REPORT ON THE EXPLORATION OF BRIXHAM CAVE. 
V. Notes on the Specimens of the Cave-beds. 
Together with the animal remains, a collection was made of sixty-nine lithological 
specimens to illustrate the character of the several deposits in the Cave, and which 
are numbered in the “ Register ” I. to LXIX. At the request of the Committee I 
examined and described these specimens. I do not consider it necessary to give all the 
details of that description here, as it would involve a repetition of much that Mr. Pen- 
gelly and Mr. Bristow have described. I will confine myself, therefore, to a short 
abstract and summary. 
Stalagmite , Nos. I.-VII., XIY.-XXV., XXX., LXVI.-LXVIII.— 6 to 12 inches 
thick, and white or red. Limestone breccia attached to under surface of some specimens. 
Masses of red and white calcareous spar with some fragments of limestone from the 
Crystal Gorge. Mixed with the calcareous spar are seams of stalagmite. Thin plates 
(4 4 inch) of red earthy stalagmite and calcareous concretions interstratified with the 
Cave-earth (I., II., III., XLY.). 
First Bed — Limestone Breccia , Nos. XXVI., XXXIII.-IV., L., LXV., LXIX. — 
Angular fragments of fallen limestone of various sizes cemented by carbonate of lime, at 
times crystalline, at others white and earthy. An occasional fragment of hone. In 
some specimens from the South Chamber (LXV.) the calc-spar, which has not filled up 
all the interstices between the limestone fragments, assumes nullipore-like forms. 
Second or black Bed, No. LY. — Peaty calcareous earth (or leaf-mould 1) with angular 
fragments of limestone. 
Third Bed— Cave-earth, Nos. XL., XLI., XLIII., XLVII.-VIIL, LII., LIV., LIX., 
LXII. — Reddish loam, or loamy clay, with angular fragments of the limestone fallen 
from the roof, some of a large size. No. XL. shows that it extends to just outside the 
second West Entrance. No. LIX., “found in the third bed in various places,” consists 
of pebbles the same as those composing the shingle bed beneath, with small worn pieces 
of quartz and minute crystals of iron-pyrites (Pengelly), nodules of brown hematite, 
and pieces of cellular calc-spar coated and interspersed with the peroxide of iron. 
Fragments of old stalagmite (Nos. VIII. to XIII.) from the West Chamber and Flint- 
knife Gallery, with rounded gravel attached to the under surface of three specimens. 
Fourth or Shingle bed, Nos. XXVII., XXXI.-II., XXXVI. IX., XLII., XLVI., 
XLIX., LVI., LVII., LXIII. — Pebbles of clay-slate, micaceous and chloritic schist, 
quartz, limestone, siliceous sandstone, red micaceous sandstone, greenstone, and red por- 
phyry, with some peculiar round red calcareous concretions full of bits of white schist, 
a few subangular pieces of quartz and of flints, and occasional angular fragments of lime- 
stone, — all generally in a base of reddish loam, but occasionally of sand. In places the 
shingle forms a red calcareous conglomerate; in others it contains innumerable very 
small flat fragments of schist. The base of the bed (XXXI. & XLVI., Flint-knife and 
Reindeer Gallery) is occasionally cemented by the oxide of iron or of manganese. In the 
West Chamber a few angular fragments of limestone are mixed with the shingle. No. 
XXXIX. was, like XL., found just outside the second West Entrance.
