are identical with the micrococci of human pneumonia. And 

 they further assert that artificial cultures of the micrococci 

 derived either from human pneumonia or from pleuro- 

 pneumonia'of cattle, produce in cattle the typical pleuro- 

 pneumonia. From my own observations I have reason to 

 doubt the accuracy of these statements. 



5. Micrococcus gonorrhoea. Micrococci have been found 

 in the pus of gonorrhoea. Neisser, 1 and later Bokai and 

 Finkelstein, 2 described them as spherical organisms of about

o f oo8 mm. diameter, generally forming dumb-bells, or sarcina- 

 like colonies of four. Several such groups form a zooglcea. 

 They adhere to the pus-corpuscles and epithelial cells. They 

 stain easily and well in methyl violet and gentian violet. 

 Bockhart 3 has succeeded in artificially cultivating these 

 micrococci, and in producing with them the disease by
