PREFACE. 1X 
Kippist, the librarian of the Linnean Society, his thanks 
are especially due, for the kind and efficient aid he has 
given towards the necessary investigations. 
In committing his work to the press, the Author is 
sensible that he has to ask indulgence for frequent errors 
and omissions, arising from the many interruptions and 
conflicting interests of an arduous profession, and which 
he hopes will be admitted in his excuse. He has aimed, 
with what degree of success others can best determine, to 
introduce to the public, and especially the professional 
mind, his views on this most interesting and instructive 
subject, in connection with the study of homceopathy ; 
while he is very diffident as to his capabilities of doing 
justice to the theme. 
The Author is anxious to attract the attention of every 
philosophical inquirer after Science and Truth, who will 
discover in the pursuit of this branch of study unbounded 
suggestiveness, and ever-expanding views of Creative Wis- 
dom, which has thus concealed in the unassuming and 
often unattractive forms of the plants beneath our feet, 
many of its divinest secrets. These can be developed only 
by patient and laborious research. et us then continue, 
with unabated ardour, to penetrate more and more deeply 
into the beneficent arcana of Nature. The reward is cer- 
tain; for what consciousness can be so gratifying as that 
of success, in adding to our treasury new means of en- 
countering the Demon of Disease, and bringing back the 
Angel of Health?
