Are they of the class of the ulvae, confervae, or fuci? to be welcomed as old acquaintance, or, hitherto unnoticed, to be added to the catalogue of Nature's endless stores? And what are those corals, that, like mimic tenants of the forest, extend their graceful boughs! Look at the variety of shells which are adhering to its sides.
Again, the male element may reach the female element, but be incapable of causing an embryo to be developed, as seems to have been the case with some of Thuret's experiments on Fuci. No explanation can be given of these facts, any more than why certain trees cannot be grafted on others. Lastly, an embryo may be developed, and then perish at an early period.
That portion of the Atlantic between the 22d and 34th parallels of latitude, and 26th and 58th meridians of longitude, is generally covered with fuci, and is termed by the Portuguese, mar do sargasso, or grassy sea.
Sunt enim pompae istae omnes, et ceremoniae Papistisae, nihil aliud quam fuci meretricii, ad hoc excogitati, ut homines ad spiritualem scortationem alliciantur.
It has also been observed that when pollen of one species is placed on the stigma of a distantly allied species, though the pollen-tubes protrude, they do not penetrate the stigmatic surface. Again, the male element may reach the female element, but be incapable of causing an embryo to be developed, as seems to have been the case with some of Thuret's experiments on Fuci.
Darwin, of plants which are more fertile with the pollen of another species than with their own; and there are others, such as certain 'fuci', whose male element will fertilize the ovule of a plant of distinct species, while the males of the latter species are ineffective with the females of the first.
And he establishes that the fuci of these early rocks speak of a torrid climate, although they may be found in what are now temperate regions; he also states that those of the higher rocks betoken, as we ascend, a gradually diminishing temperature.
In the meantime, the Fuci and Algæ, with the Corallines and Madrepores, would transform themselves into fish, and gradually populate all the submarine portions of the globe. Although the writers of this delicious drollery seem to have had Dr.
