Hero, in this solitary and well chosen spot, we have three 

 distinctly separate yet closely contiguous sets of so-called 

 Druidical Circles. 



The first to the north consists of the usual outer circle of 

 isolated blocks ; within this, in the centre, is a circular cham- 

 ber, the wall of which extends outwards and is nearly equal 

 in thickness to the diameter of the chamber itself. 



The diameter of the chamber is 15 to 20 feet, is approach- 

 ed from the outer circle by a passage of about 2 feet wide 

 through the thickness of the surrounding wall. 



Several feet of this wall remain to prove that it was built 

 of stones in their natural condition, and so constructed as to 

 form, over the chamber, a spherical arch, constituting the 

 latter a hollow cone, so that when entire it must have ap- 

 peared very much like those untesthetic structures called 

 bottle-works, familiar to all who have visited Leith. 



The interior and exterior sides of the wall are faced with 

 large slabs of stone, inferior in size, however, to those con- 

 stituting the outer circle, the interspace being filled up with 

 loose stones, apparently thrown in at random. 



The same construction is observable in the passage of 

 communication. 



The spherical arched roof of the interior chamber is formed 

 by the gradual approximation to each other of the successive 

 courses of stone as they rise higher and higher. 



No. 2, which lies immediately south, is in a much more 

 dilapidated condition than that already described, but 

 amidst the paucity of its remaining mateiials there can easily 

 be traced the same form and construction. 



No. 3 is again in very much the same condition as No. 1, 

 and the description of which will equally apply to it. 



In short, however dilapidated they may be now, enough 

 remains to shew that as to material, form, structure, and 

 arrangement they have been fac-similes of each other. 



Allow me now to generalize these facts. 



1st, In the whole of these six Druidical structures there 

 are distinctly traceable three concentric circles in each.
