A Text-Book of Botany

The first edition of the English translation of this text-book was the work of Dr. H. C. Porter, Assistant Instructor of Botany, University of Pennsylvania. The proofs of this edition were revised by Professor Seward, M.A., F.R.S. The second English edition was based upon Dr. Porter's translation, which was revised with the fifth German edition. The present edition has been similarly revised throughout with the eighth German edition. Such extensive changes, including the substitution of a completely new section on phanerogamia, have however been made in the latter that it seemed advisable to give in outline the history of the English translation instead of retaining Dr. Porter's name on the title page. The official plants mentioned under the Natural Orders are those of the British Pharmacopoeia instead of those official in Germany, Switzerland and Austria, which are given in the original. In making this alternation I have consulted Materia Medica and Therapeutics, by J. Mitchell Bruce, M.A., LL.D., M.D.
