This work affords the following condensed view of the geologi- 

 cal series represented by the rocks and strata of Spitzbergen 

 (pp. 50, 51.) 



I. Crystalline E.ocks. 



1 . Granite and gneiss. 



2. Vertical and contorted strata of mica and hornblende- 

 schist^ with beds of quartzite, crystalline limestone, and 

 dolomite. 



II. Hecla-Hook Formation. 



1. Strata, at least 1,500 feet in thickness, with fossils, 

 consisting of red and green clay-slate, grey white- veined 

 limestone, and quartzite. 



2. Red ferruginous slates and conglomerates, without fos- 

 sils ; of less extent and unascertained thickness. 



III. Mountain-limestone. 



1. Ryss-Island limestone, or rather dolomite, non-fossili- 

 ferous ; traversed by beds of quartzite and flint. Thick- 

 ness about 500 feet. 



2. Cape-Fanshawe strata, containing Corals ; 1,000 feet at 

 the most in thickness. 



3. Layers of hyperite. 



4. Upper part of the Mountain-limestone, consisting of 

 calcareous sandstone, limestone, gypsum, and flint, 

 abounding in fossils, and 2,000 feet in thickness. Be- 

 tween the strata are extensive seams of hyperite. 



5. A very extensive and regular bed of hyperite, stretching 

 from Mount Edlund to the Thousand Islands. 



IV. Triassic Formation. 



Black bituminous shale, stratified hyperite, limestone, copro- 

 lite beds, and sandstone, with remains of Saurians,* 

 Nautilus, Ammonites, &c. ; about 1,500 feet in thick- 

 ness. 



V. Jurassic Formation. 



Shales, limestone, and sandstone, abounding in pyrites, and 

 traversed by a small seam of hyperite. At Mount 

 Agardh the thickness amounts to 1,200 feet. 



* Described and named as Ichthyosaurus polaris, Icht. Nordenskiceldii, and 

 Acrodus Spitsbergensis, by J. W. Hulke, Esq., F.B.S., &c., in the "Bihang
