  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
  take　one　of　them　home；　and　put　it　in　a　jar　of　water；　it　will　expand
  into　a　delicate　compound　flower；　which　can　neither　be　described　nor
  painted；　of　long　pellucid　tentacles；　hanging　like　a　thin　bluish
  cloud　over　a　disk　of　mottled　brown　and　grey。
  Here；　adhering　to　this　large　whelk；　is　another；　but　far　larger　and
  coarser。　　It　is　Sagartia　parasitica；　one　of　our　largest　British
  species；　and　most　singular　in　this；　that　it　is　almost　always　（in
  Torbay；　at　least；）　found　adhering　to　a　whelk：　　but　never　to　a　live
  one；　and　for　this　reason。　　The　live　whelk　（as　you　may　see　for
  yourself　when　the　tide　is　out）　burrows　in　the　sand　in　chase　of
  hapless　bivalve　shells；　whom　he　bores　through　with　his　sharp　tongue
  （always；　cunning　fellow；　close　to　the　hinge；　where　the　fish　is）；
  and　then　sucks　out　their　life。　　Now；　if　the　anemone　stuck　to　him；
  it　would　be　carried　under　the　sand　daily；　to　its　own　disgust。　　It
  prefers；　therefore；　the　dead　whelk；　inhabited　by　a　soldier　crab；
  Pagurus　Bernhardi　（Pl。　II。　　Fig。　2）；　of　which　you　may　find　a　dozen
  anywhere　as　the　tide　goes　out；　and　travels　about　at　the　crab's
  expense；　sharing　with　him　the　offal　which　is　his　food。　　Note；
  moreover；　that　the　soldier　crab　is　the　most　hasty　and　blundering　of
  marine　animals；　as　active　as　a　monkey；　and　as　subject　to　panics　as
  a　horse；　wherefore　the　poor　anemone　on　his　back　must　have　a　hard
  life　of　it；　being　knocked　about　against　rocks　and　shells；　without
  warning；　from　morn　to　night　and　night　to　morn。　　Against　which
  danger；　kind　Nature；　ever　MAXIMA　IN　MINIMIS；　has　provided　by
  fitting　him　with　a　stout　leather　coat；　which　she　has　given；　I
  believe；　to　no　other　of　his　family。
  Next；　for　the　babies'　heads；　covered　with　prickles；　instead　of
  hair。　　They　are　sea…urchins；　Amphidotus　cordatus；　which　burrow　by
  thousands　in　the　sand。　　These　are　of　that　Spatangoid　form；　which
  you　will　often　find　fossil　in　the　chalk；　and　which　shepherd　boys
  call　snakes'　heads。　　We　shall　soon　find　another　sort；　an　Echinus；
  and　have　time　to　talk　over　these　most　strange　（in　my　eyes）　of　all
  living　animals。
  There　are　a　hundred　more　things　to　be　talked　of　here：　　but　we　must
  defer　the　examination　of　them　till　our　return；　for　it　wants　an　hour
  yet　of　the　dead　low　spring…tide；　and　ere　we　go　home；　we　will　spend
  a　few　minutes　at　least　on　the　rocks　at　Livermead；　where　awaits　us　a
  strong…backed　quarryman；　with　a　strong…backed　crowbar；　as　is　to　be
  hoped　（for　he　snapped　one　right　across　there　yesterday；　falling
  miserably　on　his　back　into　a　pool　thereby）；　and　we　will　verify　Mr。
  Gosse's　observation；　that　…
  〃When　once　we　have　begun　to　look　with　curiosity　on　the　strange
  things　that　ordinary　people　pass　over　without　notice；　our　wonder　is
  continually　excited　by　the　variety　of　phase；　and　often　by　the
  uncouthness　of　form；　under　which　some　of　the　meaner　creatures　are
  presented　to　us。　　And　this　is　very　specially　the　case　with　the
  inhabitants　of　the　sea。　　We　can　scarcely　poke　or　pry　for　an　hour
  among　the　rocks；　at　low…water　mark；　or　walk；　with　an　observant
  downcast　eye；　along　the　beach　after　a　gale；　without　finding　some
  oddly…fashioned；　suspicious…looking　being；　unlike　any　form　of　life
  that　we　have　seen　before。　　The　dark　concealed　interior　of　the　sea
  becomes　thus　invested　with　a　fresh　mystery；　its　vast　recesses
  appear　to　be　stored　with　all　imaginable　forms；　and　we　are　tempted
  to　think　there　must　be　multitudes　of　living　creatures　whose　very
  figure　and　structure　have　never　yet　been　suspected。

  Neither　now　need　we　indulge　in　another　theory　which　had　a　certain

  The　facts　are；　first　that　water；　being　all　but　incompressible；　is
  hardly　any　heavier；　and　just　as　liquid；　at　the　greatest　depth；　than
  at　the　surface；　and　that　therefore　animals　can　move　as　freely　in　it
  in　deep　as　in　shallow　water；　and　next；　that　as　the　fluids　inside
  the　body　of　a　sea　animal　must　be　at　the　same　pressure　as　that　of
  the　water　outside　it；　the　two　pressures　must　balance　each　other；
  and　the　body；　instead　of　being　crushed　in；　may　be　unconscious　that
  it　is　living　under　a　weight　of　two　or　three　miles　of　water。　　But　so
  it　is；　as　we　gather　our　curiosities　at　low…tide　mark；　or　haul　the
  dredge　a　mile　or　two　out　at　sea；　we　may　allow　our　fancy　to　range
  freely　out　to　the　westward；　and　down　over　the　subaqueous　cliffs　of
  the　hundred…fathom　line；　which　mark　the　old　shore　of　the　British
  Isles；　or　rather　of　a　time　when　Britain　and　Ireland　were　part　of
  the　continent；　through　water　a　mile；　and　two；　and　three　miles　deep；
  into　total　darkness；　and　icy　cold；　and　a　pressure　which；　in　the
