PREFACE TO THE FIRST EDITION. ix 
works ; but he trusts, at the same time, that it will be found to 
contain everything which the student of Botany really requires, 
whether he is pursuing it as a branch of professional or general 
education, or for pleasure and recreation. 
The vast number of facts, observations, and terms necessarily 
treated of, in the departments of Structural, Morphological, and 
Systematic Botany, have compelled the author to give but a brief 
account of the Physiology of Plants ; he hopes, however, that, 
even here, all the more important subjects bearing upon the 
education of the :nedical practitioner and pharmacist will be 
found sufficiently comprehensive. Those who require a more 
complete knowiedze of this department, he would refer to the 
Second Part «f Balfour’s ‘ Class-Book of Botany,’ in which 
valuable work full details upon Physiological Botany will be 
found. 
The author had a great desire, also, to include in the present 
volume an Appendix upon Descriptive Botany, and a Glossary 
of Botanical Terms ; but the Manual having already exceeded 
the limits desired, he is unable to do so. The Index itself will, 
however, serve as a glossary by referring to the pages in which 
the different terms are defined and explained ; and with regard 
to Descriptive Botany, the author would especially recommend 
every reader of this work to obtain a small but very valuable 
work on that subject which has been recently published by Dr. 
Lindley. 
In compiling this volume the author has been necessarily 
compelled to refer to many works and original memoirs on 
botanical science, and he hopes that in all cases he has given 
full credit to the different authors for the assistance they have 
afforded him. If he has omitted to do so in any instance, it has 
arisen from inadvertence, and not from design. To the valuable 
works of Mohl, Jussieu, Schleiden, Mulder, Hofmeister, Asa 
Gray, and Schacht, among foreign botanists; and to those of 
Lindley, Balfour, Henfrey, Hooker, Berkeley, Pereira, and 
Royle, among British botanists, he begs to express his obligations. 
To his friend, Daniel Hanbury, he is also indebted for much 
valuable information communicated during the progress of the 
work. To Lindley’s ‘ Vegetable Kingdom,’ Pereira’s ‘ Materia 
Medica,’ and to the many valuable articles upon the Anatomy of 
Plants in Griffith and Henfrey’s ‘ Micrographic Dictionary ’ by 
the lamented Henfrey, the author is more especially indebted.
