NATURAL HISTORY of NORWAY. 173 



The Ferro-iilands afford plenty of Chalcedonies, but which are chalcedony, 

 hot above twice the bignefs of a pea, very feldom reaching that of 

 a hazel-nut, of which lize I have fome in my collection. The Mu- 

 feum Womianum, page 98, mentions two of an oblong figure, and 

 of the bignefs of a man's thumb, and he alfo fpeaks in the follow- 

 ing manner of thofe of Iceland : n Chalcedonium iflandicum cri- 

 ftalloidem voco lapidem. Mafia eft unciarum duarum longitudine, 

 totidem latitudine, qua latior eft. Parte qua cauli adhaefit, faxo 

 conftat albo, duro, cui nigredinis quidpiam permiftum^ ex quo 

 eftlorefcit crufta quaedam ealcedonica, craffitie calami fcriptorii. 

 Hage vero ex fe papillaeeas quafdam ftrias protrudit ejufdem fab- 

 flantise,- externa fuperficie afperas inftar facchari candid i, granulis 

 minutis micantes. Parte anteriore tres funt papillae, quarum media 

 reliquis longior, una reliquis minor, verfus latiorem partem una 

 duplicata. Omnes has papillae, ut et corporis iplius tota fuperflcies 

 fuperior quail conglaciata eft, fplendentibus granulis cryftallinis af- 

 pera. Elegans certe eft, a nemine, quod fciam, defcripta." Of 

 thefe glittering and angular little grains, which are laid to adhere 

 to the ifland Chalcedonies, there are frequently found deep in the 

 earth many white mufcle-fhells, quite full ; an indisputable effedfc 

 of the deluge ; thefe bodies, when liquid, having infinuated them- 

 felves into thefe fhells, where they afterwards became indurated 5 

 and I myfelf have fome of this kind in my mufasum*

Agate of feveral kinds are produced here, and I have fomeAgac^, 

 pieces of red and yellowifh, which were found in Sundmoer, and 

 the fame abound in other places. The ground near the parfonage 

 of Findaas, is faid to be full of large veins of agate ; but generally 

 Co hard as not to be wrought in any other manner than by grind- 

 ing. Baron Holberg, in his Prefent State of Denmark and Nor- 

 way, fays the like of a kind of hard but beautiful jafper, found in 

 . a mountain two Norway miles N. W. of the parfonage of Sille- 

 jord, of which governor Wibel, in the year 1726, had a fet of 

 tea-cups made, for a prefent to his majefty Frederic IV. 



Among feveral fmall pieces of green jafper, found in the Ferfo- 

 iflands, Ol. Wormius mentions the following : " Quedam Turco- In ^ >
