I. Account of Guernsey, and the other Channel Islands, by J. MacCulloch, M.D. F.L.S. Member of the Geological Society.
The few following notes may help to explain the maps on which I have sketched the leading features of the mineralogy of the Channel Islands. The specimens which I collected having been mislaid, I am unable to give a more particular description of the stones which I have noticed.
These islands are situated in St. Michael's Bay, and from the general direction of the land, the form of the bottom, and the numerous rocks which are scattered around, may possibly have once been more intimately connected with the Coast of Normandy. Of this however, any further evidence, arising from continuity or similarity of strata, is, for the present at least, inaccessible.
