Pig. 1 shows certain bodies found in the cells of a Sphagnum 

 occurring in the same pool [and often on the same plants, -which har- 

 bour undoubted examples of this organism (as sho^wn in next figure),] 

 and which are supposed to have some genetic relationship. 



Fig. 2. — A portion of a leaf of Sphagnum showing young Chlarny- 

 domyxa examples ; to the left are seen green ones, neax the bottom two 

 very small, still globular, towards the middle a few now red, owing to 

 the abundance of the red granules ; the larger examples have put- on a 

 torulose figure, owing to the constriction caused by the recurring cinc- 

 tiu'e of the annular fibre of the Sphagnum-cell. Towards the right is 

 seen a CMamydomyxa extruded, and still attached by a neck-like por- 

 tion of the wall ; the contents have become re-encysted now outside 

 the Sphagnum-cell. 



Fig. 3. — A condition rarely met with, showing the inner sarcodic 

 substance subdiyided in a number of nearly equal-sized globular por- 

 tions, the sub-contents reddish inclining to orange, and each indi-\-i- 

 (lual ball encysted in its proper wall ; the whole within the outer 

 many-layered original envelope. 



Fig. 4. — The many-layered envelope of an example after severe 

 pressure, the most of the substance removed, a few colouring granules 

 only being left. 



Fig. 5. — A small example after being boiled in caustic potash. 



Fig. 6. — Portion of an example treated with iodine and sulphuric 

 acid.
