dimeter (dimeter)

and n. [ two-, + μήκος , length, + ὀδών, Ionic for ὀδούς = E. tooth .] A notable genus of Japanese moles, of the family Talpida , related to Urotrichus , having teeth of two lengths (whence the name), and the anterior incisors broad and spatulate. The dental formula is: 3 incisors in each upper, 2 in each sion + -le .] Without dimensions or bulk. +-ed2.] Having dimensions. [Rare.] A mantle purple-ting'd, and radiant vest, Dimension'd equal to his size. Pope , Ody ey, xix. dimensionle (di-men's hon-les), a. [ lower half-jaw, 1 canine, 3 premolars, and 3 molars in each half-jaw. The type-species is D. pilirostris , having the general aspect of Urotrichus talpoides ; tail vertebræ half the length of the head and body, soles and palms entirely scaly, and snout pilose.

Sw. dimension, The and a solid three, length, breadth, and thickne . number of dimensions being equal to the number of principal axes, and that to the number of independent directions of extension, it has become usual, in mathematics, to expre the number of ways of spread of a figure by saying that it has two, three, or n dimensions, although the idea of measurement is quite extraneous to the fact expre ed. The word generally occurs in the plural, referring to length, breadth, and thickne . So doe those skils, whose quick eyes doe explore The just dimension both of earth and heaven. Sir J. Davies, Dancing, st. 95. Illimitable ocean, without bound, Without dimension , where length, breadth, and highth, And time, and place, are lost. Milton , P. L., ii. 893. A dark These as a line their long dimension drew, Streaking the ground with sinuous trace. Milton, P. L., vii. 480. Hence-2. A mode of linear magnitude involved (generally along with others) in the quantity to which it belongs. (a) In alg., a variable factor, the number of dimensions of an expre ion being the number of variable factors in that term for which this number is the largest. ( b ) In phys., a linear measure of length, time, ma , or any kind of quantity regarded as a fundamental factor of the quantity of which it is a dimension. If M, L, T, are the units of ma , length, and time, the dimensions of a velocity are said to be LT-1, or one dimension of length and minus one of time; those of an acceleration are said to be LT-2; those of a momentum, MLT-1; those of a force, MLT-2; those of a quantity of energy, MLT-2; those of the action of a moving system, MLT; those of a horse-power, MLT-3; those of a pre ure, ML-1T-2; those of a density, ML-3; etc. We are justified in considering the range, the flat pen cil, and the axial pencil, as of the same dimensions, since to every point in the first corresponds one ray in the second and one plane in the third. Cremona, Projective Geometry (tr. by Leuesdorf). 3. Bulk; size; extent or capacity: commonly in the plural: as, the question is a uming great dimensions.

All bodies have their measure and their space, But who can draw the soule's dimensive lines? Sir J. Davies, Nosce Teipsum, st. 88.
