SOOKRBAR, Ind. Friday.

SOORETHAUL, Ind. Statement of a case.

SORDET, SORDINE, The small pipe or mouth piece of a trumpet.

SORN, a servile tenure in Scotland, by which a chieftain might, with his followers, live upon his tenants at free quarters.

SORTIES, in a siege, parties that sally out of a town secretly to annoy the besiegers, and retard their operations.

SOUDOYES, Fr. From Soudoyer. To keep in pay. This name was originally given to a body of men who inlisted themselves under Philip Augustus of France, on condition that they should receive a certain daily pay in the way of subsistence. Froissart calls all soldiers, who are paid for doing duty, or for going to war, soudoyes,

SOUFLE, Fr. The wind of a cannon.

SOUFLER les canons, Fr. To scale pieces of ordnance. This is done by means of a moderate charge of gunpowder, for the purpose of cleaning them.

SOUFLURE, Fr. A cavity or hole, which is frequently occasioned when pieces of metal have been forged in too intense a fire. Cannon balls lose their required weight by flaws of this sort.

SOUFRE, Fr. See SULPHUR.

SOUGARDE, Fr. Guard, throat-band of a gun. A semi-circular piece of brass which ts fixed beneath the trigger of a musquet, to prevent it from going off by accident.

SOUGARDES. See DECHARGEURS.

SOUGORGE, Fr. Throat-band of a bridle.

SOUKARS, Ind. A general name for bankers.

SOULEVEMENT, Fr. Insurrection, revolt.

SOULEVER, Fr. To stir up, to excite to insurrection.

Se SOULEVER, Fr. To rise, to revolt, to mutiny; l’armee s’est soulevee contre son general; the army rose, or mutinied against its general.

SOUMETTRE, Fr. (As an active verb) to subdue, to overcome, to reduce to subjection.

Se SOUMETTRE, Fr. To submit oneself. To yield.

SOUMISSION, Fr. Submission.

SOUMIS, ise, Fr. In fortification; to lie under, to be commanded. Thus one work is said to be commanded, ou être soumis, when it is lower than another. The same signification holds good with respect to heights or elevations.

SOUND. Any thing audible; noise; that which is perceived by the ear. The experiments are numerous by which it has been found, that sound is audible to the distance of 50, 60, or 80 miles; but Dr. Hearne, physician to the king of Sweden, tells us, that at the bombardment of Holmia, in 1658, the sound was heard 30 Swedish miles, which make 180 of ours: and in the fight between England and Holland in 1672, the noise of the guns was heard even in Wales, which cannot be less than 200 miles.

The velocity of sound is 380 yards, or 1142 feet in a second of time, as found by very accurate experiment. The exactness of measuring distances by sound, has been sufficiently proved by measuring the same distances by trigonometry.

The medium velocity of sound is nearly at the rate of a mile, or 5280 feet in 4²⁄₃ seconds; or a league in 14 seconds; or 13 miles in one minute. But sea miles are to land miles nearly as 7 to 6: therefore sound moves over a sea mile in 5³⁄₄ seconds nearly; or a sea league in 16 seconds.

Sound flies 1142 feet in one second.

It is a common observation, that persons in good health have about 75 pulsations at the wrist in a minute, consequently in 75 pulsations sound flies about 13 land miles, or 11¹⁄₇ sea miles, which is about 1 land mile in 6 pulsations, and 1 sea mile in 7 pulses, or a league in 20 pulses.

The velocity of sound does not very much vary, whether it goes with the wind or against it. As sound moves vastly swifter than the wind, the acceleration it can thereby receive can be but inconsiderable; and the chief effect we can perceive from the wind is, that the sound will be carried to a greater distance by it. Sound will be louder in proportion to the condension of the air. Water is one of the greatest conductors of sound; it can be heard nearly twice as far as on land.
