‘APPENDIX. D. 
-REFERENCE BOOKS.! 
‘Only a few of the books which the author regards as the most’ 
useful guides to elementary study and research in their several 
departments are here named. Both pupil and teacher will find it 
desirable to consult some of them frequently throughout the whole 
course of the botanical work. The starred titles (**) indicate books 
which will aid the teacher, but which the ordinary high-school pupil 
could hardly use. Where it is possible to discriminate, the best 
book, that is the book which combines accuracy, fullness, newness, 
and simplicity of statement to the highest degree, is placed first in 
its own list.

The Kerner and Oliver is a costly book, but is almost indispens- 
able, since it goes over the greater part of the field of botany in a 
full and accurate, yet thoroughly simple and interesting way. The 
only criticism that can be urged against it is on the score of 
occasional fanciful statements, in regard to theories as yet unproved. 
The work by Strasburger and others is perhaps the best recent 
' 1 The author has been much aided in the preparation of this list by the one con- 
tained in Spalding’s Introduction to Botany. 
' 2 A translation of this book will be issued by Macmillan & Co. The author has 
been obliged in the present book to refer to the first German edition of the Lehrbuch, 
since the second edition has not reached him in season to be cited.
