and Chemical Research, Tokyo, Prof. H. K. Sen of the Calcutta University, Mr. Arthur Edward Wait, Prof. L. M. Dennis of the Cornell University, Prof. A. B. Lamb of the Harvard University, and many other well-known scholars, who have encouraged me by their sympathetic appreciation of my ambitious work.

I am also indebted to Pandit Nritya Gopal Panchatirtha, and to Professors Kshitish Ch. Chatterjee M. A. and Satkari Mookerji M. A. of the Deptt. of Sanskrit, Calcutta University, not only for the help they rendered to me in correcting the proof sheets but also for several suggestions received from them. The encouragement which I have received from the following members of the Institute of Hindu Chemistry also deserves mention:—Prof. Ramnarain Kayasth M. Sc. B. Ag. of the Nagpur University, Messrs. Girija Nath Mookerji B. Sc., Asstt. Analyst, Calcutta Corporation, Anindra Nath Chatterji, Sarojnath Bagchi, Ganapati Chakavarty M. A. and Upendra Nath Dutt (who has taken the trouble of compiling the Appendix to the present volume).
