of light, does not consist in the change of position of isolated grains, but of masses of network, each containing a certain number of grains. In addition, M. E. Roze states that, besides the grains of chlorophyll which coat the walls of the cell, each cell is lined with a transparent mucous plasma formed of very fine threads, the extremities of which unite together the grains of chlorophyll. This protoplasm exhibits, under a high magnifying power, a very slow motion, and carries the grains of chlorophyll along with it. M. Roze believes, therefore, that the motion is a plasmic one, the protoplasm being the vital and animating part of the cell. CARNATIONS AND PINKS. Among the latest flowers of the autumnal garden are those old favourites, the "July-flowers," or _Carnations_, which, because they were "fair and sweet and medicinal," Jeremy Taylor preferred to "the prettiest tulips, that are good for nothing." I remember a time when they were among the best-prized ornaments of our parterres, and very delicious it was to inhale the balmy breath that rose into the warm air of an autumn evening from rich masses of carnations and pinks. The carnations were also called--_sub consule Planco_--in the merry days when I haunted the green lanes of a pretty Devonshire village, carnations, and clove July-flowers or gilliflowers; and an ancient name for the pink was that of sops-in-wine, because they were infused in the wine-cups of our much-drinking ancestors. So Drayton says:-- "Bring hither the pink and purple columbine, With gilliflowers; Bring coronations, and sops-in-wine, Worn of paramours." The same poet alludes to them under their more modern appellations:-- "The brave carnation, then, of sweet and sovereign power (So of his colour called, although a July flower), With the other of his kind, the speckled and the pale;-- Then the odoriferous pink, that sends forth such a gale Of sweetness, yet in scents as various as in sorts." The scientific name of this beautiful family of plants, whose rich dyes are not less conspicuous than their Sabæan odours, is _Dianthus_, or "Flower of God." They form a genus of the natural order Carophyllaceæ; the calyx is tubular, and five-toothed; there are five petals, which at the throat of the corolla are lightened (as it were) into a linear "claw." The stamens are double the number of the petals; the capsule is of a cylindrical outline, and one-celled. [Illustration: FIG. 79.--"When I haunted the green lanes of a Devonshire village."]
