It consists of a thin, straight, fleshy stem, with alternate rows of polypi on each side, and surrounding an elastic stony axis, varying in length from eight inches to two feet. The stem at one extremity is truncate, but at the other is terminated by a vermiform fleshy appendage.
This is so analogous to the manner in which the buds of trees appear to be produced, that these polypi may be considered as all male animals, producing embryons, which require no mother to supply them with a nidus, or with nutriment, and oxygenation.
There was plenty to amuse those who had a taste for natural history even when no land was in sight, and the doctor, who was a great naturalist, was constantly on the qui vive, for the sea teemed with squid, medusae, polypi, and flying-fish.
We may consider the polypi in a zoophyte, or the buds in a tree, as cases where the division of the individual has not been completely effected. Certainly in the case of trees, and judging from analogy in that of corallines, the individuals propagated by buds seem more intimately related to each other, than eggs or seeds are to their parents.
Nostrils, The. The disease called Polypus, affecting the mouth or nostril with growths which are usually removed by force, is one of those troubles curable by proper use of vinegar or weak acetic acid. The extraction of the Polypi is painful, and we have ourselves seen them so completely cured, that it is a pity not to make very widely known a method of avoiding extraction.
It was then ten in the morning; the rays of the sun struck the surface of the waves at rather an oblique angle, and at the touch of their light, decomposed by refraction as through a prism, flowers, rocks, plants, shells, and polypi were shaded at the edges by the seven solar colours.
Almost all the leaves, excepting those that float on the surface, are so thickly incrusted with corallines as to be of a white colour. We find exquisitely delicate structures, some inhabited by simple hydra-like polypi, others by more organized kinds, and beautiful compound Ascidiae. On the leaves, also, various patelliform shells, Trochi, uncovered molluscs, and some bivalves are attached.
In the serpula they have already become separate. How feeble this attempt is to individuate, is most clearly shown in their mode of generation. Notwithstanding the report of Professor Pallas, it still remains doubtful whether there exists any actual copulation among the polypi. The mere existence of a polypus suffices for its endless multiplication.
Beyond this stood her house, in the centre of a strange forest, in which all the trees and flowers were polypi, half animals and half plants; they looked like serpents with a hundred heads growing out of the ground. The branches were long slimy arms, with fingers like flexible worms, moving limb after limb from the root to the top.
Of these polypi, in a large specimen, there must be many thousands; yet we see that they act by one movement: they have also one central axis connected with a system of obscure circulation, and the ova are produced in an organ distinct from the separate individuals.
