Steamer
or RACE-HORSE DUCK (Micropterus brachypterus), a species of marine duck from 35 to 40 inches in length, distinguished by its small, short wings, and the swiftness with which it paddles over the surface of the water. It is found in Patagonia and the Falkland Islands.

Stearates
compounds of stearic acid with the alkalies and metals. They have the consistence of hard soaps and plasters, and are mostly insoluble in water. Stearate of potassium, C18H35 KO2, separates on cooling from a solution of one part stearic acid and one part potassic hydrate in 10 parts of water. It forms shining delicate needles, having a faint alkaline taste, and dissolves in 6.7 parts boiling alcohol and 25 parts boiling water. Acid stearate of potassium, C18H35KO 2-C18H36O2, obtained by decomposing the neutral salt with 1,000 parts of water. When dried and dissolved in alcohol it separates in silvery scales inodorous and soft to the touch. It dissolves in four parts of boiling absolute alcohol.

Stearic Acid
in chemistry C18H35O. OH, an acid discovered by Chevreul, and found as a frequent constituent of fats derived from the animal and vegetable kingdoms, and especially abundant as a tristearin in beef and mutton suet. It may be obtained by saponifying the fat with soda lye, decomposing with sulphuric acid, dissolving the fatty acids in alcohol, and repeatedly crystallizing, the first portions of the fatty acid only being taken. When pure it crystallizes from alcohol in nacreous laminæ or needles, needles, is tasteless and inodorous, and has a distinct acid reaction. Its specific gravity is nearly that of water, it melts at 69- 69.2°, distills in a vacuum without alteration, and is sparingly soluble in alcohol, more so in ether and benzene.

Stearin
in chemistry, a compound of stearic acid and glycerin. Stearin is the chief component of suet, tallow, in short of the harder fats. When freed from fat and crystallized, stearin takes the form of white, pearly scales, soft to the touch but not greasy. Pure stearin is tasteless and odorless. It is insoluble in water but is soluble in alcohol and ether. It is used in the manufacture of certain chewing gums. Stearin may be separated into stearic acid and glycerin. Stearic acid, more or less pure, is the material of wax candles. An impure stearin may be obtained from lard by pressing out the oil. To properly comprehend the subject, the reader should disabuse his mind of any notion that an acid is necessarily a liquid.

Stearine
or STEARIN, in chemistry, C57H11006, the chief ingredient of suet and tallow, or the harder ingredient of animal fats, oleine being the softer one. It is obtained from mutton suet by repeated solution in ether and crystallization. It may also be obtained by pressing tallow between hot plates, and afterward dissolving in hot ether, which on cooling deposits the stearine. It has a pearly luster, is soft to the touch, but not greasy. It is insoluble in water, but soluble in hot alcohol and ether. When treated with superheated steam it is separated into stearic acid and glycerin, and when boiled with alkalies is saponified, that is, the stearic acid combines with the alkali, forming soap, and glycerin

Steel Engraving
the art of engraving on steel plates for the purpose of producing prints or impressions in ink on paper and other substances. The process of decarbonizing steel so that it could be engraved was invented by Jacob Perkins, of Newburyport, Mass., in 1814.

Steel-faced Castings
A face of steel may, under favorable conditions, be given to castings in iron, by making the steel red-hot, and placing it within a dry-sand mould. If possible, drop the molten iron immediately over the steel to be welded, by runners sufficient to cover the piece and effect a junction quickly; otherwise the process is rendered inoperative by the metal simply running over it and out at the escape, at a gradually decreasing temperature--just so much waste. A very superior union is always effected when the body of cast iron is large, the steel being under the influence of fluid metal for a less space of time in proportion as the body becomes thinner. Sometimes these junctions are effected, apparently, by forcing a large quantity of molten metal through the mould; but if the steel is not subjected to the abrading influence of a direct fall, it can hardly be expected that a solid weld will be made.
