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.

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 six inches long independent of the stalk, five inches and a half in breadth, and ending in a point. The sides of this leaf are drawn together so as to meet within three-quarters of an inch; within is the nest, about four inches deep and two broad, opening at the top; the bottom of the leaf is drawn upwards, to assist in the support of it. The interior nest is composed of white down, with here and there a feather and a small portion of white down intermixed.
Another nest of this bird has also been described as composed of several leaves, like those of some kind of hazel sewed together; the inner nest formed of dry bents, fibres, and hairs, suspended from a tree. It is, therefore, probable that this bird, as well as some others, varies the structure of its nest as occasion and the materials may require. These singular works are performed by the bird's using his bill instead of a needle, and vegetable fibres for thread.
The Rufous Bee-eater, or Merops Rufus, constructs also a very singular nest. This bird is a native of Buenos Ayres; the nest is built generally on the naked great branch of a tree, sometimes on the windows of houses, a fence, or a projecting beam of a high house or other building; it is composed of earth, in the form of a baker's oven, and is often built in the short space of two days, both birds being engaged in its construction; it is six inches in diameter, and one thick; a division is within, beginning at the entrance, and carried circularly, so that the eggs are deposited in the inner chamber, on a bed of grass. The swallow and other birds often attempt to obtain possession of this nest, but are generally repulsed by the owners.
Many of the Orioles' nests are also deserving notice. The black and yellow Oriole, inhabiting South America, has a pendent nest, shaped like an alembic; it is affixed to the extreme branches of trees; sometimes, it is said, so many as four hundred nests are found hanging on the same tree.
The Philippine and Pensile Grosbeak make also very curious nests.
In concluding this account of the nests of birds, I may notice here the nest of the Hirundo esculenta, or Esculent Swallow, an inhabitant of China and the Islands of the Indian Ocean. The nest consists of a gelatinous substance, in shape resembling an apple cut down the middle. The nests are found in great numbers together, and are by the luxurious Asiatics made into broths, and otherwise cooked, and are esteemed one of the greatest dainties of the table; they are also occasionally used for glue.—Jennings's Ornithologia.

METROPOLITAN IMPROVEMENTS
The year 1825 will ever be memorable in the annals of the metropolis; for more novel improvements, changes, and events occurred in that one year than during any other corresponding period. Schemes for the formation of new Companies—the vast speculations arising out of them, tending to the aggrandizement of a few persons, and to the ruin of others, with the utilities of some, and the futilities and impositions of many,—may also be said to belong to this year.
Let us, however, take a brief review of the real improvements and useful novelties that have been progressing, or have commenced in London since that singular and eventful era. Commencing at the court, or west end, we will take an imaginary tour to the east, adverting to such new buildings as are calculated to arrest the attention of the stranger in our progress. Without remarking on the general improvements of the age, we shall find enough to engross our attention in the particular objects before us. The most noted, or conspicuous of these are:—1. The New Palace, with the adjoining Park and Gardens. 2. A Terrace, Street, and Public Buildings on the site of Carlton House. 3. Belgrave Square, and the adjoining Squares and Streets.
