D. CALDWELL, Clerk of the District of Pennsylvania. Text 828.3e 1837 PREFACE. THE new edition of my Elements of Botany being now completed, as far as I am able to complete it, the work is presented to the public, with a confident persuasion, that it will be found much more perfect than the former edition. Besides many corrections, or minor additions, and besides the new plates,-ten in number,— which the present edition contains, it is easy to perceive, that it is much enlarged, especially by the addition of two entire sections, in Part Second: and by much new matter in Part Third. The principal of these additions have, indeed, been hinted at, or pointed out, in the Preface to the First volume. THE work, the author is fully sensible, is still imperfect; and it must continue so, until a future, perhaps very distant period, when a third edition may, possibly, be called for by the public. In the meanwhile, he flatters himself, that the Elements of Botany, originally published under great difficulties, in sickness, and at his own expense, will not cease, in a more improved style, to be read, or consulted, by the American student of botany, by the scientific agriculturalist, by the amateur of plants. ALTHOUGH in consequence of his new and more important appointment in the University of Pennsylvania*, Professor of the Theory and Practice of Medicine, in the room of the te Dr. Benjamin Rush. |
