hexagon (tones, each about a foot deep, and about 
nine inches over. They form a fmooth uniform 
pavement 5 and the (ides of all the (tones lie extremely 
contiguous, or clofe. Immediately below this upper 
pavement, lies another exactly like it. The pillars 
are jointed exactly like thofe of the Giants-caufeway, 
and are laid with their concavities downward, and 
their convexities upward ; and their hollows are 
as much in proportion to thefe pillars, which are 
(mailer, as they are in thofe of the Giants-caufeway. 
Thefe places are about 200 miles northward diftant 
from the Giants-caufeway. 
If your Lordfhip chules to communicate this ac-

pleafure. 
I am, 
With great refpedt. 
My Lord, 
Your Lordlhip’s 
Mod devoted and
