So the French call a disease, which resembles one in England, caused by eating bad corn. It consists of extreme debility, with mortification of the extremities, partly from the unalimentary nature of the substance; but more probably from the effect of some animalcule, for which the injured grain (generally rye) affords a nidus. The name is derived from the resemblance of the diseased corn to a cock's spur.


(From Erica 3662 to break; so called because it is broken to make besoms of). Erice, common heath, heather, ling. The flower is of a curious structure, and a decoction of the plant is recommended as a solvent for the stone; five ounces of it are to be drunk every night and morning. See Raii Hist. It is the erica vulgaris Lin. Sp. Pi. 501.


The name of several collyria in AEtius, so called from erica, heath, which is an ingredient.


(From Erigerum 3663 the spring, and old; because in spring it has a white blossom, like the hair of an old man), Simpson, and groundsel,called also, by Myrepsus, cortalon. It is a low plant, and too generally known to require a description. The species used in medicine, the senecio vulgaris Lin. Sp. Pi. 1216, is an annual plant; but may be found at all times of the year. The expressed juice of the leaves, or an infusion of them, is a powerful emetic and cathartic. A tea cupful of the juice will operate with maniacs as an emetic when other means fail, and thus slight attacks of the disorder may be removed. See Lewis's Materia Medica; and for its singular power externally applied, Edinburgh Medical Essays, vol. ii. art. 5.

Error Loci

(From erro, to deviate). Boerhaave introduced this term, from the opinion that the vessels were of different sizes for the circulation of blood, serum, and lymph; and that when the larger sized globules were forced into the lesser vessels by an error of place, they were obstructed. This opinion is, however, no longer adopted, as it originated fiomjnicrosco-pical observations, in which the conclusions were too hastily drawn.
