 shales with the shales at Shineton.

1. "On Sandworn Stones from New Zealand." By John D. 

 Enys, Esq., F.G.S. 



The author exhibited specimens of sandworn pebbles from near 

 Wellington in New Zealand, and described their mode of occurrence. 

 They are found on an isthmus rising but little above the sea, and 

 about a mile wide, and having on each side a line of low sand-hills, 

 separated by a flat space of clayey sand, on which the stones rest. 

 The isthmus separates two baj's, on each side of which the ground 

 is high, and hence the jDrevailing winds (which are north-west and 

 south-east) blow across the isthmus with considerable force, and 

 carry with them a cloud of sand, which, on a windy day, forms 

 a dense mass, reaching about to the knees of a person walking over 

 the ground. The passage of this moving sand over the stones or 

 jDcbbles lying on the surface wears them away so as to give them 

 sloping sides, and even to bring them to an angle or ridge running 

 along the upper surface, the direction of the longer axis of the stone 

 with respect to the prevailing wind governing the particular form 

 assumed by the worn stone. Where veins of harder material occur 

 in the stones, these are left projecting from the surface, and are 

 sometimes even undercut. 



2. "The Bone-caves of Creswell Crags." — Third Paper. By the 

 Eev. J. Magens Mello, M.A., F.G.S. 



In this paper the author gave an account of the continued explora- 

 tion of these caves, and of the completion of the examination of the 

 Eobin Hood Cave, noticed in his previous communications. Five 

 deposits could be distinguished in the Eobin Hood Cave, namely, 

 when all present : — 



1. Stalagmite, 2 ft. 



2. Breccia, with bones and flint implements, 1 ft. 6 in. 



3. Cave-earth, with bones and implements, 1 ft. 9 in. 



4. Mottled bed, with bones and implements, 2 ft. 



5. Eed sand, with bones and quartzite implements, 3 ft. 

 Variations both in thickness and in character occur in different 



parts of the cave. The surface-soil yielded traces of Eomano-British 

 occupation, such as enamelled bronze fibula, fragments of pottery, 

 &c. The most important discoveries were made in the cave-earth, 

 and chief among these was a fragment of bone, having on it a well- 

 executed outline of the head and neck of a horse, the first recorded 

 discovery of any such work of art in this country. The cave-earth 

 also yielded a canine of Machairodus latidens, hitherto obtained in
