In hospitals many patients are admitted moribund and histories are 
difficult to obtain and unreliable, errors are necessarily more frequent. In 
many cases the patient is suffering from two or more serious diseases so 
that a large personal equation enters into determination of the cause of death. 
It can, however, be definitely stated that in some districts the case 
mortality is constantly high and in others consistently low. 
In the district hospital returns Kwala Lumpur the mortality amongst 
those from the town and immediate neighbourhood was 53 or 16.9 per cent. 
In those examined after death nearly one half were found to be suffer¬ 
ing from other serious disease, particularly from Dysentery, and, therefore, 
the figures from that district give too high a rate for uncomplicated 
Beri-Beri. 
Three districts may be fairly contrasted to show the variation in case 
mortality in different places. It will be noted that the case mortality has 
no definite relation to the number of admissions :—

The first of these districts is largely an agricultural one, but out of the 
last 144 cases, 139 were miners, 3 had no occupation, and only 2 were 
gardeners, though the miners alone would employ over 500 gardeners. So^ 
that here also the incidence is mainly on the miners. In the two largest 
mining areas in this district Kajang and Semenyih the rates were 24 and
