82 OFSTONES. 



All thefe bodies are frequent both in {tone and loofe on the 

 (bores of our alpine rivulets, and in marble or limcftone quar- 

 ries. They are alfo plentiful on many parts of the fea-fhore, 

 particularly among the rocks at Holy I/land, where they are called 

 by the general name of St. Cuthbtrfs Beads, and are fo called by 

 Mr. Ray (s). We find them frequently immerfcd in nodules of 

 iron-ore, with fair fpecimens of bivalve fliells, on the ihore of 

 the brook, and in the clay-bank at Simonburn ; alfo fingle ones fo 

 filled with the ore, that they feem only thin jointed cafes, crufts, 

 or coverings to it. We fometimes find them in maffes of red iron- 

 ftone on the more of the brook at Gofton, of a blood-red through- 

 out, in vaft numbers. On the fea-more at Druridge, near Wid- 

 drington, I have found them in a red flone, of a beautiful white,, 

 with wavy red lines running through their plated iubftunce,. 

 both entrochoi and after'ue, the ftellar cavities of the latter, red. I 

 have alfo found the cavity of the belemnite red, with a white ci;vJe, 

 on a grey ground, in a red ftone on the more of the brook be- 

 low Simonburn-ca.ft.le. They are found both in flone and clay in 

 fuch innumerable quantities, and with fuch numerous difloca- 

 tions and bruifes, in company with other marine bodies, that 

 it is both entertaining and aftoniming to fee them. Lithologifts 

 of great name differ in their opinions concerning their origin. 

 The famous Dr. Lifter (t), and Mr. Beaumont of Stoney. Eqfton, in 

 Somerfetfljire (u}, refer them to the mineral kingdom. The 

 learned keeper of the Aflmolean Mufeum, Edivard Lbivyd (v), 

 and the three curious foreigners, Auguftin Scilla (wj, Gualtieri (x},
