viii PREFACE. 



" schedules " at a small cost, but the necessary 

 form may be easily drawn with pen or pencil by 

 the student himself. I strongly recommend their 

 use, both by private students and in colleges and 

 schools. 



Most of the excellent woodcuts employed in this 

 work were drawn by Professor Henslow's daughter, 

 Mrs. Barnard, of Cheltenham, from the admirable 

 Sheet Diagrams designed by Professor Henslow, and 

 executed by Mr. Fitch, for the Committee of Council 

 on Education. They have been liberally placed at 

 the disposal of the publishers by the Rev. George 

 Henslow.

In the present edition I have been allowed to 

 make some little alterations, chiefly in the chapter 

 on minute structure and vital processes. To students 

 trained in the newer school of Botany, these must, 

 no doubt, seem inadequate, but regarding this as a 

 First Book, specially intended for use in schools 

 and for young people taking up Botany remote from 

 class-room and laboratory, I think it better not to 

 alter materially the relative proportions hitherto 

 assigned in it to the different sections of general 

 morphology, anatomy, function and classificatory 



matter.
