without any passage leading to them.* Those consist- 
ing of chambers and a long entrance passage, covered 
by slabs, within a large tumulus of earth, as at Wellow, 
near Stoney Littleton ; at Eodmarton ; at Uley ; and at

lechs, in the Channel Islands, I do not therefore allude 
to monuments such as we call Cromlechs; which last, 
though probably sepulchral, have not yet been found to

Limpet shells are also used for mortar.

Sea-birds feed on the Patella, and Mr. Gatcorabe, in
