REPORT ON THE EXPLORATION OE BRIXIIAM CAYE. 521 
: 2. Eleven specimens occurred in the Flint-knife Gallery at distances varying from 1 to 
46 feet from the entrance, and all at depths of from 9 inches to 5 feet in the third bed. 
Amongst these remains are two perfect phalanges, which, though differing somewhat in 
colour, fit together so exactly as to allow little room for doubt that they belonged to 
the same animal, although one was found 10 feet from the entrance at a depth of 3 feet, 
and the other at a distance of 46 feet from the entrance and at a depth of about 5 feet. 
Other bones worthy of note are : — 1. The lower portion of a left humerus with the distal 
articulatory end nearly entire, and measuring in transverse diameter about 3 inches, 
With the least circumference of the shaft 5". The shaft is broken across at about the 
junction of the upper and middle thirds, and the fracture, though ancient, is quite sharp, 
and the bone exhibits no mark of its having been either rolled or gnawed. 2. An 
entire left radius, 12"-6 long, with the proximal end l"-8 X 3 ,,- 25 in the antero-posterior 
and transverse diameters, and the distal 1"‘6 X 2"- 8, with a least circumference of 4"‘5, 
exactly fits the above humerus. As in the former case of the tibia and astragalus, these 
two bones, though found very widely apart, would appear to have belonged to one and 
the same individual. They are both, it should be remarked, deeply impregnated with 
manganesic oxide. 3. A left metacarpal, measuring 8"’5 in length, the proximal end 
l"-35 X 1"‘9, and the distal l"-3 X V‘7, with a least circumference of the shaft of 3"*7, 
and consequently corresponding in dimensions with those of a Horse about 13 hands 
high. The bone, though quite entire, and to all appearance not rolled by water action, 
seems to have been exposed for some time on the surface of, or partly imbedded in, the 
ground, as it is much weather- or sun-cracked, principally at one end. 4. Among the 
remains found in this part of the cavern are a pair of small metacarpals of the right 
side, obviously belonging to the same limb, one of which was met with at a distance 
of 3 feet from the entrance and at a depth of 42 inches, whilst the other occurred at a 
distance of 26 feet and at a depth of 33 inches — affording another instance, of which 
so many are presented in the cavern, of the separation of parts belonging to the same 
animal, which it is reasonable to believe must have been brought into some part of the 
cave whilst still connected by the soft parts. 
3. In the West Chamber two specimens occurred at a depth of 13 feet in the third 
bed, or at the most usual depth for bones in that compartment. They were both marked 
with characters of the greatest antiquity. 
4. In the South Chamber the only equine remains were four teeth, evidently 
belonging to the same animal, though to opposite sides of the upper jaw. The teeth 
are remarkably white, though more or less dendritic.

4 & 5. Bos. 
Remains belonging to the genus Bos are not very numerous, and, with the exception 
of the teeth, most of them are very imperfect. Seven specimens occurred in the Rein- 
deer Gallery, seventeen in the Flint-knife Gallery, and three in the West Chamber.
