ful passages. Additional help has also been derived from a com-
parison of several extracts from Rasárnava with which Rasendra-
chintímani, Rasaratnasamuchchaya, Sarvadarsanasamgraha.,
Yogatarangini etc. abound. In spite of all these collateral ad-
vantages there was much that could be desired. While the
third and concluding part of the present work was in the press,
I received a letter from Kaviráj Durgánáráyan Sen Sástrí, who
had been to Jammù on a professional visit, volunteering his servi-
ces for the search of rare Sanskrit MSS. bearing upon Chemistry
and Medicine. Among the several MSS. which the scholarly
instinct of the Kaviráj had hit upon was one entitled Rasakáma-
dhenu. Although this work is merely a compilation, it proved
to me like a God-send, as it is full of lengthy extracts from
Rasárnava of remarkable textual accuracy. Indeed, so material
has been the help rendered by Rasakámadhenu that it has been
thought advisable to draw up a list of corrections based upon
this work and it has been inserted as an appendix.
As the Preface appears over my signature alone, I avail
myself of this opportunity of expressing my deep obligations to
my collaborator, Pandit Harischandra Kaviratna, on whom has
mainly devolved the vast labour of going carefully and critically
through the text of the MSS. He has also drawn up the exhaus-
tive table of contents (अनुक्रमणिका) and the alphabetical index
with glossary of technical terms. It is to be hoped that even a
casual reader will have no difficulty in finding out the parti-
cular information he is in need of.
