'had commanded.' Gen. vll. 11 -16- Infects therefore are not excepted from this general law. God hath made them to preserve their species by the intercourse of male with female; God hath endowed them with the proper organs for this purpose. God in short, hath blessed them like the other animals that they may multiply and replenish the earth. The effect of this benediction has subsisted for thousands of years without our being able1 to observe any alteration. What exalted idea ought not this to give us of the power and wisdom of him who hath established so permanent a regulation, and which has not suffered any interruption in the course of so long a succession of ages! .

'j'here is hardly any substance in nature which" does not afford a lodging place for insects. Of this Imean in the present Chapter to convince my readers.

Water is not an element proper for every fort of animal. Those who are not furnished with organs that fit them to inhabit it, perish in a short time,, when by any accident they fail into it. If it had not pleased God to form creatures capable of sustaining life in that element it would have been desertj but besides fishes ot every kind, he has created a great number of insects to inhabit the waters. As among those there are many which cannot live "but in salt water, so among these there are many which would perish in fresh waters. On the other hand, the fairness of the sea would kill many which cannot live but in fresh waters. Hot springs, in which a person cannot-hold his hand without being burnt, would seem to be a very improper abode for living beings ; and yet there are insects found, which live and thrive in thern,N and die when taken elsewhere. It is well known that these little creatures very much dread the cold, which generally benumbs them; would one then expect to find some in snow ? We know likewise that offensive smells arid, oily substances are injurious to them, yet some inhabit the water of dunghills, in which both these inconveniences are united. There are even Naturalists who pretend to have discovered some in fire j but I doubt the truth of their observations. Fire is an element which destroys and dissolves every thing! how then mould an insect resist its action ? It is very certain that they are found both in natural and artificial liquors. The curious have perceived them in • the bleedings of the vine newly drawn, in wine, in vinegar, and in infusions of every kind; a phenomenon the more surprising as the greatest part of insects have an aversion at every thing which is aeid or pungent, as some of these liquors are. Lastly there are amphibious insects as well as other animals. Many species live equally well in water or in air. They delight to be in the vicinity of water, on the surface of which they are seen flying, and serve for food to the animals of both elements.

The earth, both in its surface and below it, is not less peopled with numbers of infects than the waters. Some have no other domicile than below the surface pf the earth ; others may retire thither for | rotection against the rigours of winter; hence many derive the names which distinguish them from other ij?ecie,s. For example, we call thoie fties, larvae and soils 2 ders ders which live in the earth, land infects, to distinguish them from others of the fame kind that live elsewhere. It , is not indifferent to them what foil they -make use of} they are' seen seeking with anxiety for that which is fittest for their purpose, and there they fix. Others make vaults underground, through which they creep ?nd walk; others content themselves with a hole which they fabricate with wonderful art, and in which they nestle. Grasshoppers delight in a dry foil, and crickets love to dwell in walls constructed of mud. parth newly dug, swarms with infects, some of which feed pri the roots of plants, and others on the earth itself. Some live only in sandy soils, others only in that formed of rotten wood. Some lodge in the fet and putrid earth of dunghills? pnd find what is necessary to Use in a place which would kill pthpr infects. In this class I rank flies, some beetles, and the larvae of dunghills. Others seek th,eir food in the excrement of animals, and are found in it both before and after its exclusion. Some put themselves under stones which ferve^ them as a canopy; while others gnaw them, however hard, till they have excavated a hole in which they can. lodge. Lastly they are found in vast numbers on, the surface of the earth; such are the land pulices, grasshoppers, millepieds, Sjc. *

There is hardly a plant which doe? not nouristj some insect. Some people eyen affirm that each has a species of insect peculiar to itself; but it also often happens that the fame plant serves as'a residence to. many species of these little animals. Some creep in the grafs, or construct in it dwellings for themselves. Others lodge about the roots of plants, or fabricate small apartments near them j some lastly harbour in {he bulbs pf flowers.

The gras§ is like a large carpet on which many

r. - species species of insects are found. The larvæ of all forts pf infects are found on the wormwood, the pabbage, the borrage, the nettle, on fennei, flax ground ivy. motherwort, chervil, mint, cress, orach, buglofs, melilot, anise, plaintain, and spurge. Some lodge between the two membranes of the leaf; the under one serves them for a bed, the upper for a covering. Others which have derived their name from the circumstance, roll up the leaves like a cylinder; attach the different folds with a thread which they draw from themselves, and shut themselves up in it. Laflly some are found fixed o;i flowers. The anemone, the flowers of the wild cress, of hyacinths, July flow* ers, larkspurs, roses, violets <5yC. serve as a habitation for many species.

Nothing is secure against the voracity of these importunate guests ; they spare no sort of fruit whether dry or green. They are found not only on the leaves, the ears and stems of corn, but also in the dried grain; such as pease, beans, oats, &c. and, in the bread made of these.

They mount up on shrubs and lodge there. They delight in the hawthorn, the elder, the goose-berry, the quince, the vine &c. Some keep themselves on the outside of the leaves, while others penetrate within, between the two membranes, attach themselves to the flowers or insinuate themselves into the wood itself, and there cause small excrescences.

The larger trees are worlds peopled with various species ofinsccts, and there islhardly a partofthem which these little animals do not attack. Some that have acquired the name of ambitions:, do not confine themselves to a single tree, but go from one to another, seemingly desirous of tasting all. Others are more constant, and attach themselves to the root, the bark

QV or wood of the tree, and keep fixed there. The taste of these last varies. Some prefer green to rotr ten wood, others esteem dry wood betore what is, moist, and are better pleased with those places in vhich corruption has begun, than with those that are found. Some live on the leaves of trees, as the lime, the mulberry, the alder, the willow &c. Some insinuate themselves within the parenchyma of those leaves, and live between the two membranes which cover them, while oihers are the cause of an excrescence in which they lodge. These are of many species; and it is easy to know them by the different form of the excrescence they live in, Some make it of a round form either on the upper surface of the leaf, as those on the beech, or on the under surface like thole of the oak; some on the margins as those of the willow, others give it the figure of a* cone like those on the lime. The flowers of trees, have likewise their inhabitants. Insects are found on thole of the cherry, the apple, the plumb, the bazle, &c. nay, they penetrate the fruit, and spoil our apples, pears, figs, cherries, nuts.&c.

But it is not plants alone that insects chuse for their abede, they likewise effect a lodgement in animals and even in other insects. It is well known that the ichneumon flies lay their eggs in the bodies of caterpillars and spiders where they are afterwards hatched. Before this fact was perfectly ascertained it was easy to fall into error, and to believe that one, species of insects sometimes produced a species different, from itself. Can we be surprised then that some naturalists should advance this paradox? Some are found attaching themselves to the outside of another insect without penetrating furT ther; thus we find a fort of lice on aquatic insects, on bees, butterflies and beetles. Serpents likewise nourish mapy insects. I have not yet been able tp
