A stove in the House of Lords was selected as a proper place for the incremation of anots the compressed air to fill the belt, which increases his levity and assists his ascent. The armor used by Mr. Dean in 1834, when he descended to the wreck of the Royal George (sunk off Spithead, August 28, 1782), was composed of india-rubber, mae of the art,—to borrow the conventional phrase, which is as good as any other. 1.

Cata-di-op′tric light. A mode of illumination for lighthouses in which reflection and refraction are unitedly employed. Suggested by Allan Stevenson in 1834. From their subjecting the whole of the available light to the corrective action of the instrument, they have been called holophotal lights. Catadioptric light

is by reflectors. Refraction instead of reflection. Lenses were used in the South Foreland light in 1752, and in the Portland light, England, in 1789. The system fell into disfavor, owing to certain mechanical difficulties in the construction and arrangement of the lenses. It was revived and improved by Fresnel about 1810, and has been generally adopted throughout France and Holland, and partially in England. It is considered superior to the catoptric, and was readopted in England in 1834, being placed in the Lundy Island Lighthouse, Devonshire, England. The Fresnel dioptric lamp consists of a mechanical, four-wicked oil-lamp, placed in the center of an octagonal glass prism; the center part of each of the sides being formed of a plano-convex lens of about 15 inches diameter, which is surrounded by a series of glass rings of a spherical triangular form, so as to produce the same effect upon the rays as is produced by the central lens.

he observatory; this, by means of right and left hand deflection-needles, was caused to print dots on a continuous slip of paper, moved by clock-work. While making experiments in connection with this work, Steinheil made the important discovery that the earth might be used as a part of the circuit, thus enabling him to dispense with one half the length of wire which was thought requisite. The attention of Wheatstone, in England, appears to have been drawn to the subject of telegraphy in 1834. Morse's first idea was to employ chemical agencies for recording the signals, but he subsequently abandoned this for an apparatus which simply marked on strips of paper the dots and dashes composing his alphabet. The paper itself is now generally dispensed with, at least in this country, and the signals read by sound, — a practice which conduces to accuracy in transmission, as the ear is found less liable to mistake the duration and succession of sounds than the eye to read a series of

made of gold, which they call in chymistry Aurum Fulminans, a grain, I think he said, of it, put into a silver spoon and fired, will give a blow like a musquett, and strike a hole through the silver spoon. — Pepys, 1663. A fulminating powder which explodes when heated to 360° may be made of niter, 3 parts; dry carbonate of potash, 2 parts; sulphur, 1 part.

To destroy insects or vermin in their holes, or upon clothing, trees, or plants. 2. To destroy infection or miasma in buildings, ships, clothing, or feathers. 3. To diffuse a fragrant or invigorating perfume through an apartment or ward. 4. To suffuse the lungs with a soothing or healing vapor.

a pre-eminence in England for general purposes; others are used for grinding, while many varieties are employed as plane surfaces for whetstones. Other qualities are used for hones. A German variety is famous for this purpose. The very finest qualities, composed of an almost impalpable agglutinated powder, are used as oil-stones. Such are the Water of Ayr, and Blue stones, and the Turkey oil-stone. The old Royal exchange of London was pavel with this stone, and when it was burned, about 1834, the pavement yielded a handsome amount towards the re-erection. Grinding-wheels. The Nova Scotia and Berea, Ohio, grindstones are largely employed in this country; these may be obtained of very large size and uniform quality. The Washita, Arkansas, stone is of the very finest quality, being sharp and clean, and is made into a great variety of forms; grindstones, whetstones, hones, and slips of various sizes and forms. In dressing rough grindstones, the process of hacking is employ

for sulphide of antimony, and the match ignited on any rough surface. The substitution of saltpeter for chlorate of potash produced quiet ignition. Introduced in 1834. Then followed the substitution of saltpeter for chlorate of potash, so that both the original articles were superseded, greater safety and comfort being attain, and above all things in a cultivated estimation of the true value of a picture and of pictorial effects generally. See chromo-lithograph. Senefelder died in 1834. Every phase of the lithographic art described in the preceding sketch was indicated, originated, or practiced by him. Even chromo-lithography was suggested and alution in the art of figureweaving. Joseph Maria Jacquard was born at Lyons, 1752; invented his loom for weaving figured fabrics in 1801; and died at Orleans in 1834. The action of the Jacquard in producing patterns upon fabric may be briefly described as follows: — To the ordinary looms perforated cards are added, throug

bdued by the Moors. An authority states that it was known in Norway previous to 1266. Dr. Gilbert, physician to Queen Elizabeth, states that P. Venutus brought a compass direct from China in 1260. See Klaproth's work on this subject, Paris, 1834; Sir Snow Harris's Rudimentary magnetism ; the researches of Biot, Stanislaus Julien, etc. About 1320, Flavio Gioja, a pilot of Positano, not far from Amalfi in the Kingdom of Naples, was instrumental in the improvement of the compass, and for thean matches were made of a roll of paper treated with sugar and chlorate of potash and a small cell containing sulphuric acid. This cell was broken with a pair of pliers, and the acid ignited the composition by contact therewith. Next (about 1834) we find the Lucifers, which were coated with a mixture of sulphide of antimony and chlorate of potash made into a paste with gumwater, and ignited by drawing between the surfaces a folded piece of sand-paper.

It is sometimes provided with a diagonal object-glass having a mirror within the tube at an angle of 45° with its axis, so as to show objects without apparently being directed toward them.

It consists of a train of gear-wheels and pinions inclosed in a box and connected to or moved by the rotating shaft. A finger on the dial-plate indicates the count.
