EVOLUTION AGAINST DISEASE

numerous that volumes might be filled with them, that tend 

 to show that the evolution has been considerable. Thus we 

 read that, owing to malaria and dysentery Muscat is unin- 

 habitable by Europeans during the summer months ; l that 

 in the districts infested by yellow fever strangers are vastly 

 more liable to attack than natives ; 2 that in Ceylon the 

 mortality from dysentery among the troops reached the rate 

 of 230 per 1,000 ; 3 and so forth. The following table 

 extracted from the official Report on Sanitary Measures in 

 India in 1892-3, exhibits the difference between the 

 European and native troops in relation to the sum-total of 

 the diseases prevalent in that country. In contrasting the 

 two races it should, however, be borne in mind, that, while 

 the whites, on the one hand, since they are mostly unmarried, 

 suffer more from the venereal diseases than the natives, 

 whereby their sick and death-rates are unduly raised, the 

 natives, on the other hand, are more exposed to infection by 

 other diseases. It should be noted, also, that many of the 

 whites who were invalided home would have died had they 

 remained in India, and, therefore, that the total death-rate 

 of the Europeans should be calculated rather on the basis of 

 " total loss " than of " deaths " when comparing it to the 

 " mortality including absent deaths " of the natives.
