An epithet given to fevers, the paroxysms and succession of symptoms of which are irregular.] [ACATSJAVALLI. An astringent and aromatic Malabar plant.] ACAULIS (a, priv.; Kav\bs, a cabbage- stalk). Acaulescent. Stemless ; a term ap- plied to certain plants, of which the stem is so short as to be almost reduced to no- thing. The term subcaulescent would be preferable in these cases. ACAWERJA. The Singalese designa- tion of the root of the Ophioxylon serpen- tinum, a supposed antidote to the venom of serpents. ACCELERATION (accelero, to hasten).

That which has a dependence on, or is se- condary to, some other. In anatomy, it is applied to certain muscles, ligaments, nerves, &c, which are joined to other simi- lar parts, and assist in their functions. In physiology, this term is given to certain phenomena which result from others which are primary or essential; such are the effects of the contraction of the diaphragm, in respiration, upon the abdominal viscera, the circulation, &c. In pathology, it is employed to designate certain phenomena which follow others without being a neces- sary consequence of them ; as the swelling in the arm-pit, resulting from whitlow, or injury of the hand, <fcc. Finally, it is ap- plied to several sciences, more or less inti- mately connected with medicine, but which hold a secondary rank, as respects the im- portance of a knowledge of them to the physician.] [ACCIDENT (accido, to happen).

A series of optical phenomena, so named by Buffon, and now known by the name of Ocular Spectra. If the eye be steadily directed, for some time, to a white wafer upon a dark ground, and be then turned aside, a well- defined image of the wafer will be per- ceived, with the colors reversed ; the wafer will appear dark, the ground white. This new appearance is termed the accidental color, or ocular spectrum. By using dif- ferently colored wafers, we obtain the fol- lowing results: Color of Wafer. Color of Spectra. Black White. Red Bluish Green. Orange Blue. Yellow Indigo „ f Violet, with Green [ a little Red. Blue Orange Red. * Indigo i Orange Yellow. Violet Bluish Green. Darwin classes the Spectra under the two heads of direct and reverse ; the for- mer depending upon the permanence of the impression, the latter upon exhaustion, ACCIPITRES (accipio, to take).

An obstetrician.] ACCRETION (accresco, to grow to). The addition of new parts, as in the for- mation of a crystal by the position of new parts around a central nucleus. The or- ganic and inorganic kingdoms are distin- guished by their mode of increase; the former increasing by intussusception and alimentation, the latter by accretion with- out alimentation. [ACCUMBENT. Lying against any thing, as the edges of the cotyledons against the radicle in some cruciferous plants.] -ACEOUS. Terminations in -aceons denote a resemblance to a substance, as
