PREFACE TO THE ENGLISH EDITION 



THE teaching of Plant Physiology in England, which owes so 

 much to the energy and enthusiasm of Francis Darwin, has been 

 seriously retarded by the want of suitable manuals of laboratory 

 practice, and hence no apology is needed for the appearance of 

 a translation of Professor Detmer's well-known and excellent 

 Praktikum, 



No sufficient reason has been found for addition or alteration, 

 and the Second German Edition has been presented in its 

 entirety.
