The definition of Axe is followed by practically usable example sentences which allow you to construct your own sentences based on it. In the true raceme, however, we find only a single axis, producing in succession a series of bracts, from which the floral peduncles arise as lateral shoots, and thus each flower is on the same side of the floral axis as the bract in the axil of which it is developed; but in the uniparous cyme the flower of each of these axes, the basal portions of which unite to form the false axis, is situated on the opposite side of the axis to the bract from which it apparently arises (fig. The ordinary position of a pair of endless screws is with their axes at right angles to each other. 2. flowers are produced, they belong to secondary axes farther from the centre; or the axis is shortened and flat tened, producing a number of separate floral axes, the central f„ one expanding first, while the others are developed in succession farther from the centre. If we write A=Ma, B=M/32, C=M~y, the formula (37), when referred to the principal axes at 0, becomes if p denotes the perpendicular drawn from 0 in the direction (X, u, e) to a tangent plane of the ellipsoid ~+~+~=I (43). The effect of the link is to maintain the distance between the axes of those pins invariable; hence the common perpendicular of the axes of the pins is the line of connection, and its extremities may be called the connected points. 22) are attached to the plate L, their optical axes being normal to the stage T. Thus it has a real centre, two foci, two directrices and two vertices; the transverse axis, joining the vertices, corresponds to the major axis of the ellipse, and the line through the centre and perpendicular to this axis is called the conjugate axis, and corresponds to the minor axis of the ellipse; about these axes the curve is symmetrical.

Or, instead of looking upon a linear substitution as replacing a pencil of lines by a projectively corresponding pencil retaining the same axes of co-ordinates, we may look upon the substitution as changing the axes of co-ordinates retaining the same pencil. The origins of these four plane co-ordinate systems may be collinear with the axis of the optical system; and the corresponding axes may be parallel. The morphology of Stigmaria has been much discussed; possibly the main axes, which do not agree perfectly either with rhizomes or roots, may best be regarded as comparable with the rhizophores of Selaginellae; they have also been compared with the embryonic stem, or protocorm, of certain species of Lycopodium; the homologies of the appendages with the roots of recent Lycopods appear manifest. Sliding Contact: Forms of the Teeth of Spur-wheels am Racks.A line of connection of two pieces in sliding contact is line perpendicular to their surfaces at a point where they touch Bearing this in mind, the principle of the comparative motion of pair of teeth belonging to a pair of spur-wheels, or to a spur-whee and a rack, is found by applying the principles stated generally ii 36 and 37 to the case of parallel axes for a pair of spur-wheels, am to the case of an axis perpendicular to the direction of shifting for wheel and a rack.
