46 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [NORW. POL. EXP. 



found lying loose on the talus at a height of 100 feet (30 m.) behind Elm- 

 wood; cf. p. 16, No. 4. 



Judging from their state of preservation, none of these pieces have been 

 found in situ. 



No. 2. A similar grey-brown, hard, phosphoritic day found loose at 

 a height of ca. 370450 feet (113127 m.) on July 14th 1896, south-western 

 end of Windy Gully; cf. p. 13, "Medium horizon". This piece furnished the 

 calcareous ammonite figured on pi. II. fig. 12. 



No. 3. Phosphoritic (and calcareous) day nodules are numerous in the 

 material before me. They vary from the size of a nut to that of a clenched 

 fist. They are composed of a dark brown or black nucleus of phosphorite, 

 and a lighter gray or brown soft crust of clay which, evidently owing to 

 weathering only, is free from phosphorite. 



a). Phosphoritic nodules with light-gray argillaceous weathered crust. 

 Organic remains can only be proved in a few (2) pieces. (Ammonite- and 

 Serpula-remains). A quantity of pieces were found loose on July 12th 1896, 

 100200 feet (3060 m.) above the sea, l 1 ^ klm. NW. from Elmwood, 

 "doubtful horizon", cf. p. 17. Others were found loose on July 14th 1896, 

 at a height of ca. 370450 feet (113137 m.) at the south-western end of 

 Windy Gully, "Medium horizon", cf. p. 13. 



b). Phosphoritic nodules with darker argillaceous weathered crust, from 

 July 14th 1896, found loose at a height of 400 feet, south-western end of 

 Windy Gully. The nodules contain pieces of the phragmocones of a large 

 species of belemnites. I have nothing to add to the description of the 



* 



microscopic examination of the phosphoritic nodules, given by Messrs. Newton 

 and Teall 1 . 



Mr. A. Schwager, chemist at the "koniglich bayrisches Ober-Berg-Amt", 

 Munich, had the kindness to examine specimens of phosphoritic nodules. The 

 examination proved that besides phosphate of lime, 8% Ca Cos and 7'32% 

 Si 02 the nodules contain a ferruginous, argillaceous substance to an amount 

 corresponding to Si 02, and little organic substance 2 .

his kind assistance.
