PREFACE xi 



Messrs. Burrows, Wellcome & Co., of London, placed at 

 my disposal three of their excellent medicinal travelling- 

 cases. 



I want to express my appreciation of many services 

 rendered by the Nederlandsche Handel-Maatschappij 

 and its branches, especially the Factorij in Batavia. I 

 am under similar obligations to the Koninklijke Paket- 

 vaart-Maatschappij, and my thanks are also due to 

 De Scheepsagentuur for courtesies received. Miss Ethel 

 Newcomb, of New York, has kindly transcribed the two 

 songs rendered. 



Finally I desire to make grateful acknowledgment of 

 valuable assistance rendered by Doctor J. C. Konings- 

 berger, and by Doctor W. van Bemmelen, director of 

 Koninklijk Magnetisch en Meteorologisch Observator- 

 ium, Weltevreden, Batavia. 



Although force of circumstances altered the scope and 

 to some extent the character of this expedition, never- 

 theless my Bornean experiences afforded great satis- 

 faction. Moreover, my sojourn in the equatorial regions 

 of the East has imbued me with an even stronger desire 

 to carry out my original purpose, which I hope to ac- 

 complish in the near future.
