A vegetable acid found chiefly in unripe apples, as well as in plums, gooseberries, elderberries, barberries, and even in the houseleek. It becomes oxalic by the addition of nitric acid, and carbonic acid by distillation. See Chemistry.
(From malignus, evil). Malignity, when applied to fevers, means a high degree of putridity; and its signs are, a slight coldness and shivering, quickly followed by a great loss of strength, a small, quick, and contracted pulse, fainting, if in an erect posture, drowsiness without sleep, or the sleep not refreshing, but followed by a greater decay of strength and delirium. There is little pain, thirst, or other troublesome symptom, and yet the patient is uneasy, the features contract and sink, the extremities become cold, the pulse intermits, and death soon terminates the scene.
Cocyta. A pungent pain from an animalcule lodged in an ulcerous tumour; or pain from an insect lodged in any part without ulcer or tumour. The insects which produce this pain are various. In Persia it proceeds from the gordius medinensis, or dracuncu-lus persicus; in America by the pulex, and sometimes even by the pediculus.

See Tessor membhana tympani.
Mallei musculls internus. See Laxator membranae Tympani.
A mallet, and one of the bones in the ears. (See Auris). This bone hath a large round head, which contracts the whole way from the neck, whence the processus Ravianus arises, and on the outside a short process projects outward, pointing against the membrana tympani. From this part the manubrium or handle is continued down, and its extremity, fixed to the tympani membrana, pulls it inward. When the malleus is in its proper situation, the neck and head are turned upwards and inwards, the handle downwards, its short process upwards and outwards near the upper part of the edge or the tympanum, and the processus Ravianus forwards, reaching to the articular fissure in the os temporis, whence we may distinguish the malleus of one ear from that of the other. The handle of the malleus is tied to the membrana tympani by a fine membranous duplicature. This bone hath three muscles, viz. the laxator and tensor membrane tympani, and the mvsculus externus, auris Du Vernii.
