original names are retained, with the exception of that given to the north 
■ entrance and certain letters indicating the Galleries. 
PLATE XLIII. 
Fig. 1. Section along the Reindeer Gallery from the entrance to the Flint-knife Gallery. 
The original surface line continued sloping to the road. The entrance is here 
represented after the brickwork had been introduced into the first part of the 
fissure f and the finishing of the doorway, s', remaining portions of old 
stalagmite, is from Mr. Pengelly’s section. 
Fig. 2. Section along the Flint-knife Gallery from the Reindeer Gallery to and across the 
West Chamber. The entrance to a short side gallery is shown under m and 
to Munday’s Gallery at and above d. 
Figs. A to G, M M and N N. Sections across different galleries. In the section M M the 
entrance to the Flint-knife Gallery is traced in central outline, and in the 
section N N the entrance to Kelly’s Gallery. The position of the old stalag- 
mite in fig. 1 and the rounded surface of the shingle bed No. 4, in the several 
cross sections, is given on the authority of Mr. Pengelly’s sections. 
The plan and sections were taken by Mr. Bristow, of the Geological Survey, with the 
exception of the lower part of Bed A o. 4 and of the line defining the bottom of the cave 
after that bed was removed. These additions were made by Mr. Bovey of Torquay. 
PLATE XLIV. 
N.B. The figures, with the exception of fig. 13, Plate XLVI., are all of the natural size. 
Fig. 1. Portion of the middle of the shaft of the femur of Rhinoceros gnawed by Hyaena. 
Figs. 2, 3. Upper and lower aspects of the astragalus of Rhinoceros tichorhinus. 
Fig. 4. Outer aspect of the third upper deciduous molar, left side, of Rhinoceros ticho- 
rhinus. 
Fig. 5. Crown surface, in which there is no appearance of the median pit or “ accessory 
valley ” being formed by the fusion of two “ combing ” plates. 
Figs. 6, 7. Similar views of the second upper deciduous molar of the right side, in which 
the same thing is still more plainly shown. 
Figs. 8, 9. Similar views of a less worn third upper deciduous molar of the right side, 
on which no cementum appears to have been deposited. The outer or dorsal 
lamina of euamel is entirely removed. This specimen still more strikingly 
shows the median pit surrounded by a continuous wall of enamel, and that 
the inner lamina of the dorsal enamel plate is continued uninterruptedly from 
one side of the tooth to the other. 
Figs. 10, 11. Outer aspect and crown surface of the first lower premolar, left side (pm 2).
