From observing this method in nature, we shall the easier account for the progress of those generations of young testaceous polypes of this coral; which appear to us succeeding each other, and raising themselves up from the root or base, passing along the stem and branches, and covering the whole anew with their shelly cases: and in this their passage upwards we may observe, in the specimen before us, how they have involved and incrusted the small lateral branches of the former generation, so as almost to hide their appearance. From hence we may trace them extending themselves to the extremities of the upper branches, and there forming a new series of slender twigs, proportionable to those which they had just covered, still keeping order and exact symmetry in the whole structure. The distinguishing character of this red coral, after we have considered its fistulous texture, is the knotty joints, of which it is composed: these appear more distinct, and are placed at a greater distance, in the smaller branches than the large; and, as we descend to the trunk, the traces of these inequalities but just appear. From these protuberances, or knots, the lateral branches take their rise; and as these and the leading branches grow up together, they frequently inosculate at these joints, forming a kind of network, like what we observe in many of those species of keratophyta, which are called sea-fans. The surface of this coral, when recent, is covered with a mealy friable matter, of a yellow colour, not unlike that of the true red coral, but much fuller of little raised starry cells. The figure of these cells is owing to the radiated position of the claws of the polypes. Upon removing this friable matter, we observe, that the polypes of these cells have had a communication with a small hole or opening into one of the tubes, that lie immediately under it. This frequent intervention of the openings of the small tubes, or their ramifications, between the sides of the larger ones, makes the latter appear more irregular, and not so parallel, as in the true red coral; where we find fewer stars; and, where those occur, we may observe it always alters the direction of the tubes. I must further remark to you, that many of the tubes of this coral appear, thro’ a magnifying glass, full of small holes, like those I have described in the keratophyton (_Plate_ 26. _Fig._ G. _p._ 62. _of my Essay on Corallines_); and these holes will appear more distinctly to you, when you examine the half tubes, or broken irregular ones, on the stem and great branches of this coral. Further, if you compare the transverse section, at the base of this coral, with a section of a common Rattan cane, they will both appear full of holes in the same regular order, and of nearly the same diameter: whereas the tubes, on the surface of the stem of this coral, look as irregular as so many holes pierced or eaten out by worms.
