XXlll 



editor of the Natur eland, has laid me under 

 a deep obligation by contributing a fore- 

 word to this volume. I owe a deep debt 

 of gratitude to Professor Bipin Behari 

 Gupta, M.A., for his valuable suggestions, 

 and to my cousin Dr. Narendra Nath 

 Law, M.A., B.L., P.R.S., P.H.D., whose words 

 have always served as a stimulus to my 

 energy, and whose efforts have always 

 been directed to the prefection of the 

 results of my labours. Dr. Law has put 

 me under a fresh obligation by including 

 this volume in his Calcutta Oriental Series. 

 My thanks are due to Mr. Sudhindra 

 Lai Roy, m.a., for material assistance and 

 to Mr. N. Kushari for the artistic drawing 

 of the illustrations. I must also acknow- 

 ledge the help I have received from 

 Messrs. Nalin Chandra Paul and Raghu 

 Nath Sil while putting the manuscripts 

 through the press.
