e puddling-furnace. Helve-ham′mer. A ponderous blacksmith's hammer, tripped by the helve and oscillating on bearings. A trip-hammer. Hema-drom′e-ter. (Surgical.) An instrument for measuring the velocity of the blood in the arteries. Hema-dyna-mom′e-ter. (Surgical.) An instrument for measuring the force of the current of blood in the arteries, by ascertaining the high to which it will raise a column of mercury. Hemi-spheres of Mag′de-burg. Devised by Otto Guericke, 1654, to illustrate the pressure of the atmosphere. See Magdeburg-hemispheres. Hemmer. Hem′mer. An attachment to a sewing-machine for turning over the edge of a piece of fabric or a garment, in order that the flap may be stitched down. As the fabric is fed along, the edge is turned over in a curved path, and is then flattened by the presser-foot ready for stitching by the needle. Hemorrhoidal-syringe. Hemor-rhoid′alsyr′inge. (Surgical.) A form of injection-syrin
pheres. The example is a base-burning stove, having a fuel-magazine suspended free from the grate, and having an unobstructed free space around and below it, an illuminated casing surrounding it. See baseburning stove. Mag′de-burg Hem′i-spheres. Hemispheres of brass whose edges are carefully ground together to make an air-tight joint, and designed to illustrate the pressure of the atmosphere. The experiment originated with the worthy Otto Guericke, burgomaster of Magdeburg, about 1654. The edges of the hemispheres, being greased with oil or tallow, are brought together, the foot removed, and the stopcock screwed into the center of the air-pump plate. The cock being opened and a few strokes of the pump made, the sphere is thus exhausted of contained air, and on being removed from the plate and affixed to a duplicate handle is ready for the illustration. Nearly fifteen pounds of force to the square inch will be required to draw them asunder. To separate them readily, i
Restoration their number multiplied, but none appear to have been published oftener than once a week until about the reign of Queen Anne, when the demand for news from the Duke of Marlborough's army led to their being issued tri-weekly. The first London daily was the Courant, published by Samuel Buckley in 1703. The first established newspaper in England, outside of London, is believed to have been the Norwich postman, 1706. The first actually published in Scotland was at Edinburgh in 1654. The Dublin News-letter, the earliest Irish paper, was established in 1685. In the United States a newspaper was attempted as early as 1690. The first number was dated September 25 of that year, but its farther issue was prevented by the colonial government, it being published contrary to law, and containing reflections of a very high nature. In 1704 the Boston News-letter, published by authority, was established by John Campbell, and in 1719 the Boston gazette, also by authority. To
n chains supporting loops on which planking is laid, are mentioned by Hooker in his Himalaya journals. One crossed the Mywa, a western affluent of the Tambur in Nepal; another the Newa, in which the chains were clamped to the rocks on either shore, and the suspended loops occurred at intervals of 8 or 10 feet. Suspension-bridges in Europe are mentioned by Scamozzis in his Del idea Archi, 1615. The principles of their construction were laid down by Bernouilli (born at Bale, Switzerland, 1654; died in same city, 1705). The first chain-bridge in England appears to have been laid across the river Tees about the year 1741; its length was 70 feet, and breadth rather more than two; it was a mere foot-bridge, and seems to have been a very rude affair. Finlay constructed a chain-bridge in this country in 1796, over Jacob's Creek, between Uniontown and Greensburg, Pa., taking out a patent in 1801; in 1811 eight bridges had been built on his plan, which does not seem, however, to have
and marking off lengths of wire for hoop-skirts. The endless band carries dies for marking the wire as it is fed from a spool. The band is stretched over drums and under an ink-roller, and then passes between rollers, simultaneously with the wire to be marked. American wire and screw gage. Caliper, rule, and wire gage. Wire-mi-crom′e-ter. A comparison of authorities shows that two other forms of micrometer were used before the wire-micrometer was introduced by Malvasia, about 1654. These were the micrometer by Gascoigne, 1640, which consisted of nicely ground parallel edges of adjustable brass plates; and the slip of metal used by Huyghens, 1652. The latter was made to cover the image of the object in the focus of the lenses, and then compared with the breadth of the field. Hooke substituted parallel hairs for the parallel edges. Malvasia constructed a micrometer having two parallel series of crossing silver wires, which divided the field of view into squares o
