each furnished \vith an obtuse process. These 

 germs were also met with in a free condition, and 

 their development was traced up to a certain point, 

 after which Busch was obliged to discontinue his 

 investigations. 



In the same situations as Noctiluca, Busch further 

 discovered numerous transparent gelatinous bodies, 

 of similar size and appearance, and possessino^, in 

 many cases, phosphorescent properties, though not 

 pro\ided with radiating fibres, or locomotive ap- 

 pendage. These bodies were almost destitute of 

 structure, but on a portion of their surface there 

 usually occurred several remarkable yellowish pro- 

 cesses, either rounded or tapering to a point, con- 

 taining in their interior minute spherical granules. 

 The nature of these problematical organisms pre- 

 sents a subject for future inquiry.
