Hongkong (1902), 37.3 per cent mortality. 

 ■ British New Guinea: 



1902, 22.80 per cent mortality. 



1903, 26.6 per cent mortality. 

 Egypt, 70 per cent mortality. (7) 



b. Cases treated with serum: 



Bahr (Fiji Inland), 106 cases, 1.8 per cent mortality. (1) 



Sandwith (England), 9 per cent mortality. (6) 



Shiga (Japan), 9 per cent mortality. (4) 



Willmore (Egypt) (1912-1913), 12 per cent mortality. (7) 



My cases 20 (1 death), 5 per cent mortality. 



In the above figures there is seen a considerable difference in 

 mortality between the two methods of treatment. Undoubtedly 

 the serum has done a great deal toward reducing the death 

 rate. 



While my investigations along this line have barely started, 

 and my opportunities have so far been limited, I abstain from 

 drawing definite conclusions for the present, although it cannot 

 be doubted that the value of the specific treatment is strongly 

 indicated as shown in the results hitherto attained. I hope, 

 however, to carry out this work on a larger scale when ample 

 opportunities are presented to me, from which definite conclu- 

 sions may be drawn. 



In conclusion I wish to express my obligations to Professor 

 Ariston Bautista, chief of the Department of Medicine, for allow- 

 ing me to carry out this work in his department; to Doctors 

 Guerrero, Sison, Domingo, and Gutierrez for valuable suggestions 

 during the course of treatment, and to Doctors Esquivel, Ba- 

 nuelos, Hilario, Baltazar, and Concepcion for their cooperation. 

 I am especially indebted to Dr. Otto Schobl, of the Bureau of 

 Science, who furnished me the serum and who made several 

 bacteriological examinations of the stools for me. Also I have 

 to thank him for his kindness in translating the German 

 literature.
