COMPARISONS OF THE L'ISLET DISCOVERY WITH 

 GUERNSEY DOLMENS. 



Certain divergences in details are noticeable between this 

 and the dolmens hitherto found in Guernsey and the Channel 

 Islands.

 longer axis North and South 

 and are laid transversely to the 

 length of the structure.

 more to each capstone and are 

 always in the form of a menhir, 

 set on their ends.

 covering stone are on their 

 sides and are only two in 

 number.

 buried in the ground and rest 

 on the underlying rock.
