presented a similar appearance to that of the Monads. 

 There were also several unjointed Bacteria^ presenting 



r 



most rapid progressive movements, accompanied by 

 rapid axial rotations j many Torula-ctWs of different 

 kinds, and coarser fungus spores, some of them with 

 segmented protoplasmic contents; and lastly, some 

 mycelial or algoid filaments, containing tolerably equal 

 blocks of colourless protoplasm within an investing 

 sheath. 



^ A drop containing several of the Monads was placed for about five 

 minutes on a glass slip, in a warm-water oven maintained at a tempera- 

 ture of 140^. All the movements of the Monads ceased from that 

 'time ; and they never again showed any signs of life.
