is called its glaze. The yellow or queen's-ware is made of the same materials as the flint-ware; but the proportion in which the materials are mixed is not the same, nor is the ware glazed in the same way. The flint-ware is generally made of four measures of liquid flint, and of eighteen of liquid clay. The yellow ware has a greater proportion of clay in it. In some manufactories they mix twenty, and in others twenty-four, measures of clay, with four of flint. These proportions, if estimated by the weight of the materials, would probably give for the flint-ware about 3 cwt. of clay to 1 cwt. of flint, and for the yellow ware somewhat more clay. The proportion, however, for both sorts of ware depends very much upon the nature of the clay, which is very variable even in the same pit. Hence a previous trial must be made of the quality of the clay, by burning a kiln of the ware. If there be teo much flint mixed with the clay, the ware, when exposed to the air after burning, is apt to crack; and, if there be too little, the ware will not receive the proper glaze from the circulation of the salt vapor. This glaze, even when it is most perfect, is in appearance less beautiful than the glaze on the i. Ware. The yellow glaze is made by mixing together in water, till it becomes as thick as cream, 112 lbs. of white lead, 24 lbs. of ground flint, and 6 lbs. of ground flint-glass. Some manufactories leave out the glass, and mix only 80 lbs. of white lead with 20 lbs. of ground flint; and others, doubtless, observe different rules, of which it is very difficult to obtain an account. The ware.before it is glazed is baked in the fire. By this means it acquires the property of strongly imbibing moisture. . It is therefore dipped in the liquid glaze, and suddenly taken out: the glaze is imbibed into its pores, and the ware presently becomes dry. It is then exposed a second time to the fire, by which means the glaze it has imbibed is melted, and a thin glassy coat is formed upon its surface. The color of this coat is more or less yellow, according as a greater or less proportion of lead has been used. The lead is principally instrumental in producing the glaze, as well as in giving it the yellow color; for lead, of all the substances hitherto known, has the greatest power of promoting the vitrification ef the substances with which it is mixed. The flint serves to give a consistence to the lead during the time of its vitrification, and to hinder it from becoming too fluid, and running down the sides of the ware, and thereby leaving them unglazed. The yellowish color which lead gives when vitrified with flints, may be wholly changed by very small additions of other mineral substances. Thus, to give one instance, the beautiful black glaze, which is fixed on one sort of the ware made at Nottingham, is composed of twenty-one parts by weight of white lead, of five of powdered flints, and of three of manganese. The queen'sware at present is much whiter than formerly. The coarse stoneware made at Bristol consists of tobacco-pipe clay and sand, and is glazed by the vapor of salt, like Staffordshire flint-ware; but it is far inferior to it in beauty. POTTLE, n.s.

POUSSIN (Nicholas), an eminent French painter, born in 1594, at Andel, in Normandy.

He was instructed for a few months by one Ferdinand Elle, a portrait painter, and spent a month with L'Allemant; after which he went to Italy to study the antique and bas relief, but neglected coloring. He was invited back to Paris by Louis XIII, who assigned him a pension with lodgings in the Thuilleries. Piqued by some insults from the faction of Vouet's school, he returned to Rome, where he died in 1665. He had during the whole of his life a perpetual demand for easel-pieces, for which he obtained large prices, Poussis, or DughET (Gaspar). This painter, whose real name was Dughet, was born in Paris in 1660. He went to Rome to see his sister, who was married to Nicholas Poussin; under whose instruction he became one of the best landscape painters that ever appeared. While he continued at Rome he assumed the name of his brother-in-law and benefactor, by which only he is now known. He died in 1662. POUT, n. s. From pouth.

These cases are usually from twelve to eighteen inches in length, and about eight or ten in breadth, having their outer or upper part terminating in an edge. They are nailed to several places of the quarter-deck and bulkhead of the waist, having atrain of powder which communicates with the inner apartments of the ship, so as to be fired at pleasure to annoy the enemy. They are particularly used in merchantships which are furnished with close-quarters to oppose the boarders.

Powders, FULMINATING, in chemistry, are

compositions which explode upon the application either of certain degrees | heat, trituration, or concussion. Under this title, therefore, are included several very distinct chemical combinations, the principal of which are those of azote, with the metals and alkalis. The common fulminating powder is thus made :-Triturate in a warm mortar three parts, by weight of nitre, two of carbonate of potass, and one of flowers of sulphur. A few grains of this laid upon a knife, and held over the candle, first fuse, and then explode with a loud report. A drachm of it put into a shovel, and held over the fire, makes a noise as loud as a cannon, and indents the shovel as if it had received a violent blow. If the mass be removed from the fire as soon as Vol. XVIII.

it is fused, and kept in a dry, well closed phial, it may at any time be exploded by a spark, and will burn like gunpowder, but more rapidly and with a greater report; but this effect will not be produced by unmelted powder. Whilst the powder is in fusion, but not sufficiently heated to produce the blue flame, a particle of ignited charcoal thrown upon it will immediately occasion a very loud explosion. The fulminating property of this powder is acquired by fusion, or when the potass and sulphur form sulphuret of potass. It may therefore be prepared by mixing sulphuret of potass with nitre, instead of adding the sulphur and alkali separate. If a solution of gold be precipitated by ammonia, the product will be fulminating gold. This precipitate, when separated by filtration, and washed, must be dried without heat, as it is liable to explode with no great increase of temperature; and it must not be put into a bottle closed with a glass stopper, as the friction of this would expose the operator to the same danger. Less than a grain of this, held over the flame of a candle, explodes with a very sharp and loud noise. Fulminating silver may be made by precipitating a solution of nitrate of silver by lime-water, drying the precipitate by exposure to the air for two or three days, and pouring on it liquid ammonia. When it is thus converted into a black powder, the liquid must be poured off, and the powder left to dry in the air. . It detonates with the gentlest heat, or even with the slightest friction, so that it must not be removed from the vessel in which it is made. If a drop of water fall upon it, the percussion will cause it to explode. It was discovered by Berthollet. Brugnatelli made a fulminating silver by powdering a hundred grains of nitre of silver, putting the powder into a beer-glass, and pouring on it, first an ounce of alcohol, then as much concentrated nitrous acid. The mixture grows hot, boils, and an ether is visibly formed, that changes into gas. By degrees the liquor becomes milky and opaque, and is filled with small white clouds. When all the gray powder has taken this form, and the liquor has acquired a consistency, distilled water must be added immediately to suspend the ebullition, and prevent the matter from being redissolved, and becoming a mere solution of silver. The white precipitate is then to be collected on a filter, and dried. The force of this powder greatly exceeds that of fulminating mercury. It detonates in a tremendous manner, on being scarcely touched with a glass tube, the extremity of which has been dipped in concentrated sul i. acid. A single grain, placed on a lighted coal, makes a deafening report. The same thing happens if it be placed on a bit of paper on an electric pile, and a spark drawn from it. M. Chenevix has invented a fulminating silver not so dangerous as that just mentioned. It explodes only by a slight friction in contact with combustible bodies. It is thus prepared:—Diffuse a quantity of alumina through water, and let a current of oxygenated muriatic acid gas pass through it for some time. Then digest some phosphate of silver on the solution of the oxygenated muriate of alumina, and * it

slowly. The product obtained will be a hyperoxygenated muriate of silver, a single grain of which, in contact with two or three of sulphur, will explode violently with the slightest friction. Fulminating mercury was discovered by Mr. Howard. A hundred grains are to be dissolved with heat in an ounce and a half by measure of nitric acid. The solution, when cold, is to be poured on two ounce measures of alcohol, and heat applied till an effervescence is excited. As soon as the precipitate is thrown down, it must be collected on a filter, that the acid may not react on it, and washed and dried by a very gentle heat. It detonates with a very little heat or friction. Of some experiments on the powers of this powder, the inventor gives the following account:— “Desirous of comparing the strength of the mercurial compound with that of gunpowder,’ says Mr. Howard, ‘I made the following experiment in the presence of my friend Mr. Abernethy:— Finding that the powder could be fired by flint and steel, without a disagreeable noise, a common gunpowder proof, capable of containing eleven grains of fine gunpowder, was filled with it, and fired in the usual way: the report was sharp, but not loud. The person who held the instrument in his hand felt no recoil : but the explosion laid open the upper part of the barrel, nearly from the touch-hole to the muzzle, and struck off the hand of the register, the surface of which was evenly indented to the depth of 0.1 of an inch, as if it had received the impression of a punch. “The instrument used in this experiment being familiarly known, it is therefore scarcely necessary to describe it; suffice it to say that it was of brass, mounted with a spring register, the moveable hand of which closed up the muzzle, to receive and graduate the violence of the explosion. The barrel was half an inch in calibre, and nearly half an inch thick, except where a spring of the lock impaired half its thickness. “A gun belonging to Mr. Keir, an ingenious artist of Camden Town, was next charged with seventeen grains of the mercurial powder, and a leaden bullet. A block of wood was placed at about eight yards from the muzzle to receive the ball, and the gun was fired by a fuse. No recoil seemed to have taken place, as the barrel was not moved from its position, although it was in no ways confined. The report was feeble: the bullet, Mr. Keir conceived, from the impression made on the wood, had been projected with about half the force it would have been by an ordinary charge, or sixty-eight grains of the best gunpowder. We therefore re-charged the gun with thirty-four grains of the mercurial powder; and, as the great strength of the piece removed any apprehension of danger, Mr. Keir fired it from his shoulder, aiming at the same block of wood. The report was like the first, sharp, but not louder than might have been expected from a charge of gunpowder. Fortunately Mr. Keir was not hurt; but the gun was burst in an extraordinary manner. The breech was what is called a patent one, of the best forged iron, consisting of a chamber 0.4 of an inch thick all round, and 0.4 of an inch in calibre; it was torn open and flawed in many directions, and the gold touch-hole driven out. The barrel into

which the breech was screwed was 0-5 of an inch thick; it was split by a single crack three inches long, but this did not appear to me to be the immediate effect of the explosion. I think the screw of the breech, being suddenly enlarged, acted as a wedge upon the barrel. The balled missed the block of wood, and struck against a wall, which had already been the receptacle of so many bullets that we could not satisfy ourselves about the impression made by this last. “As it was pretty plain that no gun could confine a quantity of the mercurial powder sufficient ...]." a bullet with a greater force than an ordinary charge of gunpowder, I determined to try its comparative strength in another way. I procured two blocks of wood, very nearly of the same size and strength, and bored them with the same instrument to the same depth. The one was charged with half an ounce of the best Dartford gunpowder, and the other with half an ounce of the mercurial powder; both were alike buried in sand, and fired by a train communicating with the powders by a small touch-hole. The block containing the gunpowder was simply split into three pieces; that charged with the mercurial powder was burst in every direction, and the parts immediately contiguous to the o were absolutely pounded, yet the whole ung together, whereas the block split by the gunpowder had its parts fairly separated. The *...]"surrounding the gunpowder was undoubtedly most disturbed; in short, the mercurial powder appeared to have a great superiority. During a lecture in the laboratory of Yale College, about 100 or 150 grains of fulminating mercury lay on a stool, and were covered with a glass receiver of about five or six quarts capacity. A small quantity of the same powder, at the distance of a few feet, was merely flashed by a coal of fire, but without explosion. In a manner not easily understood, the whole powder under the glass receiver instantly exploded with a dreadful report; but, what was particularly remarkable, the glass was merely lifted up a little, and was shattered by its fall, while the stool, made of fir plank, an inch and a half thick, on which the powder lay, had a hole blown quite through it, almost as large as the palm of the hand. The whole effect of the explosion was confined to the stool, every thing around having remained uninjured. An effect almost equally singular took place lately in the same laboratory, with some fulminating silver upon the point of a knife, which was about to be put upon a plate of copper, connected with one pole of a galvanic battery in active operation. The other pole was not touched by the experimenter, but, probably by the influence conveyed through the floor of the room, the powder exploded the moment the knife touched the plate of copper. The knife blade was broken in two, and one-half of it thrown to a distance among the audience. Three parts of chlorate of potassa, and one of sulphur, triturated in a metal mortar, cause numerous successive detonations, like the cracks of a whip, the reports of a pistol, or the fire o' musketry, according to the rapidity and force of
