strewed about the floor — some probably the result of acci- 
dent, and others that of conflict and sudden retreat. And 
further, had the caves been used for the purposes of burial 
without cremation, which is the most probable, we ought, in 
that case, to find more human bones to account for, or cor- 
respond with, the number of personal ornaments, unless 
the former have been destroyed by the carnivorous quad- 
rupeds who subsequently inhabited the caves, which is not 
an unreasonable supposition. 
Another conjecture which might be hazarded is this : 
that as we know the Romans worked the lead mines in 
Yorkshire during the first century, pigs of lead having 
been found in this county inscribed (with the Emperor 
Domitian's name) IMP. CAES. DOMITIANO. AVGr. COS. 
VII., might not the human relics have belonged to some of 
these people, who made the caves their temporary places of 
abode, and some of which probably died therein ? Rings, 
armlets, fibulae, and other objects of a decorative nature, how- 
ever, appear ill-suited to persons following such menial 
occupations at that period. I therefore consider Mr. Dixon's 
suggestion as far the most likely, under all circumstances, to 
account for the occurrence of the remains of man and his 
works in these caves. 
In the exploration of the Dowkabottom Cave already 
alluded to, I found in the loamy soil fragments of skulls, jaws 
and bones of the short-horned ox, sheep, and goat. The Molar 
teeth, metatarsal, metacarpal, and coronary bones of the horse ; 
skulls and jaws of the wild boar ; portions of the horns of the 
red deer, one of which is the base of a shed horn, the frontal 
bone of a human skull, the upper extremities of a human 
femur, tibia, and fibula, the right side of a human pelvis, 
a spear head 10 inches in length, two pieces of iron much 
corroded, two specimens of the upper half of the spherical 
head of the femur of some animal cut off perfectly smooth
