regular fhape, and of a considerable I judged 
from the account, which I had of them, that they 
relembied thofe, which formed, what is called in Ire- 
land, the Giants-caufey. I was more and more con- 
firmed in this notion, when I faw fome of thofe 
fiones in a pavement. Upon finding, that the quarry, 
whence they were taken, was at no great difiance, I 
went to it the day following. It is in a wood, upon 
the declivity of a hill. It has not yet been dug into 
above twenty feet deep, and forty long. I diftindtly 
perceived, that this quarry confified of a mafs of 
fiones of an almofi regular form. I examined care- 
fully all thole, which prefentcd themfelves to my 
view. I caufed fome of them to be detached from 
the reft ; and I fearched with attention the parts 
about this quarry. I could not difcover at what 
depth thefe fiones are to be found under-ground. 
They appear very near the Surface of the earth, where 
the quarry, which I am fpeaking of, lies. And 
there was a pretty confiderable fpace of grounds in 
which the top of the fiones appeared, and where 
it was eafy to examine the Shape of their upper ends. 
It is very far from being the fame in all of them : 
but when a great number of them are compared 
with one another, we find reafon to conclude, that 
the hexagonal form is the moft common. The more 
regular the figure of thefe extremities is, the more it 
approaches to that of an hexagon. The two ends 
of every ftone appeared to me, for the moft part, to 
have the fame fhape. The fides of the ftone are of 
the fame form with the ends, and are plain. Every 
ftone is therefore a prifm of a certain number of 
Sides. They are from three to eight fides, and of
