Artificial baleen is made in Germany, and consists of rattans impregnated with a strong blackzontal axis so as to obtain the requisite direction of motion without intermediate gearing. In 1841, Whitelaw obtained a patent for an improvement, in which the horizontal arms assumed the form of r molasses to seventy gallons of water. This formed a soluble saccharate of lime. Warrington, 1841, employed carbonate of ammonia. Ba-tiste′. （Fabric.) a. A very fine, white, thick linen cred mill-boards about 1831.

h side of a piston. In Sir James C. Anderson's (English patent, No. 11,273), two cylinders open at the ends are placed end to end. A web of gun-cotton is fed to cylinders alternately and ignited by electric spark. Johnson's British patent of 1841 proposed to introduce pure hydrogen gas and oxygen instead of atmospheric air, in order that the water, the resultant of the explosion, might render the vacuum practically perfect. Otto and Langen's gas-engine is an upright hollow column, havint. The graving-dock of the Navy Yard at Brooklyn measures 350 feet in length within the caisson-groove, and the main chamber is 98 feet in breadth at the top. The width of entrance is 68 feet, and the depth of water 26 feet. It was commenced in 1841, and completed in 1851. Great difficulty was experienced in its execution, occasioned mainly by the softness of the foundations; upwards of 8,000 piles, varying from 25 to 40 feet in length, having been employed in the work, which is stated to ha

known substances. It has been used for forming the tips of gold pens. The alloy of iridium and osmium, called iridosmine, is the hardest of all alloys. It forms the point of the everlasting pen, made by Hawkins of England, and is ground by diamond-dust. Ir-i-dos′mine. An alloy of iridium and osmium. The hardest of all known alloys. Iris-cope. An instrument contrived by Dr. Reade for exhibiting the prismatic colors. Sir David Brewster describes it in the Phil. Trans. for 1841 as a plate of polished black glass, having its surface smeared with a solution of soap and dried by wash — leather. On breathing through a tube upon the glass, the vapor is deposited in brilliant colored rings. Iris-diaphragm. I′ris—dia-phragm. （Optics.)

the action of long-continued currents of low tension. (Phil. Trans., Vol. CXXVII. pp. 37 – 45.) Shore, 1840, used a solution of nitrate of nickel in one compartment of battery, and weak sulphuric acid and zinc in the other, for deposition of nickel. An alloy of nickel and tin made by melting under borax and glass was used for coating iron plates by Richardson and Braithwaite, 1840. The alloy was applied melted, as in tinning iron. Alfred Smee made an electro deposition of nickel in 1841. （Smee's Elements of Electro-Metallurgy.) Bottger, in the Journal fur Praktische Chemie, Vol XXX. p. 267, 1843, says that among all the salts of nickel the ammonio sulphate of protoxyde of nickel is especially useful in plating brass and copper, and is much superior to cyanide nickel of potash, as recommended by Ruolz. He proceeds at some length to state the effectiveness of the battery in producing a deposit of nickel on copper in half an hour, which would deflect the needle, and preser

stices being filled with pitch. Sand or ashes and tar was used in the foundation. Previous to 1841, a system of foundation-boards was exhibited in New York, and in 1841 the blocks were interlocked1841 the blocks were interlocked by notched shoulders. A pavement has been suggested, composed of iron perforated in such a manner as to afford a footing for horses, and to permit the sweepings to fall through upon a sub-pavement The permutation principle was introduced into tumbler-locks by Dr. Andrews of New Jersey, about 1841. The tumblers are capable of variable adjustment, and the key has a series of small shiftable st direction may be credited to the late Joseph Dixon of Jersey City, and to Lewis of Dublin, about 1841. Dixon's attempt was analogous to Poitevin's process, as described hereafter, and Lewis's was anarrels employed in that work. (See page 454, plate 45, in Buchanan's Practical essays, published 1841.)

Reed discharged the grain from the bed by rake-fingers proj revolving tower or turret, for offensive or defensive operations, was the work of Theodore R. Timby, of Saratoga, N. Y. The idea was conceived and a model made in 1841, caveated in 1843, and it was patented to him in 1862.
