Fig. I. Chart showing the incidence of the disease as compared with the existing 

 male population. 

 II. Chart showing incidence of the disease as compared with the existing 

 female population. Both charts show that a larger percentage of both 

 sexes under ten years of age were affected. Between ten and nineteen 

 years of age the number of cases of both sexes diminished. In the 

 third decade, while the number of eases of males and females is 

 practically the same, the available number of females is less. 



III. Chart showing the percentage of total mortality by the two methods of 



treatment. The figures demonstrate that the intravenous method is 

 the superior form of treatment for all ages, but its value was less 

 apparent for cases from 20 to 29 and over 60 years of age. 



IV. Chart showing the result of the two methods of treatment in collapse. 



The intravenous is shown to be the better for all- ages, but its value is 

 least apparent in the patients under 10 and over 60 years of age. 

 V. (In the text.) Apparatus for injecting normal saline solution. 

 VI. Chart showing the number of cases of uraemia after treatment by the 

 intravenous method and the resulting mortality. Treatment was most 

 effective between the ages of 20 to 29 and 40 to 49 years.
