  an hour。  Look at the Crinoids; or stalked star…fishes; the 〃Lilies
  of living stone;〃 which swarmed in the ancient seas; in vast
  variety; and in such numbers that whole beds of limestone are
  composed of their disjointed fragments; but which have vanished out
  of our modern seas; we know not why; till; a few years since;
  almost the only known living species was the exquisite and rare
  Pentacrinus asteria; from deep water off the Windward Isles of the
  West Indies。
  Of this you will see a specimen or two both at Liverpool and in the
  British Museum; and near them; probably; specimens of the new…old
  Crinoids; discovered of late years by Professor Sars; Mr。 Gwyn
  Jeffreys; Dr。 Carpenter; Dr。 Wyville Thomson; and the other deep…
  sea disciples of the mythic Glaucus; the fisherman; who; enamoured
  of the wonders of the sea; plunged into the blue abyss once and for
  all; and became himself 〃the blue old man of the sea。〃
  Next look at the corals; and Gorgonias; and all the sea…fern tribe
  of branching polypidoms; and last; but not least; at the glass
  sponges; first at the Euplectella; or Venus's flower…basket; which
  lives embedded in the mud of the seas of the Philippines; supported
  by a glass frill 〃standing up round it like an Elizabethan ruff。〃
  Twenty years ago there was but one specimen in Europe:  now you may
  buy one for a pound in any curiosity shop。  I advise you to do so;
  and to keep … as I have seen done … under a glass case; as a
  delight to your eyes; one of the most exquisite; both for form and
  texture; of natural objects。
  Then look at the Hyalonemas; or glass…rope ocean floor by a twisted
  wisp of strong flexible flint needles; somewhat on the principle of
  a screw…pile。  So strange and complicated is their structure; that
  naturalists for a long while could literally make neither head nor
  tail of them; as long as they had only Japanese specimens to study;
  some of which the Japanese dealers had; of malice prepense; stuck
  upside down into Pholas…borings in stones。  Which was top and which
  bottom; which the thing itself; and which special parasites growing
  on it; whether it was a sponge; or a zoophyte; or something else;
  at one time even whether it was natural; or artificial and a make…
  up; … could not be settled; even till a year or two since。  But the
  discovery of the same; or a similar; species in abundance from the
  Butt of the Lows down to Setubal on the Portuguese coast; where the
  deep…water shark fishers call it 〃sea…whip;〃 has given our savants
  specimens enough to make up their minds … that they really know
  little or nothing about it; and probably will never know。
  And do not forget; lastly; to ask; whether at Liverpool or at the
  British Museum; for the Holtenias and their congeners; … hollow
  sponges built up of glassy spicules; and rooted in the mud by glass
  hairs; in some cases between two and three feet long; as flexible
  and graceful as tresses of snow…white silk。
  Look at these; and a hundred kindred forms; and then see how nature
  is not only 〃maxima in minimis〃 … greatest in her least; but often
  〃pulcherrima in abditis〃 … fairest in her most hidden works; and
  how the Creative Spirit has lavished; as it were; unspeakable
  artistic skill on lowly…organized creature; never till now beheld
  by man; and buried; not only in foul mud; but in their own
  unsightly heap of living jelly。
  But so it was from the beginning; … and this planet was not made
  for man alone。  Countless ages before we appeared on earth the
  depths of the old chalk…ocean teemed with forms as beautiful and
  perfect as those; their lineal descendants; which the dredge now
  brings up from the Atlantic sea…floor; and if there were … as my
  reason tells me that there must have been … final moral causes for
  their existence; the only ones which we have a right to imagine are
  these … that all; down to the lowest Rhizopod; might delight
  themselves; however dimly; in existing; and that the Lord might
  delight Himself in them。
  Thus; much … alas! how little … about the wonders of the deep。  We;
  who are no deep…sea dredgers; must return humbly to the wonders of
  the shore。  And first; as after descending the gap in the sea…wall
  we walk along the ribbed floor of hard yellow sand; let me ask you
  to give a sharp look…out for a round grey disc; about as big as a
  penny…piece; peeping out on the surface。  No; that is not it; that
  little lump:  open it; and you will find within one of the common
  little Venus gallina。 … The closet collectors have given it some
  new name now; and no thanks to them:  they are always changing the
  names; instead of studying the live animals where Nature has put
  them; in which case they would have no time for word…inventing。
  Nay; I verify suspect that the names grow; like other things; at
  least; they get longer and longer and more jaw…breaking every year。
  The little bivalve; however; finding itself left by the tide; has
  wisely shut up its siphons; and; by means of its foot and its
  edges; buried itself in a comfortable bath of cool wet sand; till
  the sea shall come back; and make it safe to crawl and lounge about
  on the surface; smoking the sea…water instead of tobacco。  Neither
  is that depression what we seek。  Touch it; and out poke a pair of
  astonished and inquiring horns:  it is a long…armed crab; who saw
  us coming; and wisely shovelled himself into the sand by means of
  his nether…end。  Corystes Cassivelaunus is his name; which he is
  said to have acquired from the marks on his back; which are
  somewhat like a human face。  〃Those long antennae;〃 says my friend;
  Mr。 Lloyd (6) … I have not verified the fact; but believe it; as he
  knows a great deal about crabs; and I know next to nothing … 〃form
  a tube through which a current of water passes into the crab's
  gills; free from the surrounding sand。〃  Moreover; it is only the
  male who has those strangely long fore…arms and claws; the female
  contenting herself with limbs of a more moderate length。  Neither
  is that; though it might be; the hole down which what we seek has
  vanished:  but that burrow contains one of the long white razors
  which you saw cast on shore at Paignton。  The boys close by are
  boring for them with iron rods armed with a screw; and taking them
  in to sell in Torquay market; as excellent food。  But there is one;
  at last … a grey disc pouting up through the sand。  Touch it; and
  it is gone down; quick as light。  We must dig it out; and
  carefully; for it is a delicate monster。  At last; after ten
  minutes' careful work; we have brought up; from a foot depth or
  more … what?  A thick; dirty; slimy worm; without head or tail;
  form or colour。  A slug has more artistic beauty about him。  Be it
  so。  At home in the aquarium (where; alas! he will live but for a
  day or two; under the new irritation of light) he will make a very
  different figure。  That is one of the rarest of British sea…
  animals; Peachia hastata (Pl。 XII。 Fig。 1); which differs from most
  other British Actiniae in this; that instead of having like them a
  walking disc; it has a free open lower end; with which (I know not
  how) it buries itself upright in the sand; with its mouth just
  above the surface。  The figure on the left of the plate represents
  a curious cluster of papillae which project from one side of the
  mouth; and are the opening of the oviduct。  But his value consists;
  not merely in his beauty (though that; really; is not small); but
  in his belonging to what the long word…makers call an
  〃interosculant〃 group; … a party of genera and species which
  connect families scientifically far apart; filling up a fresh link
  in the great chain; or rather the great network; of zoological
  classification。  For here we have a simple; and; as it were; crude
  form; of which; if we dared to indulge in reveries; we might say
  that the Creative Mind realized it before either Actiniae or
  Holothurians; and then went on to perfect the idea contained in it
  in two different directions; dividing it into two different
  families; and making on its model; by adding new organs; and taking
  away old ones; in one direction the whole family of Actiniae (sea…
  anemones); and in a quite opposite one the Holothuriae; those
  strange sea…cucumbers; with their mouth…fringe of feathery gills;
  of which you shall see some anon。  Thus there has been; in the
  Creative Mind; as it gave life to new species; a development of the
  idea on which older species were created; in order … we may fancy …
  that every mesh of the great net might gradually be supplied; and
  there should be no gaps in the perfect variety of Nature's forms。
  This development is one which we must believe to be at least
  possible; if we allow that a Mind presides over the universe; and
  not a mere brute necessity; a Law (absurd misnomer) without a
  Lawgiver; and to it (strangely enough coincidi
