nature and formation of the conglomerate; it is not even possible 

 to see from the material how the rock is stratified. A conglomerate 

 with baryte as the matrix is, however, probably of rare occurrence. 



Neither the labels in the collection nor Dr. Wegeneh's diary- 

 notes make any definite statement respecting the thickness of the 

 conglomerate, but from the diary it is clearly evident that, upwards, 

 it passes into sandstone, and, in the lower part, it alternates with 

 limestone. For, from 130 metres above sea-level there has been 

 obtained material {N:o 176), of light limestone, regarding which the 

 diary states as follows: — "130 m. Heller Kalk mit wenigen Fossilien, 

 in 3 m. dicken Bändern wechsellagernd mil dem Conglomerate, das 

 nach oben immer feinkörniger wird and bei 150 m. schon fast einem 

 Sandstein gleich sieht {N:o 183). Zerfällt leicht in rote Erde". 



The limestone is a very light yellow-gray, finely crystalline and 

 very compact, with a few glide surfaces. No fossils were observable 

 with the pocket lens. The sandstone from 150 metres is very loose, 

 and consists of unevenly large quartz-grains, which, in the unim- 

 portant material at hand, are sometimes as large as a pea, and are 

 cemented together by means of a red-brown matrix which seems 

 to contain clay and mica. 



At 175 metres there was found a thick bed of limestone, of 

 which 10 metres lay exposed ; it was rich in fossils and a drawing 

 in the diary indicates rugose corals. The fragments that have been 

 brought home {N:os 182 and 18A) show, however, little of determinable 

 fossil remains. N:o 184^ is a gray, dense, somewhat clayey limestone 

 and, of larger fossil fragments, contains the umbonal part of a brachio- 

 pod (probably a Spirifer) and other fragments of fossils; among 

 others brachiopod spines. Specimen N:o 182 seems to consist of 

 another species of limestone, as far as can be made from the unim- 

 portant material at hand. On the one surface, which is weathered 

 and worn, or polished by the wind (by means of snow or sand) 

 the rock is of a light-gray colour, and here can be seen a number 

 of small fragments of fossils, mostly stems of crinoids, and also a 

 number of small Fusulinœ. On the inner surface the material shows 

 a somewhat clayey and darker matrix, which points to the presence 

 of bituminous substances. It reminds one somewhat of other bitu- 

 minous limestones of this series. 



At 190 metres above the sea there begins a gray-green, some- 

 what calcareous sandstone (N:o 186), fairly fine-grained, containing 

 a pretty large number of grains of felspar, together W4th mica, both 

 dark and white; this sandstone, consequently, is formed of products 

 of degradation, which have been but little altered, probably from a
