vili] MICROCOCCI i6i 



was no gangrene here ; but cedema was present, spreading 

 from the seat of the inoculation. Sub-serous haemorrhages 

 appeared in the intestines ; and minute haemorrhages were 

 also present in the oedematous tissue and in the muscles of 

 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, in dumb-bells, and in 

 zoogloea. The micrococci measured about o-8 to i yu, 

 in their long diameter. These micrococci (taken with 

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

 same fatal disease. 



i6. Micrococcus bombycis (Microzyma bombycis, B^champ). 

 — Oval micrococci, of about i'5 /a in 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 corpuscules," " 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, o'oo3 

 to o'oo4 mm. long, o 002 mm. broad; they are very bright 

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



17. Micrococcus of gonorrhixa {gonococcxis). Neisser was 

 the first who pointed out the constant presence, in the 

 exudation in gonorrhoea, of peculiar micrococci, which 

 occur as dumb-bells and as masses of dumb-bells, either
