In fig. 2. he gives us an elegant painting of a geniculated red conserva for a coralline, surrounded, as is very common, by many species of small corallines and escharas. And in fig. 4. he gives us a drawing of one of the tubular corallines, with the head of the animal at the top of it; the stem of this is incrusted with four different corallines and escharas, like the conserva fig 2.; and then he asks, which of these five polypes made the tubular coralline? To give him some proof of the animal nature of this coralline, let him consult Ray’s Synopsis, ed. 3. p. 34. n. 4. and there he will find one of his species, called _adianti aurei minimi facie planta marina_, taken notice of so long ago as the year 1713. by Dr. Lloyd, as a zoophyte, from its stem or tube’s being full of a thick reddish liquor, rather resembling blood than the juice of a plant; which, upon pressing the stem, communicated with the little head at top. His fourth argument is, That as upon one and the same coralline plant you shall find different kind of polypes; so, in different species of coralline, the same polypes; and, to confirm this, he quotes my Essay on Corallines; where I have remarked, that the polypes in the denticles of the setaceous or bristly coralline, Nº. 16. appear to be like those, that are on the lobster’s horn coralline, Nº. 19. And to illustrate this, he observes, that bees and wasps always build their cells invariably the same; and that therefore these two corallines should be the same.
