Brob. （Carpentry.) A peculiar form of spike driven alongside a timber which makes a buttjoint against another, to prevent the slipping of the former. For instance, several brobs are driven round a post which supports a rooftimber in a tunnel or gallery. Brob. Bro-cade. （Fabric.) A rich, stout silk. A common name for any kind of stuff wrought and enriched with raised flowers. In the East, a cloth of gold and silk. The manufacture of brocade was established at Lyons, in 1757.

occupying a well or water-tight curb which was open at each end. The long pile formed a guide, causing the caisson to settle correctly into position. The guide-pile has been occasionally used, but is by no means a necessary feature of the work. When the work is concluded, the sides of the caisson are knocked away, leaving the pier in position, as shown in the illustration. a represents the sinking of the caisson. b, the pier on its foundation. The caissons used by De Cessart in 1757 for the piers of the bridge at Saumur were sunk upon a foundation of piles, the heads of which were previously cut off to a level of about six feet below the water-surface. Each caisson was 48 × 20 feet, the ends being pointed and the sides removable, so that they could be used with another bottom after the masonry was laid nearly to the water-line. The bottom had a floor of lower beams laid side by side, and planks 14 inches thick, and the frame timbers were rabbeted to receive the upright

it; boring. Ducks-foot pro-pel′ler. A collapsing and expanding propeller which offers but little resistance in the non-effective motion, but expands to its full breadth in delivering the effective stroke, forming a kind of folding oar which opens to act against the water when pushed outward, and closes when drawn back at the end of the stroke. The idea was taken from the foot of a duck, and was first tried by the celebrated Bernoulli, afterwards by Genevois, a Swiss clergyman, about 1757; then by Earl Stanhope about 1803. It was used on the river Thames about 1830. Dumb-bells. Dumb-furnace. Nairn's propelling apparatus, English patent, 1828, has the contractile retreat and expanding advance, the advance being understood to mean the effective stroke. Duc′ti-lim′e-ter. An instrument invented by M. Regnier for ascertaining the relative ductility of metals. The metal to be tested is subjected to the action of blows from a mass of iron of given weight attached to<

keep them in order. The expense was defrayed by the county. Pitch boxes were made use of in the reign of Edward III. Lighthouses. The Eddystone lighthouse (b) is erected upon a rock of that name ten miles from shore, off Plymouth, England. A lighthouse was built on the spot, 1696-99, by Winstanley, who perished with it in a storm, November 27, 1703. Rebuilt of wood in a different form by Rudyard, 1706, and burnt 1755. Rebuilt by Smcaton of dovetailed and metal-bound granite blocks, 1757. The surface of the rock was irregular and inclined. It was cut into steps, the risers of which were notched so as to form dovetailed mortises for the similarly shaped blocks of the stones in the course which interlocked with it. Each block had a level bearing, and the outside pieces were guarded by a border of rock which rose around them. The stones in a course were dovetailed together and additionally secured by cramps. The respective courses were secured to those above and below by d

scuit in a hardening-kiln, previous to glazing. In bat-printing, the lines of the engraving are more delicate. The impression is taken in linseedoil on a slab of damp glue, and transferred from thence to the glazed ware. Color is then dusted on to the oil, and the ware is fired in an enamel kiln. Printing on porcelain, or the transferring of printed impressions to biscuit, was introduced by Dr. Wale of Worcester about 1751. The Prussians refer the discovery of the process to the year 1757. Porch. （Architecture.) A covered entrance to a building. With a row of columns it is a portico. Porch-post Sup-port′. A casting placed between the foot of a post and the floor of a porch to prevent decay of the two at that point. Por′cu-pine. （Fiber.) A heckling apparatus for flax; or a cylindrical heckle for worsted yarn. Porphy-ri-za′tion. A mode of grinding substances by a muller upon a slab. Porphyry, from its extreme hardness, is eminently suitable, and

was in regard to portraits made by Elizabeth Pyberg, who cut the profiles of William and Mary out of black paper, 1699. The name silhouette was given them, about 1757, in derision of the French Minister of Finance, Etienne Silhouette, he having vexed the people of Paris by many salutary and some rather trifling reforms; the wits we indebted for the effective machine. Arkwright was but two years old when Lewis Paul patented an improved spinning-machine. Dyer, in his poem of The fleece (1757), celebrates Paul's machine, as follows:— But patient art, That on experience works, from hour to hour, Sagacious, has a spiral engine formed, Which, on a hundengine, and obtained a rotary motion by an arrangement of cords and pulleys. This was before Watt's application of the crank to the steam-engine See crank. In 1757 Bernouilli (French) and Genevois (Swiss) experimented with steamboats, the first using a kind of artificial fin, and the latter the duck's-foot propeller. In 17

s, one pair twice the length of the others, so that their respective reaches are as 2 to 1. A kind of reducing or enlarging compass. The Herculaneum cabinet shows a pair of such, and the same may be seen in Ficoroni, Gem. Liter., tab. 6, 4to, 1757. Such are also seen in the Pompeiian collection. Also known as a bisecting-compass. Whole-and-half compass. Whorl′er. A potter's whirling-table, on which he shapes circular articles. Wick. A bundle of fibers to lead oil to the fly bridges of considerable magnitude, both in Europe and America, among others that over the Regnitz, near Bomberg, designed by Wiebeking, and built in 1809 (e, Fig. 7319). The celebrated wooden bridge over the Rhine, at Schaffhausen, erected in 1757, had a span of 364 feet. A stone pier, the relic of a former structure, existed near the middle of the stream, but it is said that the builder. Ulric Grubenmann, though erecting the bridge directly over this pier, in deference to the timidity of
