polished steel inclining a little to greest, and its abdomen is red like polished copper.

The body of most caterpillars presents a compound of different colours often mingled with so much art that the most skilful workman could not imitate them in his most gaudy stuffs of silk, and convinces us that Solomon in all his glory was not arrayed like one of these- Some have the body marked with dots or points of different colours, or with spots larger than (the points, of unequal bigness, and of irregular shape; or ladW, with points and spots at the fame time, variously but beautifully disposed. The bodies of other caterpillars are adorned with lines, and bands of different colours, and of different figures: some are longitudinal, others transverse; sometimes continuous, at other times interrupted, as if they had been cut in different places. There are likewise some that have lines longituJinal and transverse at the same time. In some caterpillars the sots take the figure of lozenges and rhomboids; in others that of bands, a little broader than the lines, which are either longitudinal or transverse. There is often an agreeable intermixture of all these marks at the fame time. Som~ are adorned with lines and points, others with points and bands, and a third with points, lines, and bands, all at once.

The little tubercles of the size of a grain of millet, cr of poppy feed, which are seen on the body of many caterpillars, are no small ornament to them. These small elevations are so smooth ani so polished, that when we look at the animal possessed of them, we would think it studded with jewels. The resemblance is the more striking, as these tubercles are of different colours. Some have the whiteness ot the diamond, others the redness of the ruby :, some ar?

A a yellow yellow like a chrysolite, others blue like an amethyst, and so forth.

Not less magnisicence is displayed in jhe disserent colours which adorn the wings of insects. In the sirst place, we sind these points and spots of every difserent colours. Some of these last are round like the pupil of the eye, and like it, surrounded with a circle. For this reason, naturalists have given them the name of eyes; but, two reasons determine me to preser the name given them by Friseh, to wit, mirror points. First, that they may not be consounded with the real eyes: and secondly, because these spots are not always surrounded with a circular margin like eyes, but this margin is often of a difserent sigure, and varies as much as the shape of a mirror may be arbitrarily varied. Sometimes there is only one of these on the wings of insects, sometimes there rrre many. Some have lines on their wings, either straight or waved; others have broad bands; some have triangular marks at the extremities of the wings, or other ornaments of that kind. It would be impossible to describe the whole of them, considering their vast variety; but in general, they are disposed with as much regularity, as if they were she work of a careful painter. The upper and under surfaces of the wings are not always adorned with the fame colours. It would appear, that some butterflies were sensible of this, by the manner in which they hold their wings while at rest. They keep them standing erect, as if to invite spectators to admire their beauty. It must be remarked, likewise with regard to those insects which have four wings, that the colours of the upper difser from thole of the under wings. Nor mqst I omit to mention, that these colours are most vivid in the wings of living Insects, and that they sometimes fade when the aninial dies. It is also to be observed, that insects which have farinaceous, wings, if they are to be kept, must nor, when caught, be handled too roughly; for, as they owe their colours to that powder, or rather to those feathers, which, from their smallness, escape our senses; they lose all their brilliance, when/ these are either destroyed or deranged.

The membranous wirtgs of insects have also their particular beauties. Some present to the view, an assemblage of colours like those of the rain-bow, or like those formed by the rays of the fun, in passing through a prism. They vary according to the differs ent refraction of the rays, so that, what at first appeared red, becomes afterwards blue or green, nearly like the colours on a pigeon's neck, which change zccording to their different position with regard to the Sun. There are often between the nerves of the wings of some insects, small spots which appear like so many ornaments wrought on fine gauze.

We have said that there are insects whose wings *" are covered with a kind of cafe to protect them from accidents. These cases have likewise their particular beauties. In some insects they are of a uniform colour, as yellow, red of various shades, green, blue, violet, brown and black. In some these colours are dull, in others bright and shining like a transparent varnilh. Of this last kind are those insects of the Buprestis and Curculio kind, whose elytra seem adorned with emeralds and gold. The elytra of other insects are variegated with different colours. Those of the Silpha Vespillo are painted alternately with transverse and waved bands of black and reddish yellow. The ground colour of thole of the Coecinella conglobata is yellow, but it is adorned with square black soots like those on a chess board. The Silpha 4-punctata has two squaie spots on each e1) tron. The Leptura arcuata is of a deep black cc-

lour with yellow spots on the upper, and hook-shaped bands oi the fame colour on the under part. The Leptura scalaris has on its elytra indented ornaments which at the place where the elytra meet pretty much resemble Spanish point. I once found a beetle, or^a woodbine growing out of a rock, whose elytra were marked with small bars, some green, some deep red, like polished copper, and others of a deep blue, like burnished steel.

The beauty of different flowers, the diversity remarkable in the colours of shells, the splendor of those in the tail of a peacock, no doubt, excite our admiration; but that they are not ihe only coloured bodies capable of producing that effect on our minds, we have only to cast our eyes on some insects to be coi vinced. Though these small animals were of no use in the world we would still be indebted to the Creator, for having given them existence. The mere si>;ht of them gives us pleasure; the mind feels a sensible gratification, in contemplating so many beauties in so small a space. This is not all. If we are wife, we shall rife from those beautiful objects to their Maker. What must be the riches of a Being, who hath lavished so many treasures on the vilest of infects! The beauty of these creatures, which calls forth our admiration and delight, being so much inferior ro that of the Creator, would h not be blindness, not io acknowledge, to admire, and to love him, who is the source of whatever is amiable and and worthy of admiration in the wotks of his hands? If we would proportion the degree of our affections to the excellence of their object, we nught to love God, with our whole heart. What folly is it, not to pride ourselves on the beauty of the stuffs with which ve are clothed! Velvet and siik, which are the most preoous of these, whence come they I They are the excrement of a vile insect. And our richest garb* it it equal in beauty to that with which many of these small animals are decked?. With justice, we may fay, that Solomon in all his gloiy, was not arrayed like one of these*

CHAP. I. Of The Uses Of Insects With Respect To Man.

Insects, considered in a supersicial manner, with, out entring into a particular examination of their qualities, appear to be creatures of little or no use. This is an error, which after having read this Chapter y people will not easily fall into. I confess it would be rash to decide positively concerning the particular use which the wisdom ot God had in view in the" creation of each individual specie?. We may however conclude from the use they are of, from the benesits we derive from them, that God among others, had that particular use in view when he created them Every event in nature proclaims that whatever happens is directed by a Being insinitely wise. From this principle it follows that God hath determined the uses of ani
