PREFACE vii 



in those collected by myself. My opinion/ whatever its 

 value, is derived more from his facts than my own. If 

 I have misrepresented any of his facts to suit my own 

 opinions, I have done so unintentionally and I offer my 

 sincere apology. 



The frontispiece is the work of Mr. B. L. Das. The 

 figure on the left is of a dead rat lying upon its side, and is 

 very true to nature. Of the others, one is from a stuffed 

 specimen and the other from an animal living in a cage, 

 consequently, these two have a less natural appearance, 

 but in all the colour is a true representation. The other 

 drawings are mostly traced from photographs which 

 have already appeared in the publications of the Indian 

 Museum. (Rec. Vol. III. Pt. I., Mem. Vol. II. No. I.) 



The map of Poona was kindly provided by Captain 

 Kundart, I.M.S., to whom I am otherwise much indebted. 



I must also express my warmest thanks to Captain 

 G. I. Davys, I.M.S., and to many other friends, for the 

 most part my fellow-workers in the Indian Medical Service, 

 for much help and hospitality during the progress of the 

 investigations which form the chief subject of the book.
