22, 2 Mendelson: Resistance of Siamese to Disease 123 



2. Although resistance to certain diseases, such as cholera and 

 plague, cannot be demonstrated by specific blood reactions, it 

 is present in the form of a marked resistance to germ infections 

 as a whole, that is, "general infection immunity." 



3. The nervous system of Orientals is much more resistant to 

 the effects of germ infection than is the nervous system of 

 Occidentals. 



4. The natural immunity to infection and resistance to disease, 

 as exhibited by the Oriental, is of real value to the health officer 

 working in the East under present conditions.
