The following Communications were read : — 
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 rniie wide, and kaving 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 bays, on each side of which the ground 
is high, and hence the prevailing winds (which are north-west and 
soutk-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 persou walking over 
the ground. The passage of this- moving sand over the stones or 
pebbles 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 
Rev. J. Magens Mello, M.Ä., 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 
Robin Hood Cave, noticed in bis previous Communications. Five 
deposits could be distinguished in the Robin 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. Red sand, with bones and quartzite implements, 3 ft. 
Yariations botli in thickness and in character occur in different 
parts of the cave. The surface-soil yielded traces of Romano-British 
occupation, such as enamelled bronze fibulae, 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 cauine of Machairodus latidens, kitherto obtained in
