36 TRANSACTIONS OF THE PLYMOUTH INSTITUTION. 
the stalagmitic breccia, and the teeth are partly encrusted with 
stalagmite. Extreme height from teeth to crown, 6*25 inches; 
extreme breadth on the interzygomatic line (arrived at by doubling 
the perfect half) 5 inches ; between the outer rims of the orbits 
4*25 inches. Breadth of orbit, 1*63 inches; height, 1*25 inches. 
Breadth of nose at base, *81 inch; height from base to suture, 1*96 
inches. The brow is strongly marked, the forehead receding. 
The height from the upper rim of the orbit to the crown as 
preserved is 3 inches; length of the face, 2*64 inches; length of 
upper lip to edge of alveolus, 1*06 inches. Distance from the 
lower rim of the orbit to the edge of the alveolus, 1*64 inches. 
The left maxillary contains five teeth — the three molars and 
two bicuspids (wholly or partially encrusted with stalagmite), 
with the sockets of the canine and of two incisors. The first 
bicuspid displays a remarkable abnormal feature. The fang has 
pierced the jaw, and grown outside it for a third of its total length 
of one inch. The right maxillary contains the three molars, first 
biscuspid, and four sockets. The molars are strongly tubercular, 
and show no appreciable signs of wear ; and the skull is evidently 
that of a person in early maturity. The full breadth at the back 
of the jaw is 2*5 inches. 
2. Skull (the first found — in loose, outer breccia), with upper 
jaw intact; the left orbit, nasal orifice, and a portion of the right 
orbit. Of the frontal bone the brow only remains. The breadth 
over nasal suture does not seem to have exceeded 4*5 inches; 
length of face, 2*5 inches. Breadth of orbit, 1*44 inches; height, 
1*38 inches. Height of nose, 1*7 inches; breadth, '96 inch. 
The orbit lies rather low ; the distance between its lower rim and 
the edge of the alveolus being 1*56 inches, and having the 
appearance of being still less. Length of upper lip to edge 
of alveolus, 1*125 inches. 
The jaw is 2*25 inches in breadth at the back, and contains ten 
teeth, much worn, not flattened, but sloping from within outwards. 
Those wanting are the canines and incisors. The skull is that of 
a person of mature years, probably a woman. 
3. Skull at base of stalagmitic breccia, four feet from inner end 
of northern chamber (marked C A). Of this only pieces could be 
preserved, including fragment of right ramus of lower jaw ; with 
first and second molars, a little worn, two sockets, and remains of 
two more : external depth of jaw, with teeth, 1*5 inches; without,
