Scurvy-Grass, or Cock-learia, L. genus of plants comprising eight species, five of which are indigenous ; and the principal of these are :

1. The Armoracia, See Horseradish.

2. The officinalis, Common Scurvy-Grass, Or Scruby-GrAss ; growing on sea-shores, and in mountainous situations, where it flowers in the months of April and May. - When cultivated in gardens, this maritime plant retains its properties, without any sensible change. It possesses a considerable degree of acrimony, which resides in a very subtle essential oil: and, as an antiscorbutic, its effects are sufficiently ascertained. In the pitui-tous asthma, and chronic rheumatism, the scurvy-grass is a powerful remedy. It is likewise a pungent stimulating medicine, which may be advantageously employed for promoting the fluid secretions. - A distilled water, and a conserve, are prepared from its leaves ; and the expressed juice is prescribed with that of oranges, among other antiscorbutics. - It may aiso be used as a salad. - Cows cat this plant, but it is refused by horses, goats, and sheep.

The Anglica, English Scurvy-grass, or Spoonwort, grows on - res, in muddy soils, or salt-marshes and flowers in the month of May. - This species possesses similar properties with the preceding, but in an inferior degree.

4. The Coronopus, Common Wort-cress, or Swine's-cress, thrives in corn-fields, on rubbish, and road-sides; blows from June till August. - It is a palatable salad-herb, on which account the Germans cultivate it in gardens. These different species of scurvy-grass may be propagated by seeds, which are to be sown in July, in a moist soil; because, if committed to the ground in the spring, they seldom prosper : - when the young plants appear, they should be thinned, so as to leave them at the distance of about six inches apart. Those of a proper size may then be transplanted; and, in the scucceeding spring, they will be fit For use : the remaining plants may be left for seed, which will attain to maturity in the month of June.
