reference. 1 am indebted to him, likewise, for his permission to 

 allow Babu Prasaima Kum*r Sen, Overseer of the Royal Botanic 

 Gardens, to assist me in my enquiries, and this has enabled me 

 to solve many a donbtful point in the translation of the scientific 

 names of plants into the vernaouJar. Daring the absence of 

 Dr. King from the Gardens, Mr. S. Kurz cordially helped me 

 whenever I had occasion to seek his aid in identifying native 



medicines. 



Dr. Norman Chevers kindly corrected f j>r me some of the 

 forms, and put me in ihe proper way of doing this work. Rai 

 Kauai Lai Day Bahadur has, at considerable sacrifice of hia 

 valuable time, analyzed the mineral substances "and preparations, 

 the chemical composition of which has been described in the first 

 part of this work. Most of these preparations have now for the 

 first time been analyzed by him. To Dr. Rajendralala Mitra, 

 I am indebted for valuable advice regarding the plan of getting 

 up this work, and for explanations of some obscure questions 

 regarding the history of of Indian medical works. 



To Kaviraj Binod Lai Sen, my grateful acknowledgments are 

 due for the very liberal manner in which he has furnished me 

 with lists of medieines generally used in practice, supplied me 

 with specimens of native medicines, and practically shewn and 

 explained to me the processes by which metallic medicines are 

 prepared in the dispensary under his charge. His cordial assis- 

 tance has enabled me to bring out this work with greater 

 confidence than if I had had to depend upon my knowledge of 

 Sanskrit books alone. 



Kaviraj Brojendra Kumar Sen Gupta, Eon of the late learned 

 Hiiiadban Sen Gupta, the leaiing native physician of his time in 

 Calcutta, and latterly physician to his Highness the Maharaja of 

 Kashmere, has interpreted for me the meanings of many obscure 

 passages in Sanskrit, furnished me with specimens of drugs from 

 his dispensary, supplied me with a list of the preparations ordi- 

 narily used by him in prwtice, and cordially rendered me such 

 other assistance as I had oocasion to seek from him.
