86 MICRO-ORGANISMS AND DISEASE. [CHAP. 



the thigh and abdomen. The oedematous fluid, the cuta- 

 neous veins, the capillaries in the kidney, especially those 

 of the glomeruli, in the lung, and in the spleen, contained 

 numerous oval micrococci, singly, as dumb-bells, and in 

 zoogloea. The micrococci measured about croooS to 0*001 

 mm. in their long diameter. These micrococci (taken with 

 the blood) produced in another rabbit and in a mouse the 

 same fatal disease. 



14. Micrococcus bombycis (Microzyma bombycis, Bechamp). 

 Oval micrococci, of about 0*0015 mm - m length, present 

 in large numbers, singly, and as dumb-bells and chains

(straight or curved), in the contents of the alimentary canal 

 and in the gastric fluid of silkworms dead of the " maladie 

 de mortsblancs, flacherie" Micrococcus ovatus, Nosema 

 bombycis. Present in large numbers in the blood and 

 organs, ova included, of silkworms affected with the disease 

 called " maladie des corpuscles," "pe'brine," or Cornalia's 

 disease. Cornalia first saw them, afterwards Lebert and 

 Nageli. Pasteur proved definitely that ingestion as well as 

 inoculation of the silkworms with the micrococci produces 

 the disease. The micrococci are comparatively large, 0*003 

 to 0*004 mm. long, 0*002 mm. broad; they are very bright 

 and occur singly, or in dumb-bells, or in small groups.
