[Footnote 81: Dr. Buckland's "Reliquia Diluviana" contains a full account of the most remarkable ossiferous caverns and their contents.] Similar ossiferous caves occur in England; of these, the most remarkable now accessible are Kent's Hole, near Torquay, and Banwell Cave, in the Mendip Hills, near the village of Banwell. The latter may be easily visited, as the Exeter railway passes within three miles of the village, and there is a station, with vehicles to convey passengers to Banwell. II. The Belemnite. (Plates LIX. and LX.) Among the innumerable relics which abound in the secondary deposits, there are perhaps no fossil bodies that have excited so much curiosity, or given rise to so many fanciful conjectures as to their nature and origin, as the long, cylindrical, fusiform, crystalline stones, called _Belemnites_ by naturalists, and _thunderbolts_ by common observers. Mr. Parkinson gives an amusing account (vol. iii. p. 122) of the discordant opinions entertained at various times respecting the nature of these bodies. It would be irrelevant to dwell on the history of the successive attempts that have been made to elucidate the origin and structure of the Belemnite. It will suffice to describe concisely the present state of our knowledge as to the organization of the original. Mr. Miller, in 1823,[82] showed that the Belemnite was the rostrum or osselet of an animal allied to the Sepia, or Cuttle-fish, and gave a restored outline of the supposed form of the original, with the Belemnite in its presumed natural situation. Dr. Buckland and M. Agassiz imagined that they had traced a natural connexion between certain species of Belemnites that abound in the Lias, and the ink bag and other soft parts of the Sepiæ or Calamaries found associated with them; and they suggested the name of _Belemno-sepia_ for the supposed animal of the Belemnite,[83] [Footnote 82: Geological Transactions, New Series, vol. ii.; and Dr. Buckland's Bridgewater Essay.] [Footnote 83: Bridgewater Essay, p. 374.]
