Description of the GRAVELS from SPITZBEIIGEN. 

 By J. PRESTWICH, Esq. F.G.S. 



1. Gravel from Bell Sound,, 60 feet above high-water 

 mark. Grey gravel of small subangular fragments of 

 dark-grey argillaceous and quartzose slaty rocks, some 

 portions calcareous, and a few fragments of grey sand 

 stone, mixed with a small proportion of earth. None of 

 the fragments are above two ounces in weight, the bulk 

 being of small size (seventy to the ounce). Amongst 

 these subangular fragments there are, however, a few 

 small round pebbles of a dark- grey limestone, and a few 

 perfectly angular fragments of slate. 



There are no shells, nor any characters on any of the 

 fragments in the gravel to indicate a beach-origin. The 

 mass, in fact, looks much more like the smaller frag 

 ments of a moraine. None of the fragments, however, 

 are scratched or striated. 



2. Gravel from Bell Sound, 20 feet above high-water. 

 Dark-coloured grit, clean and uniform in texture, con 

 sisting of small subangular fragments of a black horn 

 blende slate (like that of No. 4) about the size of cress- 

 seed, with a very few flattish pebbles of the size of peas, 

 and still fewer rounded pebbles of the size of marbles. 

 There are no fragments of shells. 



3. Gravel from an island in Bell- Sound, a little above 

 high-water. Small greyish-green gravel of flat angular 

 fragments of greenish mica-slate, with a few pieces of 

 quartz. None of the fragments are an ounce in weight. 

 The bulk consists of pieces of about thirty to the ounce. 

 No matrix of any sort. No fragments of shells. This 

 gravel has the appearance of rock- debris in situ. 



4. Gravel from Bell Sound, half-way betAveen high-
