By the great map of Iceland, made by the dire£Gon of the king oi Denmark, 

 and completed in 1734, by Cmpf, military furveyor, it appears that fome of the 

 jokkuls, or mountains, cafed with ice, have been fwallowed up by the convulfions 

 of the earth, in very diftant periods. Thofe of Breida-merkar and Skeida, in 

 Skaftafield Syjfel, are given as inftances. 



Probably the great vatns, or lakes, with which Iceland abounds, may have been

 am indebted for the preceding tranflatious, records feveral inftances in other parts
