where these diseases are not reported, it will be necessary to get 

 the figures from other sources. In this case, a beginning should 

 be made as far in advance of the date of opening of the campaign 

 as possible. 



In an anti-malaria compaign with which the writer was 

 connected in 1920, no figures as to the incidence of malaria, were 

 available from official sources. It was, therefore, necessary to 

 get some figures from the physicians of the community as to the 

 incidence of the disease during the preceding 2 years. 



Owing to the difficulty, in cases where the illness was pro- 

 longed, of determining whether the patient was suffering from 

 one original infection or successive ones, it was considered 

 preferable to obtain from the physicians figures as to their calls 

 and consultations for malaria rather than as to cases. 



Accordingly, each physician of the community was called on, 

 the situation explained to him and a blank left with him, to be 

 filled out promptly with data covering his malaria practice for 

 1918 and 1919 and returned to the director of the campaign. 

 The blank form is reproduced below.
