INTRODUCTION.
ОглавлениеThe Foxglove is a plant sufficiently common in this island, and as we have but one species, and that so generally known, I should have thought it superfluous either to figure or describe it; had I not more than once seen the leaves of Mullein[1] gathered for those of Foxglove. On the continent of Europe too, other species are found, and I have been informed that our species is very rare in some parts of Germany, existing only by means of cultivation, in gardens.
Our plant is the Digitalis purpurea[2] of Linnæus. It belongs to the 2d order of the 14th class, or the Didynamia Angiospermia. The essential characters of the genus are, Cup with 5 divisions. Blossom bell-shaped, bulging. Capsule egg-shaped, 2-celled.—Linn.
DIGITA'LIS purpu'rea. Little leaves of the empalement egg-shaped, sharp. Blossoms blunt; the upper lip entire. Linn.

Blossom. The bellying part on the inside sprinkled with spots like little eyes. Leaves wrinkled. Linn.
Blossom. Rather tubular than bell-shaped, bulging on the under side, purple; the narrow tubular part at the base, white. Upper lip sometimes slightly cloven.
Chives. Threads crooked, white. Tips yellow.
Pointal. Seed-bud greenish. Honey-cup at its base more yellow. Summit cloven.
S. Vess. Capsule not quite so long as the cup.
Root. Knotty and fibrous.
Stem. About 4 feet high; obscurely angular; leafy.
Leaves. Slightly but irregularly serrated, wrinkled; dark green above, paler underneath. Lower leaves egg-shaped; upper leaves spear-shaped. Leaf-stalks fleshy; bordered.
Flowers. Numerous, mostly growing from one side of the stem and hanging down one over another. Floral-leaves sitting, taper-pointed. The numerous purple blossoms hanging down, mottled within; as wide and nearly half as long as the finger of a common-sized glove, are sufficient marks whereby the most ignorant may distinguish this from every other British plant; and the leaves ought not to be gathered for use but when the plant is in blossom.
Place. Dry, gravelly or sandy soils; particularly on sloping ground. It is a biennial, and flowers from the middle of June to the end of July.
I have not observed that any of our cattle eat it. The root, the stem, the leaves, and the flowers have a bitter herbaceous taste, but I don't perceive that nauseous bitter which has been attributed to it.
This plant ranks amongst the LURIDÆ, one of the Linnæan orders in a natural system. It has for congenera, Nicotiana, Atropa, Hyoscyamus, Datura, Solanum, &c. so that from the knowledge we possess of the virtues of those plants, and reasoning from botanical analogy, we might be led to guess at something of its properties.
I intended in this place to have traced the history of its effects in diseases from the time of Fuchsius, who first describes it, but I have been anticipated in this intention by my very valuable friend, Dr. Stokes of Stourbridge, who has lately sent me the following
