PREFATORY NOTE 



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 tenth German edition. Such extensive changes, including the 

 substitution of completely new sections on Physiology and Phanerogamia, have 

 however been made in the work since it was first translated, and in the third and 

 fourth English editions, that it seems advisable to give in outline the history of the 

 English translation instead of retaining Dr. Porter's name on the title-page. 



"rhe 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. . . . 



PRESS NOTICES OF FORMER EDITIONS 



" The translator has been most successful in his work, the book reading as though 

 originally written in English. . . . One of the best, if not the best, text-book ex- 

 tant." — Nature. 



"The whole style of the book is admirable; the type, illustrations, and general 

 arrangement leave nothing to be desired, while the coloured pictures of typical 

 cryptogams and phanerogams, which are scattered throughout the text, are life-like 

 in their beauty. . . . We have not the slightest doubt that this text-book will be 

 long regarded as a standard work, and we wish it all the popularity it deserves." — 

 Knowledge. 



"It would be not doing justice to the present book if we did not place it in the 

 foremost rank. . . . We may cordially commend the book as one worthy to take a 

 place on the shelves of the expert and on the work-table of the student." — Alhenaum. 



"This work includes the most essential knowledge of several special books, it is 

 almost a library in itself, and is moreover, a g;uide to botanical literature. It is well 

 worth its price, and should be looked upon as a necessary possession." — Gasrden.
