 and sometimes in the form of a circlet. Althoup-h 

 Dr. Pringsheim was disposed to look upon these bodies 

 as anomalous propagative spores belonging to the plant 

 itself^ and destined to reproduce it^ he came to such 

 a view principally because of his certainty as to their 

 mode of origin. He says :~^ That they are foreign 

 structures^ not belonging to the Spirogyr^^ would be an 

 altogether inadmissible hypothesis^ since they are formed 

 In the interior of the closed f lament cells of the Spirogyr^^ 

 directly from their contents^ Dr. Pringsheim had seen 

 bodies originating after a similar fashion within the 

 resting spore of

and as he had not seen the further developmental modi- 

 fications of these newly-produced organisms, the view 

 which he adopted seemed the only one open to him at 

 the time. Now, however, there cannot be much doubt 

 as to the relationship which exists between these bodies
