3. Some of the secondary capsules. 



4. Secondary capsule, viewed as an opaque object 



5. The same as a transparent object. J. 



6. Part of paries, shewing the tendency of component cells to 

 separate. 



7. Contents. 



8. The same under pressure : it is scarcely cellular, is grumoua- 

 looking, very opaque, contains imbedded in it, larger cells ? or 

 cavities perhaps, and trifacial cells of which one has escaped* 

 They are to be recognised wlien contained, by their colour and 

 more defined outline. 



Salvixia verticillata, PI. CXXV. {Continued.) 



Fig. I., — 1. Represents the youngest of a set of the oblong bo- 

 dies. The yellow sac of the largest was complete, though 

 still young, and only yellowish. It shews no central sac, no 

 trifacial cells, but a continuous mass of grume, shewing a 

 tendency above to develope cells. In this grume nothing was 

 seen except numerous irregular angular nuclei, without a mem- 

 brane. J. 



2. Grume and nuclei. 1-16. 



3. Represents the very young state of the sphrerical pedicellate 

 bodies : shewing I fancy, the commencement of the cavity in 

 which grume is subsequently deposited. Generally in proportion 

 as the cellular membrane is more distinct, the nuclei are less so, 



4. Grumous nuclei from an abortive oblong body, all of the same 

 had aborted, only in one instance were there one or two tri- 

 facial cells ? The abortion has occurred at a period the same 

 as No. 1,-1-16. 



5. Nuclei of a more advanced stage, and developing, trifacial 

 cells existed towards the circumference, though not many, and 



the central cell existed. The first change after enlargement is 

 the appearance of a cavity in the centre. 



6. Two ovula, J, — the grume is not resolvable under 1-16, the 

 two cells represented are probably accidental, the large one at 

 the base is of the foramen. 



7. Smaller ovulum, under pressure, grumous matter filling the 

 space between the anuulus and base of the nucleus.
