NATURAL HISTORY of NORWAY. 173 



The Ferro-if lands afford plenty of Chalcedonies, but which are Chalcedony, 

 not above twice the bignefs of a pea, very feldom reaching that of 

 a hazel-nut, of which fize 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 : " Chalcedonium iflandicum cri- 

 ftalloidem voco lapidem. Mafia eft unciarum duarum longitudine, 

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

 conftat albo, duro, cui nigredinis quidpiam permiftum 5 ex quo 

 efflorefcit crufta qusedam calcedonica, craffitie calami fcriptorii; 

 Haec vero ex fe papillaceas quafdam ftrias protrudit ejufdem fub- 

 ftantias, externa fuperficie afperas inftar facchari candidi, granulis 

 minutis micantes. Parte anteriore tres mnt papillae, quarum media 

 reliquis longior, una reliquis minor, verfus latiorem partem una 

 duplicata. Omnes hag papillae, ut et corporis ipfius tota fuperficies 

 fuperior quafi conglaciata eft, fplendentibus granulis cryftallinis af- 

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

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

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

 earth many white mufcle-mells, quite full ; an indifputable effecT: 

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

 felves into thefe fhells, where they afterwards became indurated - 3

Agate of feveral kinds are produced here, and I have fome Agate., 

 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 laid to be full of large veins of agate ; but Generally 

 fo 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 parfonao-e 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 Ferro- 

 iflands, Ol. Wormius mentions the following : « Quedam Turco- InMuf
