    Oniscus armadillo. (Linn., Gmel.) Armadillo vulgaris. (Lat.) Cloporte armadillo. (Geoff.) Millepedes, common armadillo, or Pill Millepede. This animal is commonly met with amongst moss, and under stones. Its length is rather more than half an inch. The body is elongate- ovate, somewhat convex above, smooth, and consists of ten crustaceous semicircular scales, or segments of a cinereous lead colour; the poste- rior margin of the segments are whitish. It has seven pairs of very short legs, each terminated by a minute horny claw. When touched, it rolls itself up into a ball, like the singular quadrupeds called Arma- dillos. Millepedes are prepared by exposing them to the vapour of hot alcohol, which kills them. In this state they are always contracted into the globular form, and are thus distinguished from wood-lice, which have sometimes been confounded with them. They were formerly administered in medicine, and considered to be expectorant, aperient, and diuretic. Oniscus asellus. (Gmel.) Oniscus murarius. (Fabr.) Cloporte ordinaire. (Geoff.) The Wood-louse, Sow-louse, Church-louse, Pig's- louse, or Carpenter. The French name, Cloporte, applied to this and the preceding species, is abbreviated from Clous-a-porte. The wood-louse is met with throughout Europe, in rotten wood and old walls. It is somewhat larger than the millepede, being about three-fourths of an inch in length. The body is oval, with crustaceous imbricate segments, rough above, and of a livid brown, or dirty ash-colour; the sides are yellowish, and the belly nearly white. The body is not capable of contracting; into a ball. CLASS IIL ARACHNIDA. (Class XIIL of General Division.) The Arachnida, comprising the third class of articulated animals, provided with moveable feet, are, as well as the Crustacea, deprived of wings, are not subject to changes of form, or do not experience any metamorphosis, simply casting their skins. They differ from the Crustacea, as well as from insects, in several particulars. Like the latter, the surface of their body presents apertures called stigmata, for the introduction of air. Respiration is effected either by air-branchiae, or by radiated tracheae. Most of the Arachnida feed on insects, which they either seize alive, or to which they adhere, abstracting their fluids by suction. Others are parasitical, and live on vertebrated animals. Some are found in flour, cheese, and in various vegetables. The Arachnida are divided into two orders: 1. Pulmonaria. 2. Trachearia. The former have pulmonary sacs, a head with distinct vessels, and six or eight ocelli. The Trachearite respire by trachete, and have no organs of circulation, or if they have, the circulation is not complete. Acarus scabiei. Sarcoptis hominis, (Raspail.) The Itch Acarus. This little animal is thought by some to be the cause of the disease
