PREFACE TO THE ENGLISH 

 EDITION. 



THIS translation of Professor De Bary's ' Vorlesungen iiber 

 Bacterien' has been prepared because there is at present 

 no book in English which gives in like manner ' a general 

 view of the subject ' of Bacteria, and ' sets forth the known 

 facts in the life of Bacteria in their connection with those 

 with which we are acquainted in other branches of natural 

 history.'
