N0 . 2.] GEOLOGICAL SKETCH BY NANSEN. 5 



Dr. J. F. POMPECKJ undertook the examination of this collection, 

 which, however, does not contain much that has not been found by 

 Koettlitz. But as Pompeckj does not agree with Mr. E. T. Newton, who has 

 described Kcettlitz's collection of fossils, on several rather important points as 

 regards the determination of the fossils, and the exact horizon of the various 

 strata, etc., I hope his paper will throw some additional light on the subject, 

 and may be read with much interest. 



Dr. Pompeckj has asked me to accompany his paper with a sketch of 

 the general features in the geological structure of Cape Flora, and the descrip- 

 tion of the localities where the fossils were found. In doing this, I feel it to 

 be my pleasant duty, first of all to express my sincere thanks to Mr. FREDE- 

 RICK JACKSON for the kind way in which he helped me in my geological 

 researches while I was his guest at Elmwood. I also use this welcome op- 

 portunity of thanking Dr. REGINALD K<ETTLITZ for his most valuable assistance 

 and companionship. He took me to the places where, before my arrival, he 

 had already found fossils, or had observed anything of importance; and had 

 it not been for him, I should certainly not have been able to do what little 

 I did, during the few days which were at my disposal. 



I agree with Koattlitz on all essential points, and have nothing new of 

 importance to add to what he has already said. In some respects this sketch 

 may, however, supplement his descriptions, and thus help to explain more 

 fully the conditions and circumstances under which the most northern Jurassic 

 fossils ever known have been found. 



Cape Flora, situated in circ. 79 56* N. Lat. and circ. 49 40' E. Long, 

 is the western extremity of the long and narrow peninsula which forms the 

 south-western part of Northbrook Island. 



A deep valley, Windy Gully, the bottom of which is only 16'8 metres 

 (55 feet) 1 above the sea, passes from north to south straight across this nar- 

 row peninsula, about three kilometres east of its western extremity, thus 

 separating the mass of Cape Flora from the eastern part of the island, and 

 making it an isolated hill of no great extent. 



1 Dr. Koettlitz says that Windy Gully B is about 1 mile long and 500 yards wide, with 

 a general surface about 100 feet above the sea. Some parts, however, rise to greater 

 elevations. The floor is covered over with rounded, water-worn, subangular and 

 angular stones and boulders, together with a dark, tenacious mud" (1. c. p. 623). 

 I suppose these 100 feet are not meant for the actual bottom of the valley, for this, 

 according to my measurements, was 55 feet at its highest level.
