I. Account of Guemsey^ and the other Channel Islands^ by 

 J. Mac Culloch, M.D. F.L.S. Member of the Geological Society. 



1 HE 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 nume- 

 rous 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.
