MICROCOCCUS OF PHOSPHORESCENCE. 
The phosphorescence of the sea is due to the presence 
of Noctiluce, protozoaria of the group of Flagellata, which 
come to the surface in stormy weather. 
Many other 
marine animals present the same phenomenon. The 
phosphorescence of rotten fish is due to the presence of 
a special micrococeus which forms large circular zoogloem, 
The same micrococcus also appears on putrefied meat 
and imparts to it a phosphorescent light.
