    • n lead Chemical symbol, Pb; atomic weight, 206.9. One of the useful metals, remarkable for its softness and durability. It belongs to the class of white metals, but has a decided bluish-gray tint, expressed by the common term “lead-gray.” The freshly cut surface is lustrous, but it soon becomes dull from the formation of a film of oxid. Lead is the softest metal in general use; it can be scratched by the finger-nail, and is easily cut with a knife. It is very malleable, and can be rolled into thin sheets; but it cannot be drawn into fine wire. Lead rarely occurs in the native form; as a general rule, and possibly in every instance, the particles of the metal thus found are associated with some ore of lead, or occur in such a manner as to indicate that they are of secondary origin. The most important localities of native lead are in Sweden, near Pajsberg, where this metal occurs in small filiform masses and scaly grains, associated with magnetite in dolomite, and also near Nordmark, where pieces several ounces in weight have been obtained. Native lead has also recently been found crystallized in various forms belonging to the isometric system. Its specific gravity is about 11.4. It fuses at about 617°; when heated before the blowpipe on charcoal, it is volatilized, leaving a yellow incrustation. The ores of lead are numerous and widely distributed, occurring in many countries in very considerable quantify. The most important of these ores is the sulphuret (galena), which contains 86½ per cent. of the metal. This ore is found in greater or less quantity in a very large number of metalliferous veins, especially such as produce gold and silver. Galena almost always contains at least a trace of silver, and in most regions the quantity of the precious metal is sufficient to make its separation profitable. (See Pattinson process and Parkes process, under process.) The carbonate of lead (cerusite) is also an important ore of this metal, and so is the sulphate (anglesite), but in less degree. These ores also usually contain silver in paying quantity, and the value of the precious metal is frequently greater than that of the lead itself. One of the chief uses of lead is for service-pipes in the supply of houses with water, a purpose for which the ductility and flexibility of this metal admirably adapt it. A serious drawback, however, is its liability to oxidation and the poisonous nature of the resulting combination, and to overcome this tendency lead pipes are often lined with tin. Another important use of lead is as the base of oil-painting, for which purpose it is used in the form of the carbonate. (See white lead, below.) Lead is also much used in the form of shot and bullets. The most important alloy of which lead forms a part is pewter.
    • n lead A plummet or mass of lead attached to a graduated line, used in sounding at sea. It is usually in the shape of the frustum of a cone or pyramid. For depths of 20 fathoms or under, it has a weight of from 5 to 9 pounds, and is called a hand-lead. For depths from 20 to 60 fathoms, the lead weighs from 20 to 60 pounds, and is called a coasting-lead. For depths from 60 to 200 fathoms, a deep-sea lead is used, weighing from 75 to 120 pounds. A special apparatus, called a deep-sea sounding-machine, is used for depths above 200 fathoms. See deep-sea sounding-machine, under deep-sea.
    • n lead In printing, a thin strip of type-metal (sometimes of brass), used to increase the space between lines of composed types. Leads are usually cast to fractional parts of the body pica. The thickness most used is six-to-pica, one thirty-sixth of an inch, but there are many sizes both above and below this. To make matter still more conspicuous, double leads (two leads together) are often used, and sometimes treble leads.
    • n lead A small stick of black-lead or plumbago used in pencils.
    • n lead plural Sheets or plates of lead used for covering roofs: sometimes used as a singular for a flat roof covered with lead.
    • n lead A pipe of lead; a leader.
