refraction of light passing into the eye out of a denser medium.) The provinces, also, themselves of water and earth, are connected by the species of animals which inhabit both; and also by a large tribe of aquatic animals, which closely resemble the terrestrial in their internal structure; I mean the cetaceous tribe, which have hot blood, respiring lungs, bowels, and other essential parts, like those of land animals. This similitude, surely, bespeaks the same creation and the same Creator.

Insects and shell-fish appear to me to differ from other classes of animals the most widely of any. Yet even here, beside many points of particular resemblance, there exists a general relation of a peculiar kind. It is the relation of inversion; the law of contrariety: namely, that whereas, in other animals, the bones, to which the muscles are attached, lie within the body; in insects and shell-fish they lie on the outside of it....The shell of a lobster performs to the animal the office of a bone, by furnishing to the tendons that fixed basis or immovable fulcrum, without which, mechanically, they could not act. The crust of an insect is its shell, and answers the like purpose. The shell also of an oyster stands in the place of a bone; the bases of the muscles being fixed to it, in the same manner as, in other animals, they are fixed to the bones. All which (under wonderful varieties, indeed, and adaptations of form) contesses an imitation, a remembrance, a carrying on, of the same plan

The observations here made are equally applicable to plants; but, I think, unnecessary to be pursued.

It is a very striking circumstance, and alone sufficient to prove all which we contend for, that in this part likewise of organized nature, we perceive a continuation of the seaual system.

Certain however it is, that the whole argument for the divine unity, goes no farther than to a unity of counsel. • It may likewise be acknowledged, that no arguments which we are in possession of, exclude the ministry of subordinate agents. If such there be, they act under a presiding, a controlling will; because they act according to certain general restrictions, by certain common rules, and, as it should seem, upon a general plan: but still such agents, and different ranks, and classes, and degrees of them, may be employed.

THE proof of the divine goodness rests upon two propositions, each, as we contend, capable of being made out by observations drawn from the appearances of nature. The first is, “that in a vast plurality of instances in which contrivance is perceived, the design of the contrivance is beneficial. -- --The second, “that the Deity has superadded pleasure to animal-sensations, beyond what was necessary for any other purpose, or when the purpose, so far as it was necessary, might have been effected by the operation of pain.” First, “in a vast plurality of instances in which contrivance is perceived, the design of the contrivance is benecial.” No productions of nature display contrivance so manifestly as the parts of animals; and the parts of animals have all of them, I believe, a real, and, with very few exceptions, all of them a known and intelligible, subserviency to the use of the animal. Now, when the multitude of animals is considered, the number of parts in each, their figure and fitness, the faculties depending upon them, the variety of species, the complexity of structure, the success, in sc many cases, and felicity of the result, we can never reflect, without the profoundest adoration, upon the character of

that Being from whom all these things have proceeded: we
cannot help acknowledging, what an exertion of benevo-
lence creation was; of a benevolence how minute in its
care, how vast in its comprehension! *
When we appeal to the parts and faculties of animals,
and to the limbs and senses of animals in particular, we
state, I conceive, the proper medium of proof for the con-
clusion which we wish to establish. I will not say that
the insensible parts of nature are made solely for the sensi-
tive parts; but this I say, that, when we consider the be-
nevolence of the Deity, we can only consider it in relation
to sensitive being. Without this reference, or referred to
anything else, the attribute has no object; the term has
no meaning. Dead matter is nothing. The parts, there-
fore, especially the limbs and senses of animals, although
they constitute, in mass and quantity, a small portion of the
material creation, yet, since they alone are instruments of
perception, they compose what may be called the whole of
visible nature, estimated with a view to the disposition of
its Author. Consequently, it is in these that we are to seek
his character. It is by these that we are to prove, that the
world was made with a benevolent design.
Nor is the design abortive It is a hap world after all.
The air, the earth, the water, teem with delighted exist-
ence. In a spring noon, or a summer evening, on which-
ever side I turn my eyes, myriads of happy beings crowd
upon my view. “The insect youth are on the wing.”
Swarms of new-born flies are trying their pinions in the
air. Their sportive motions, their wanton mazes, their
gratuitous activity, their continual change of place without
use or purpose, testify their joy, and the exultation which
they feel in their lately discovered faculties. A bee amongst

the flowers in spring, is one of the most cheerful objects that .

can be looked upon. Its life appears to be all enjoyment; so busy, and so pleased: yet it is only a specimen of insect life, with which, by reason of the animal being half domesticated, we happen to be better acquainted than we are with that of others. The whole winged insect tribe, it is probable, are equally intent upon their proper employments, and, under every variety of constitution, gratified, and perhaps equally gratified, by the offices which the Author of their nature has assigned to them. But the atmosphere is not the only scene of enjoyinent for the insect race. Plants are covered with aphides, greedily sucking their juices, and constantly, as it should seem, in the act of sucking.

cannot be doubted but that this is a state of gratification What else should fix them so close to the operation, and -* so long? Other species are running about, with an alacrily in their motions, which carries with it every mark of pleasure. Large patches of ground are sometimes half covered with these brisk and sprightly natures. If we look to what the waters produce, shoals of the fry of fish frequent the margins of rivers, of lakes, and of the sea itself. These are so happy, that they know not what to do with themselves Their attitudes, their vivacity, their leaps out of the water, their frolics in it, (which I have noticed a thousand times with equal attention and amusement,) all conduce to show their excess of spirits, and are simply the effects of that excess. Walking by the seaside, in a calm evening, upon a sandy shore, and with an ebbing tide, I have frequently remarked the appearance of a dark cloud, or rather, very thick mist, hanging over the edge of the water, to the height, perhaps, of half a yard, and of the breadth of two or three yards, stretching along the coast as far as the eye could reach, and always retiring with the water. When this cloud came to be examined, it proved to be nothing else than so much space, filled with young shrimps, in the act of bounding into the air from the shallow margin of the water, or from the wet sand. If any motion of a mute ani"mal could express delight, it was this: if they had meant to make signs of their happiness, they could not have done it more intelligibly. Suppose then, what I have no doubt of, each individual of this number to be in a state of positive enjoyment; what a sum, collectively, of gratification and pleasure have we here before our view! The young of all animals appear to me to receive pleasure simply from the exercise of their limbs and bodily saculties, without reference to any end to be attained, or any use to be answered by the exertion. A child, without knowing anything of the use of language, is in a high degree delighted with being able to speak. Its incessants repetition of the few articulate sounds, or perhaps of the single word which it has learned to pronounce, proves this point clearly. Nor is it less pleased with its first successful endeavours to walk, or rather to run, (which precedes walking,) although entirely ignorant of the importance of the attainment to its future life, and even without applying it to any present purpose. A child is delighted with speaking, without having anything to say; and with walking, without knowing where to go. And, prior to both these, I am disposed to believe, that the waking hours of
