also facultatively anaerobic. Some are able to resist a pressure amount- 
ing to 100 atmospheres. Some form pigments ; a larger number are 
luminous in the dark ; some of the latter are pathogenic to mice and 
guinea- pigs. The luminous forms were most commonly met with on the 
surface of living fish. There can be no question that marine bacteria are 
as important as the terrestial forms in bringing about decomposition ; but 
no evidence w r as obtained that they are pathogenic to marine animals, 
though it is most probable that they are so.
