PKEFATOKY NOTE 



THE original * authors of this text-book as it appeared in 1894 

 were Professors Eduard Strasburger, Fritz Noll, Heinrich Schenck, 

 and A. F. W. Schimper. The death of Professor Strasburger 

 since the last English edition was published renders it inaccurate 

 to give his name as an author of the work. His position as the 

 original founder of the text-book requires to be recorded and is 

 therefore indicated by the name Strasburger's Text-Book, which 

 has been in current use in this country. In the present edition 

 the division on Morphology is by Professor Fitting, that on 

 Physiology by Professor Jost, that on Thallophyta, Bryophyta, 

 and Pteridophyta by Professor Schenck, and that on Spermato- 

 phyta by Professor Karsten. Their names are therefore given as 

 the authors on the title-page. 



The first edition of the English translation was the work of 

 Dr. H. C. Porter, Assistant Instructor of Botany, University of 

 Pennsylvania. The proofs of this edition were revised by Pro- 

 fessor Seward, M.A., F.E.S. The second English edition was 

 based upon Dr. Porter's translation, which was revised with the 

 fifth German edition. The third English edition was revised 

 with the eighth German edition, and the fourth English edition 

 with the tenth German edition. The present edition has been 

 similarly revised throughout with the fourteenth German edition. 

 Such extensive changes, including the" substitution of completely 

 new sections on Morphology, Physiology, and Spermatophyta, 

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

 that it seems advisable to give in outline the history of the 



4812.
