214 ページ - ... silica in the cuticle of Equisetum, and in that of some of the grasses. In Lindley's ' Natural System of Botany,' the following account of Brewster's experiments is given : — " On subjecting a portion of the cuticle of Equisetum hyemale to the analysis of polarized light under a high magnifying power, Brewster detected a beautiful arrangement of the siliceous particles, which are distributed in two lines parallel to the axis of the stem and extending over the whole surface.
281 ページ - has a vacant portion in its centre, but the margin (which has a fluted appearance under a small magnifier,) consists of a number of parallel, linear-oblong, hyaline, hollow tubes, placed at small intervals from each other, those forming the angles of the scale being branched. Within these tubes are a profusion of globular, minute, orange bodies, (exactly similar to the sporules of other cryptogamic plants,) arranged in no order, and escaping on the least injury of the tubes. It is these little bodies...
214 ページ - Brewster detected a beautiful arrangement of the siliceous particles, which are distributed in two lines parallel to the axis of the stem, and extending over the whole surface. The greater number of the particles form simple straight lines, but the rest are grouped into oval forms, connected together like the jewels of a necklace, by a chain of particles forming a sort of curvilinear quadrangle, these rows of oval combinations being arranged in pairs.
214 ページ - Brewster also observed the remarkable fact, that each particle has a regular axis of double refraction. In the straw and chaff of wheat, barley, oats, and rye he noticed analogous phenomena, but the particles were arranged in a different manner, and ' displayed figures of singular beauty.
397 ページ - When the veins appear they are of a fine yellow, orange, or reddish brown, forming irregular folds, most frequently so arranged as to have the appearance of pores, but never anything like tubes, and distilling, when perfect, drops ot water.

xxxvii ページ - Perianth single, inferior, 5-cleft, persistent, enveloping the fruit with its base, and crowning it with its broad scariose limb. Seed solitary, its cotyledon spiral.
112 ページ - ... leaflets about 7, bright green, flat, simply serrated, orbicular or nearly so. Flowers solitary, without bracteas, cyathiform, blush coloured; peduncles naked, or rough with glands and setse, as are the calycine segments, which are short and entire ; tube ovate or nearly round, naked ; petals emarginate, concave; disk not thickened; styles villous, distinct. Fruit ovate or nearly round, black or dark purple, crowned by the connivent or somewhat spreading segments of the calyx.
464 ページ - This minute fungus found on apple trees, the hawthorn, pench trees, &c., is very common in spring and the beginning of summer. To gardeners it is well known as a kind of mildew, or blight, and is commonly taken for an insect. The leaves of peach trees, even when protected by glass, are often attacked by it, nor does the fruit itself always escape, in which case it frequently drops off. The leaves are more or less distorted by it. As its production is probably the result of a peculiar state of the...
