our sight, contrary to that half lifeless dulness observed in summer, suggested the idea, that the whole body had availed themselves of this warm, moist evening, to migrate to their winter station. A single spark or so was to be seen some evenings after this, but no such large moving parties were discovered again. If we conclude, that the summer light of the glowworm is displayed as a signal taper, the appearance of this autumnal light can have no such object in view, nor can we rationally assign any use of it to the creature itself, unless, indeed, it serves as a point of union in these supposed migrations, like the leading call in the flight of night-moving birds. The activity and numbers of these insects, in the above-mentioned evening, enabled me to observe the frequent presence and disappearance of the light of an individual, which did not seem to be the result of will, but produced by situation. During the time the insect crawled along the ground, or upon the fine grass, the glow was hidden; but on its mounting any little blade, or sprig of moss, it turned round and presented the luminous caudal spot, which, on its falling or regaining its level, was hidden again.

A summary of the peculiarities of the year 1825, very appropriately concludes the volume, from which we may be tempted to make future extracts.

THE TALIPOT TREE,

The first of our Engravings is a species of palm, a native of Ceylon, and is one of the most magnificent wonders of the vegetable kingdom. The leaf is circular, terminating in the most beautiful rays, and folding up into plaits like a fan, which, in figure, it nearly resembles.

This leaf is used in the maritime provinces of Ceylon as a mark of distinction, each person being allowed to have a certain number of these leaves, folded up as fans, carried with him by his servants; and also in the Kandian country, in the shape of a round, flat umbrella on a long stick. The talipot leaves are likewise used by the common people to shelter themselves from the rain, one leaf affording sufficient shelter for seven or eight persons. It is also used in making tents.

In 1818, Sir Alexander Johnston gave to Sir Joseph Banks a very fine specimen of a tent made of their leaves, large enough to hold a party of ten persons at table.

All the books of importance in Pali and Cingalese, relative to the religion of Buddhoo, in Ceylon, are written on lamina of these leaves, with either a brass or an iron style. There are some of these books in Sir A. Johnston's collections, which are supposed to be from 500 to 600 years old, and which are still very perfect. In the museum of the Asiatic Society, there is a complete copy of the Pali book, called the Pansyapanas Iatakah, written on 1,172 laminae of the finest description of this sort of palm leaf. Large as the dimensions of the talipot leaf may appear, it is exceeded in size by the troolie of Surinam, which extends on the ground, and has frequently been known to attain the width of three feet, and the length of thirty.

Our Engraving is copied from the Gardener's Magazine, where it is reduced from the Transactions of the Asiatic Society.

THE DEATHWATCH MAGNIFIED.

Although the present may be a late hour to dissipate the faith placed in signs and tokens, we are persuaded that a more intimate knowledge of this insect will not prove uninteresting to our readers.³

The name death watch was evidently derived from the importance attached to the beatings of the insect, which, by superstitious people, were formerly supposed to prognosticate death to some one of the family in whose house it was heard. The natural size of the insect is about a quarter of an inch in length, of a dark brown colour, spotted, with transparent wings under the vagina, or sheath, a huge cap or helmet on the head, and two antennae, or feelers, from beneath the eyes.

It is chiefly in the advanced period of spring that these insects commence their noise; and which is the call or signal by which they are mutually attracted to each other, and may be considered as analogous to the call of birds. This noise does not arise from their voice, but from the insect beating on hard substances, with the shield or fore part of its head. The general number of successive distinct strokes is from 7 to 9 or 11. These are given in pretty quick succession, and are repeated at uncertain intervals; and in old houses, where the insects are numerous, they may be heard, if the weather be warm, almost every hour in the day. The noise exactly resembles that made by beating moderately hard with the finger on a table. Mr. Stackhouse carefully observed its manner of beating. He says, the insect raises itself upon its hinder legs, and with the body somewhat inclined, beats its head with great force and agility against the place on which it stands.

This insect, which is the real death-watch of the vulgar, must not be confounded with another minuter insect, which makes a ticking noise like a watch; but instead of beating at intervals, it continues its noise for a considerable time without intermission. This latter belongs to a very different tribe. It is usually found in old wood, decayed furniture, neglected books, &c.; and both the male and the female have the power of making this ticking noise, in order to attract each other. The Rev. Mr. Derham seems to have been the first naturalist who examined and described this species; and he says that during the month of July, in one particular summer, they scarcely ever ceased to beat either in day or night. The eggs are generally hatched about the beginning of March: many of them live through the winter; but during that time, to avoid the frost, they bury themselves deep in dust.

Mr. T. Carpenter (of whose paper in Gill's Repository we have already availed ourselves) tells us that these insects are excellent anatomists: in order to render them useful in making some delicate dissections for his microscope, Mr. Carpenter placed a few of the insects within a pill-box, with the heads of three dead flies. He found some time afterwards, that they had cleared the interior of some of the eyes completely from all the blood-vessels, leaving the lenses in the cornea beautifully transparent.

BIRDS' NESTS.

The structure of the nests of birds affords, perhaps, one of the most agreeable lessons in Natural History.

Among the most curious nests of our English birds may be named that of the Wren, the long-tailed Titmouse, the Thrush, the Goldfinch, the Chaffinch, the Magpie, and the House Sparrow; to these may also be added the Swallow's, the Martin's, the Wood Pigeon's, and the Wood-Pecker's. Of the nests of Rooks, it may be sufficient to observe, that they are often found to the number of six, or even more in a cluster. Crows' nests are always solitary; they are similar in structure to those of the rook.

Among the nests of Foreign birds, that of the Taylor Bird deserves especial mention; the bird itself is a diminutive one, being little more than three inches long; it is an inhabitant of India. The nest is sometimes constructed of two leaves, one of them dead; the latter is fixed to the living one as it hangs upon the tree, by sewing both together in the manner of a pouch or purse; it is open at the top, and the cavity is filled with fine down; and, being suspended from the branch, the birds are secure from the depredations of snakes and monkeys, to which they might otherwise fall a prey.

In Dr. Latham's collection is a specimen of the taylor bird's nest, composed of a single large leaf, of a fibrous rough, texture, about
