PREFACE. 



ALTHOUGH entitled " Oranges and Lemons," this work 

 treats of all the varieties of Citrus. 



I originally commenced it with a commercial object, 

 that is, to show the numerous varieties of oranges, 

 lemons, &c., now to be found in India, and their 

 economic value. If not for export, at least there is 

 room for an extended internal trade in these fruits, 

 and for the development of certain industries from 

 them in India. Besides the fresh fruit, the preserves 

 made from it might be largely supplied in India in- 

 stead of importing them. Then, essential oils and 

 citric acid might, in due course, be also manufactured. 

 The fact, however, was that the more researches I 

 made, the more interesting the whole subject became, 

 and as I found that not much of a satisfactory nature 

 had been recorded regarding the cultivated citrus of 

 India, I was tempted to extend my researches by ask- 

 ing friends to send me samples of citrus from various 

 parts, which I had not any opportunity of visiting. I 

 take this occasion to cordially thank all those who have 

 helped me with specimens, drawings, books, and by 

 their correspondence, and with statistics of trade in 

 India connected with oranges and lemons. In the 

 course of these investigations, one thing led to another, 

 facts led to this and that speculation, and the present 

 work, whatever may be its worth, has been the result.
