BACTERIA, '.'.) 



JPfeifcii Bound colonies, cup-shaped depression*, the solid 

 gefe:ine that remain* becoming colored with greenish-yellow

Phosphorescent Bacteria, Six varieties of pbo*pborescent 

 bacteria bare been described ; they are found usually in sea- 

 water, or upon objects tiring in the sea. 



Bacillus PhosphoTescens liodifiii, (Piscber,) 



Oriyin. Tropical waters, 



Jfcrm. Thick rods, with rounded ends, sometimes forming 

 long thread*, 



Froperffe*, < Very motile ; liquefying gelatine at a tempera- 

 ture of %P to arp C, with oxygen and a little moisture, and in 

 the dark, a peculiar electric-Mae light derelops a pbospbores- 





Grotctk Slowly ; must bare oxygen ; does not grow under 

 HPC, ororerSCPC, 



Plata. Little round, gray points, which under low power 

 appear as green colonies with reddish tinge around them. 

 Cooktdjbh, when smeared upon the surface with a little of the 

 culture, show the phosphorescence most marked. Grows well 

 oa potatoes and bhod-tentm, 



BacmwPhosphoresceiiiliidi^fniu. (Fischer,) 



Origm. Waters in the northern part of Germany. It diflers 

 from the Indian bacillus, in that it grows at a temperature of 

 5P <X, and does not develop upon potatoes or blood-serum, 



Bacillus Phosphorescens Geliduj. < FtoteK ) 



Ort^m. Surfeces of salt-water fish, 



Jbrm, Short, thick rods, looking oral sometimes ; zoogkea 

 are often formed* 



Propertit*. Motile ; does not liquefy gelatine; a beautiful 

 phosphorescence from the surface of fish; it can be photographed 

 by its own light, 



Colonies. Grows best between CP and 2fiP C, ; grows slowly, 

 and mostly on the surface. The material must contain salt, 

 A bouillon made with sea-water, or 3 to 4 per cent.
