QUINOLOGY 
OP THE 
EAST INDIAN PLANTATIONS. 
PART I. 
CHEMICAL AM) MICROSCOPICAL INVESTIGATIONS. 
Introductory Remarks. 
The chemical and microscopical investigations contained in the present Part are strictly in continuation of 
the kindred researches in my previous works, and, although by no means complete or exhaustive, may 
afford some practical assistance in the great and beneficent undertaking of the naturalization of the Quinine- 
producing trees in India. 
I defer for the present any detailed remarks on the botanical aspects of the varied species of Cinchona* 
now under cultivation, the more especially as I am informed by J. Broughton, Esq., the Quinologist 
appointed by Government to the chemical oversight of the plantations at Ootacamund, that he has instituted 
and is carrying forward varied observations on the influence of soil and climate, and especially of elevation 
above the sea-level, on these plants, the results of which will doubtless present many novel and most 
important facts confirmatory or otherwise of views here advanced by me. The Indian Government has 
been fortunate in the choice of servants to whom the practical carrying out of the details of this great 
scheme has been confided, and I am glad to think that in this most recent instance they have been equally 
successful. It is not for me to award the meed of praise to those whose toils and dangers in the service 
entitle them to the gratitude of the world; but it may he permitted me, as having previously given 
what assistance I could render in the analysis of the specimens sent home from various parts of India, to 
hear my unbiassed testimony to Mr. Broughton’s skill and diligence, as evidenced by what he has already 
accomplished in a peculiarly difficult line of chemical investigation. 
Elevation above the Sea-Level. 
Recent observations on this point may save the apparently useless attempt to cultivate these plants at 
a level below 4000 feet above the ocean ; I refer for the full elucidation of the subject to the results of 
Mr. Broughton’s observations, which I hope to see published. 
* I adhere to the old Linnean term, but quote from my correspondents as I find the word spelt by them.
