The eyes of insects have afforded much room for microscopic observation. The greater part of insects have not moveable eyes, which they can cover with eyelids at pleasure. In these, the eyes are im. moveable, and, as they are deprived of a covering to defend them from injuries, nature has supplied this deficiency, by forming them of a kind of corneous substance, proper for resisting the shocks to which they might be exposed. But it is not in this, that the great singularity of the eyes of insects con. sists. By the microscope, we find these eyes are themselves divided into a prodigious multitude of others much smaller. Some flies are said to have see veral thousand eyes. In all the different species they are disposed in a different manner. The dragon fly, besides the two hemispherical excrescences on the sides, which are visible to the naked eye, has between these two other eminences, the upper and convex surface of which is furnished with a multihide of eyes. The same insect was three also in front, in the form of an obtuse and rounded cone. It is an agreeable spectacle, says Leeuwenhoek, to examine this multitude of eyes in insects; for, if the observer be in a proper position, the surrounding objects appear painted on these spherical eminences; and, by means of the microscope, they are seen multiplied, almost as many times as there are eyes, and in such a distinct manner, as can never be attained by art

DESCRIPTION OF FRUIT TREES.
[Continued from p. 140.] NECTARINE TREE ramygdalus persica).-Botanists allow this to be only a variety of the peach tree. It certainly is not easy for a common eye to distinguish between the two trees when they are not in a state of fructification, nor will the differences then observable authorize us to pronounce them specifically separate. The nectarine is generally a lower tree than the peach; the trunk and branches are, however, larger, besides being covered with a lighter bark. The twigs are tenderer and inclining to red. The flowers are smaller and of a darker red colour. These differences, bowever, are often trifling, and by no means constant. The grand distinction is certainly in the fruit, which is smaller and rounder, with a firmer pulp and a smoother skin. It derives its classical name from the rich, racy, and nectareous flavour of its juice, which, in its highest perfection, renders it the most delicious of all European fruits, and, perhaps, surpasses that of the boasted products of botter climes. The best sorts of nectarine are those called the Newington and the Roman. The first is a fine large fruit, of a beautiful red colour towards the sun, and of a bright yellow towards the wall; the juice is very rich; the pulp adheres closely to the stone, where it is very red; and the fruit ripens at the end of August or beginning of September. The Roman red nectarine has a deep red or purple colour towards the sun, but next the wall has a yellowish cast; the pulp is firm, adheres closely to the stone, and ripens in September. It requires a very close attention to distinguish the trees which bear the different varieties of this exquisite fruit. The same sort of trees, planted in different soils and situations, often alter their fruit so much as to deceive the best judges. See
PEACH TREE (amygdalus persica). This, in its natural state, is a small tree, with spreading branches. It grows rapidly, but is not a long liver. There are many varieties of the fruit for which the peach tree is principally cultivated; but the trees themselves are valuable in another respect, for there are few that are more ornamental for plantations, shrubberies, and wilderness quarters, especially when placed in view of the mansion house, and in sheltered situations, where they will display their beautiful blossoms about the beginning of April, when flowers, especially upon trees, are peculiarly valuable. The variety with double flowers is the most elegant of all the ornamental trees; at least, with the exception of the almond tree, it is the most beautiful flowering tree that will live in the open air of our variable climate. Its blossoms appear about three weeks later than those of the common peach, and are generally followed by some fruit, which it must be confessed is not of any value, except where the trees have been trained against sunny walls.
The most valuable kinds of peach trees are the following :-The early purple peach, the fruit of which is large, round, and externally of a fine red colour; the flesh is white, but very red at the stone. It is particularly esteemed for being full of a rich vinous-flavoured juice. The next sort we shall notice is the large or French mignon (yrosse mignonne), the fruit of which is rather egg-shaped, only often swelling on one side. It has a fine external colour, a sugary juice, and a very small stone. As it ripens in the middle of August, and separates from the stone, it is allowed to be one of the finest peaches. The best method of treating this tree is to bud it into some old healthy apricot, planted in a south east aspect, and to cut away the apricot when the buds have taken and produced shoots. The belle chevreuse is an excellent bearer; the fruit is red, the flesh white, but red at the stone, from which it separates: it is very full of a rich sugary juice, and ripens at the end of August. The Chancellor has a white melting flesh, which separates from the stone, where it is of a fine red colour; the skin is thin and the juice very rich: it ripens about the end of August, and should be budded on an apricot like the mignon, as it thrives better under that treatment than upon common stocks.
These are the sorts most worthy of cultivation; though in very warm situations the Catharine peach should be introduced, as it is an excellent fruit in hot summers.
An eminent gardener describes a good peach as follows: the flesh should be firm, the skin thin, next the sun of a bright red colour, and of a yellowish cast next the wall; the pulp should be very thick, yellowish, and full of high-flavoured juice. This fruit
