plants, and buzzing sounds prove that the gloomy recesses of the woods are full of life and motion. Love-sighs are breathed through the fragrant perfumes of newly collapsed flowers, and all animated nature feels the influence of this moment of voluptuous tranquillity. Scattered gleams of light, reflected splendours of the departed sun, still float upon the woodland ridges; while, amidst a refreshing coolness, the mild moon arises in calm and silent grandeur, and diffusing her silver light over the dark forest, imparts to every object a new and softened aspect. Night comes;—nature sleeps, and the etheral canopy of heaven, arched out in awful immensity over the earth, sparkling with innumerable witnesses of far distant glories, infuses into the heart of man humility and confidence,—a divine gift after such a day of wonder and delight!—Mag. Nat. Hist. No. 24.

NOTES OF A READER.

THE BRITISH MUSEUM.

We are happy to learn that the celebrated Arundel MSS., which had been held for some time by the Royal Society, have recently been transferred to the British Museum; as well as a valuable addition of coins. In accordance with the suggestions made during the last Session of Parliament, the library of the Museum will henceforth be open to the public every day in the week, except Sundays.

During the past year 38,000 individuals visited the Museum, and very nearly 100,000, namely, 99,852 persons, from all parts of the kingdom, visited the Library for the purposes of study.

By the way, a livery-servant complained, in The Times of the 1st instant, that he had been refused admission to the Museum on an open and public day, in consequence of his wearing a livery, notwithstanding he saw "soldiers and sailors go in without the least objection." The Times remarks, "We believe livery-servants are not excluded from the sight at Windsor on an open day. We suspect that the regulation is not so much owing to any aristocratical notions on the part of the Directors of the Museum, as to that fastidious feeling which prevails in this country more than any other, and most of all among the lower ranks of the middle classes." The cause is reasonable enough; but we believe that livery-servants are not admitted at Windsor: the exclusion seems to be a caprice of Royalty, for servants are excluded from our palace-gardens, as Kensington. Surely this is unjust. If servants consent to wear liveries to gratify the vanity of their wealthy employers, it is hard to shut them out from common enjoyments on that account. This is in the true spirit of vassalage, of which the liveries are comparatively a harmless relic. In Paris we remember seeing a round-frocked peasant, apparently just from the plough, pacing the polished floor of the Louvre gallery with rough nailed shoes, and then resting on the velvet topped settees; and he was admitted gratis. Would such a person, tendering his shilling, be admitted to the Exhibition at Somerset House?

DOMESTIC CHEMISTRY.

This is an excellent little work by Mr. Brande: it is not avowedly so, although everyone familiar with his valuable Manual of Chemistry will soon identify the authorship. The present is only the first Part of this petite system, containing Attraction, Heat, Light, and Electricity. It is, as the author intended it to be, "less learned and elaborate than the usual systematic works, and at the same time more detailed, connected, and explicit than the 'Conversations' or 'Catechisms.'" It avoids "all prolixity of language and the use of less intelligible terms;" and, to speak plainly, the illustrative applications throughout the work are familiar as household words. Witness the following extract from the effects of Heat:

"In consequence of the lightness of heated air, it always rises to the upper parts of rooms and buildings, when it either escapes, or, becoming cooled and heavier, again descends. If, in cold weather, we sit under a skylight in a warm room, a current of cold air is felt descending upon the head, whilst warmer currents, rising from our bodies and coming into contact with the cold glass, impart to it their excess of heat. Being thus contracted in bulk, and rendered specifically heavier, they in their turn descend, and thus a perpetual motion is kept up in the mass of air. This effect is attended with much inconvenience to those who inhabit the room, and is in great measure prevented by the use of double windows, which prevent the rapid cooling and production of troublesome currents in the air of the apartment.

"We generally observe, when the door of a room is opened, that there are two distinct currents in the aperture; which may be rendered evident by holding in it the flame of a candle. At the upper part it is blown outwards, but inwards at the lower part; in the middle, scarcely any draught of air, one way or other, is perceptible.

"The art of ventilating rooms and buildings is in a great measure dependent upon the currents which we are enabled to produce in air by changes of temperature, and is a subject of considerable importance. As the heated air and effluvia of crowded rooms pass upwards, it is common to leave apertures in or near the ceiling for their escape. Were it not, indeed, for such contrivances, the upper parts of theatres and some other buildings would scarcely be endurable; but a mere aperture, though it allows the foul air to escape, in consequence of its specific lightness, is also apt to admit a counter-current of denser and cold air, which pours down into the room, and produces great inconvenience. This effect is prevented by heating, in any convenient way, the tube or flue through which the foul air escapes. A constantly ascending current is then established; and whenever cold air attempts to descend, the heat of the flue rarefies and drives it upwards. Thus the different ventilators may terminate in tubes connected with a chimney; or they may unite into a common trunk, which may pass over a furnace purposely for heating it.

"In some of our theatres, the gas chandelier is made a very effectual ventilator. It is suspended under a large funnel, which terminates in a cowl outside the roof; and the number of burners heat the air considerably, and cause its very rapid and constant ascent through the funnel, connected with which there may be other apertures in the ceiling of the building. But in these and most other cases, we may observe that the vents are not sufficiently capacious; and the foul air from the house, and from the gas-burners themselves, not being able readily to escape, diffuses itself over the upper part of the building, and renders the galleries hot and suffocating—all which is very easily prevented by the judicious adjustment of the size of the ventilating channels to the quantity of air which it is requisite should freely pass through them.

"The small tin ventilators, consisting of a rotating wheel, which we sometimes see in window-panes, are perfectly useless, though it is often imagined, in consequence of their apparent activity, that they must be very effectual; but the fact is, that a very trifling current of air suffices to put them in motion, and the apertures for its escape are so small as to produce no effectual change in the air of the apartment: they are also as often in motion by the ingress as by the egress of air.

"From what has been said, it will be obvious that our common fires and chimneys are most powerful ventilators, though their good services in this respect are often overlooked. As soon as the fire is lighted, a rapid ascending current of air is established in the chimney, and consequently there must be a constant ingress of fresh air to supply this demand, which generally enters the room through the crevices of
