172 Mr. RAY’j Itineraries, 
at Ibme Diftance from the Root, and 
narrow, refembling Thongs of Whit- 
Leather. A little above the reft we 
found, in all that we obferved, a 
round Circle like a Rotula about the 
Stalk, of about an Inch Diameter or 
more, of the fame Subftance with 
the Fucus^ but thinner. This Plant 
might be better exprefled by a Figure, 
than delcribed by Words. All along 
in the Cliffs, and on the Shore, are 
/ found in great Plenty the Serpent- 
Stones^ called by Naturalifts in Latin.^ 
Cornua Ammonis. We were fome- 
what puzzled to get them entire out 
of their Matrices^ the ufual Way of 
heating them in the Fire very hot, 
and then quenching them in the 
Water, not always fucceeding; many 
of thefe Stones were imperfedl. In 
this CHff or Rock (which is nothing 
but Alum-Mine) we found alfo Plenty 
of the Lapides belemttites, or Thunder- 
Stones,
