THE MICROBES OF HUMAN DISEASES. 231 



The same micrococcus, or, at any rate, a microbe 

 which cannot be distinguished from it, is often found 

 in the purulent ophthalmia of new-born in,fants. It 

 is difficult to admit, even when we make allowance 

 for the great susceptibility of an infant's eyes at the 

 moment of birth, that such ophthalmia is always of 

 gonorrhceal origin. However this may be, the 

 micrococci of purulent ophthalmia resemble those of

 siderably reduced the intensity of this disease. 



The red, malodorous sweat of the armpits is due

 the sweat, or massed in the form of a zoogloea, and 

 adherent to the hair of the skin. The red colour is 

 not due to iron, for no trace of this metal is revealed 

 by analysis ; it approximates in its nature to that of 

 Micrococcus frodigiosus. It may be cultivated in
