In the first part of this paper, the author endeavoured to shew, from a comparison of various observations of the red prominences seen at the eclipse of the 28th July 1851, that those objects were not mere optical phenomena, but that they actually existed in the sun.
The object of the present communication is to offer some conjectures regarding the nature of the red prominences, and their possible connection with other solar phenomena.
