Chara The globules of Chara contain filaments which with a low power 
of the microscope appear transversely undulated. With a plano-convex lens of 
very high power, I have observed that the filaments consists of transparent 
tubes, containing in their interior numerous oval, and in some cases irregularly- 
shaped bodies, the greatest diameter of which corresponds to the short diameter 
of the containing tube. The bodies generally present the appearance of rings, 
having no apparent connection with the walls of the case which contains them. 
In many instances they are crowded together, and irregular in shape ; in others 
they are oval, and placed at equal distances. The fecula which I have seen in 
the globules seems to have no connection whatever with the bodies now men- 
tioned GEORGE DICKIE. 
Fig. 1 represents portions of different filaments very highly magnified. 
Jungermannia In the axillae of the leaves of Jungermannia pusilla, numerous 
small bodies frequently occur (anthers of some writers. ) They are of a white 
colour, and consist of a reticulated membrane ; each is supported on a short 
footstalk. On rupturing these bodies, numerous transparent particles issue 
forth ; the resemblance of these latter to fecula is very apparent, and on the ap- 
plication of iodine they become blue. It occurred to me that the bodies now 
mentioned might be perhaps one way, by which Jung, pusilla is propagated. I 
therefore placed some of them in circumstances which appeared to me to be 
favourable to germination, but after a lapse of several weeks, they had under- 
gone no alteration. Their true nature, therefore, still remains uncertain
