distinguished from Sertulariae by polypes growing on one side of
the branch, and not on both. Here is falcata, with its roots
twisted round a sea-weed. Here is cristata, on the same weed; and
here is a piece of the beautiful myriophyllum, which has been
battered in its long journey out of the deep water about the ore
rock. For all these you must consult Johnson's "Zoophytes," and
for a dozen smaller species, which you would probably find tangled
among them, or parasitic on the sea-weed. Here are Flustrae, or
sea-mats. This, which smells very like Verbena, is Flustra
coriacea (Pl. I. Fig. 2). That scurf on the frond of ore-weed is
F. lineata (Pl. Fig. 1). The glass bells twined about this
Sertularia are Campanularia syringa (Pl. I. Fig. 9); and here is a
tiny plant of Cellularia ciliata (Pl. I. Fig. 8). Look at it
through the field-glass; for it is truly wonderful. Each polype
cell is edged with whip-like spines, and on the back of some of
them is - what is it, but a live vulture's head, snapping and
snapping - what for?

Nay, reader, I am here to show you what can be seen: but as for
telling you what can be known, much more what cannot, I decline;
and refer you to Johnson's "Zoophytes," wherein you will find that
several species of polypes carry these same birds' heads: but
whether they be parts of the polype, and of what use they are, no
man living knoweth.

Next, what are the striped pears? They are sea-anemones, and of a
species only lately well known, Sagartia viduata, the snake-locked
anemone (Pl. V. Fig. 3(5)). They have been washed off the loose
stones to which they usually adhere by the pitiless roll of the
ground-swell; however, they are not so far gone, but that if you
