THAT amusing and useful melange, TIME'S TELESCOPE, for 1823, will be published, as usual, with the Almanacs, on the 19th of November. It consists of an explanation of Saints' Days and Holidays, with sketches of contemporary biography and comparative chronology; astronomical occurrences in every month, with remarks on indispensable astronomical instruments; and the naturalist's diary, explaining the various appearances in the animal and vegetable kingdoms. To which will be prefixed an Introduction on British insects; illustrated by a coloured plate. An ingenious instrument for ascertaining the longitude has been, it is said, invented by Mr. HARLEY, of the Chain Pier, at Trinity, which has been submitted to the inspection of some naval officers, who concur in opinion that it I will answer its intended purpose on land, or at sea in calm weather. A Mr. CLISSOLD, of London, has lately ascended to the summit of Mont Blanc. He set out from the Hotel de l'Union, on the 19th of August, with six guides. He passed the night at the Rocher Rouge, at an elevation of 2300 toises: here the thermometer fell to six degrees below Zero; and Hermitage wine froze in a corked bottle. He reached the summit of the mountain the next morning, about six o'clock. At half-past, the weather being very fine, the thermometer was at 17°. The traveller, with his guides, descended without any accident, and arrived at Chamouix the same evening. On the same day, two English ladies, Mrs. and Miss Campbell, crossed the Col de Giant, having ascended the Buel on the preceding day. An account of Columbia, with portraits of some of the leading men in that new State, is announced for publication. A Suspension Pier, at Brighton, is now erecting, under the direction of Capt. BROWN, the architect of the suspension iron bridge over the Tweed. The principle of the Pier is similar to that bridge. The plateau is suspended from chains, which hang from pier to pier, and the piers themselves, consisting of separated iron bars, are, of course, as such, exposed to a very slight action of the water. This pier will, doubtless, be a great convenience and advantage to the town of Brighton. But we hope care has been taken that the iron which comes in immediate contact with the water is wrought, not cast. If the latter material, the structure of this pier with such a decaying metal is most unwise. See our third volume, page 159; and JENNINGS's Family Cyclopædia, article BRIDGE. It is said that the celebrated French painter, DAVID, is preparing to exhibit one of his chef d'œuvres in London. It is a large picture, containing several hundred portraits of the most distinguished persons of the Revolution, and the court of Napoleon. M. DAVID now resides, we understand, at Brussels, where he pursues his studies with unabated ardour. Fifty lithographic prints, illustrative of a tour in France, Switzerland, and Italy, during the years 1819, 20, and 21, from original drawings taken in Italy, the Alps, and the Pyrenees, by MARIANNE COLSTON, in octavo, are preparing for publication. It is said that lithography is making rapid progress in Russia: a series of portraits of celebrated living characters has been commenced by a young artist of St. Petersburgh. A prospectus has appeared in the Bombay Courier, for publishing, by subscription, a Series of twenty Views in the Province of Kumaon, exhibiting the character of the foliage, style of building, mode of cultivating, &c. in that moutainous part of the world, taken by an officer employed in the detachment under the command of Col. Nicholls. The views will, in the first instance, be painted in oil colours, and then placed in the hands of an able artist, to be executed in the best style of coloured engravings; each plate to be not less than 24 by 16 inches.

No. XXIV. Recent Patents. To THOMAS GAUNTLETT, of Bath, Somersetshire, for certain Improvements on Vapour Baths, by which the Heat is better regulated, and the Baths rendered more portable.* THIS invention consists of a portable apparatus to be employed as a vapour bath, by means of which steam may be conducted to any particular limb of the patient, or to the whole surface of the body. Plate XIV. fig. 1, exhibits the apparatus as it would appear when in action. a, is a small boiler, calculated to hold about a gallon of water, to be placed upon the ordinary fire of the chamber; b, is a bent tube passing from the top of the boiler to a receiver, c, which is a vessel about the size of a small tea-pot; through this the steam passes, and is emitted from it to the bath. This vessel may con tain a small quantity of any volatile matter, which, being acted upon by the steam as it passes, will be discharged therewith in the form of vapour, through the spout and other passages of the receiver, the emission of which is regulated by the handle, d, to be turned by the patient or an assistant. e, is a standard intended to suspend a sort of bell-formed hood or marquee made of flannel or canvass, and distended with a hoop and cords. This hood, which is shown by dots, is intended to enclose the patient, who is to be seated upon a sort of camp stool within. But, as the top, and some other parts, of the hood, are furnished with openings, the head may be excluded from the action of the vapour, or any particular limb only may be introduced within the hood. Fig. 2 is a section of the cover of the boiler, a, shewing the construction of the safety valve and the pipe for emitting the steam. To this, another pipe, of any. desired length, may be coupled, as shewn at fig. 1. Fig. 3 is a section of the receiver, c, in which is seen the screw plug for regulating the emission of the vapour. The steam passing into this receiver, through the pipe, b, proceeds up the hollow screw plug, f, and escapes at the small holes into the space round the plug, and thence discharging itself, as shown by the radiant dots, fills the interior of the bell or hood; the width of the opening being regulated by the ascent or descent of the screw-plug, turned by the handle and universal joint, g. In order to direct a current of steam to the feet of the patient, which is sometimes particularly desirable, a channel is cut round the plug, in a winding direction, so as to be always opposite to the jet, h; by which means, a volume of steam is always discharged through the jet, whether the discharging space above be opened, wide or |
