After all, in spite of opinion, prejudice, or error, Time will fix the real value upon this discovery, and determine whether I have imposed upon myself and others, or contributed to the benefit of science and mankind.

INTRODUCTION.


The 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.
