ELEPHANTS’ AND OTHER BONES IN NORTH WALES. 177 
deposited in the Museum at Oxford. The other and larger head, 
with a tooth and leg bone of the same animal, has been presented by 
Henry Warburton, Esq. to the Geological Society of London. Of 
the remaining tusks of elephants, the largest is in the possession of 
G. Harris, Esq. of Rugby; and the other of J. Caldeeot, Esq. of 
Lawford. These tusks have all of them a considerable curvature 
outward towards the point, like those of the one found entire in the 
ice of Tungusia. By the kindness of Edward Grimes, Esq. another 
enormous semi-circular tusk, from the same place, measuring seven 
feet in length, together with a highly valuable collection of the bones 
of rhinoceros, are deposited in the Oxford Museum*. 
The remains of elephant, which I have mentioned as being found 
in North Wales, in the Yale of Clwydd, and near Dyserth, are 
attended with some peculiar circumstances: they are commonly said 
to occur in a lead mine, and so in fact they do; but it is a lead mine 
of an unusual kind, being conducted in a bed of diluvial gravel, that 
contains pebbles of lead, as the gravel beds of Cornwall, called stream 
works, contain pebbles and sand of tin ore. Extensive lead mines 
of the same kind are worked in North America, between Lake Su¬ 
perior and the Missisipi. It is the only case I know in this country, 
* Many of these latter have been engraved in vol. ii. part i. plate xiv. of Cuvier’s 
Animaux Fossiles, from drawings by Miss Morland. The largest and finest head I have 
ever seen of this species of rhinoceros was sent me from Siberia by J. Prescott, Esq. 
now resident at St. Petersburg; and I have presented it, through M. Cuvier, to the 
Museum of the Royal Garden at Paris, where they had no head of this animal. This 
specimen is engraved in vol. ii. part i. plate xii. of Cuvier’s Animaux Fossiles, and in the 
Philosophical Transactions for 18S2, part i. plate iii. In the British Museum there are 
two heads of the same species, one of which was presented to the late Sir Joseph Banks 
by the Emperor of Russia.
