Samuel Johnson's Dictionary

  1. NITREnoun

    The salt which we know at this time, under the name of nitre or salt-petre, is a crystalline pellucid, but somewhat whitish substance, of an acrid and bitterish taste, impressing a peculiar sense of coldness upon the tongue. This salt, though it affords, by means of fire, an acid spirit capable of dissolving almost every thing, yet manifests no sign of its containing any acid at all in its crude state. Nitre is of the number of those salts which are naturally blended in imperceptible particles in earths, stones, and other fossile substances, as the particles of metals are in their ores: it is sometimes however found pure, in form of an efflorescence, either on its ores or on the surface of old walls; these efflorescences dissolved in proper water, shooting into regular and proper crystals of nitre. That this salt should be found on the surface of walls is not wonderful, since it is found only on or near the surface of the earth where it is produced. The earth from which nitre is made, both in Persia and the East-Indies, is a kind of yellowish marl found in the bare cliffs of the sides of hills exposed to the northern and eastern winds, and never in any other situation. From this marl the salt is separated by water; but the crystals into which it shoots, as we receive them from the East-Indies, are small, imperfect, and impure. Earths of whatever kind, moistened by the dung and excrement of animals, frequently afford nitre in large quantities. The earths at the bottom of pigeon-houses, and those of stables and cow-houses, all afford nitre, on being thrown into water and boiled. In France, where very little nitre is imported, they make it from the rubbish of old mortar and plaister of buildings; and the mortar of old walls with us, if moistened with urine and exposed to the air in a proper situation that is open to the north east, and covered over to defend it from wet, never fails to afford nitre in a few weeks, and that in proportion of one tenth of the weight of the ingredients. There is no question but a manufactory of nitre might be established in England to as much advantage as that of France. The place where the materials are exposed, is to be carefully examined. It must be moderate as to the great points of moisture and dryness; if there be too much moisture the nitre which is already formed will be washed away, and without some moisture the salts will hardly be ever formed. Heat and coldness, unless excessive, can be of no consequence. It is on account of the requisiteness of so certain a degree of moisture to the materials from which nitre is obtained, that the north east winds are of so much use in the production of it. In spring and autumn, which are the seasons when this salt is principally made, these two winds are neither too moist nor too dry, especially in the night; the south and west winds are destructive, because they bring storms and showers. In medicine, nitre is cooling and diuretick, and good in burning fevers. The natrum or nitre of the ancients, is a genuine, native, and pure salt, extremely different from our nitre, and from all other native salts; being a fixed alkali plainly of the nature of those made by fire from vegetables, yet being capable of a regular crystallization, which those salts are not. It is found on or very near the surface of the earth, in thin flat cakes, spungy, light, and friable; and when pure, of a pale brownish white colour. It is of an acrid taste, like pot-ashes. About Smyrna and Ephesus, and through a great part of Asia Minor, this salt is extremely frequent on the surface of the earth, and also in Sindy, a province of the inner Asia, where they sweep it up and call it soap-earth, using a solution or lye of it in washing. The natrum or nitre of the ancients, has been by some supposed to be a lost substance, and by others to be the same with our nitre or salt-petre; but both these opinions are erroneous, this salt being the true natrum of the ancients, answering perfectly to its description, and having all its uses and virtues. In scripture we find that the salt called nitre would ferment with vinegar, and had an abstersive quality, properties which perfectly agree with this salt but not with salt-petre, as do many different qualities ascribed to it by the ancients. John Hill on Foss.

    Etymology: nitre, Fr. nitrum, Latin.

    Some tumultuous cloud,
    Instinct with fire and nitre, hurried him. John Milton.

    Some steep their seed, and some in cauldrons boil,
    With vigorous nitre and with lees of oil. Dryden.
