NOTES AND QUERIES.

that found on tlie river, which is a species of limestone ; these had been thrown 
evidently with the intention of striking the animal. I found the fore- and hind- 
foot standing in a perpendicular position ; and likewise the full length of the 
leg below the layer of ashes, so deep in the mud and water that the fire had 
no effect on them. The fore-foot of the animal consists of four toes and a 
thumb ; each toe has five joints, each last joint was armed with a claw, or long- 
nail. The thumb has two joints ; the crown of the foot is composed of four 
bones, joined together, and each connected to a toe. On the top of this is a 
thin round bone, connecting them with the shin bone. The construction of 
this foot shows that it posssessed much power in grasping and holding objects. 
The hind-foot is smaller, and has also four toes, with five joints, but has no 
thumb. The crown is entirely different in construction from that of the fore- 
foot. A few of the teeth appeared to have been broken out by the force of 
the rocks thrown at the head or the animal, and were carried some little dis- 
tance ; so that they escaped in a measure the violence of the fire, and have all 
the appearance of those of a carnivorous animal. The second trace of human 
existence with these animals, I found during the excavation of the Missouri 
Leviathan. There was embedded immediately under the femur or hind-leg 
bone of this animal an arrow-head of rose-coloured flint, resembling those used 
by the American Indians, but of a larger size. This was the only arrow-head 
immediately with the skeleton ; but in the same strata, at a distance of five or 
six feet, in a horizontal direction, four more arrow-heads were found ; three of 
these were of the same formation as the preceding; the fourth was of a very 
rude workmanship. One of the last-mentioned three was of agate, the others 
of blue flint. These arrow-heads are indisputably the work of human hands. 
I examined the deposit in which they were embedded, and raised them out of 
their embedment with my own hands (p. 21-24)." 
I have visited a drift-bed at Aylesford, but have not succeeded in getting 
any flint implements, excepting questionable arrow-heads. Molars and tusks 
of Elephus primigenms are frequently met with, but I have not yet realized my 
desires in respect to weapons, even with the assistance of my boys, whose eyes 
are sharper than my own. I hope, however, to do so. 
In the Charles Museum we have a flint celt of orthodox type, like that 
drawn in the "Geologist," fig. 37, p. 19. This specimen was found at the 
top of the chalk escarpment, above Kit's Coty House, and was lying in wliat 
is termed a "pot-hole," near the surface, and associated with other flints, as 
they are usually seen, in great abundance. The " pot-holes" I believe to be 
caused by the subsidence of the clay and flints into sandpipes of large 
area. I intend visiting this locality again, and if anything worth notice turns 
up, I shall communicate it. — Yours very truly W. H. Bensted, Maidstone. 
Geology of Cadiz. — Sir, — Would you kindly refer me to any books or 
memoirs in which may be found some account of the Geology of Cadiz? — Yours, 
&c., Sebastian Baggs. 
_ We cannot flnd any work descriptive of the Geology of Cadiz. This city is 
situated on the Tertiary beds, which form part of the Guadalquiver basin, as 
may be seen by reference to either Dumont's or Murchison and Nicol's 
Geological Map of Europe. It would be advisable for any geologist visiting 
Cadiz and its neighbourhood to compare the rocks and fossils seen there with 
the description given of those in Grenada and Murcia by Silvertop (" Geological 
Sketch ofthc Tertiary Formation in the provinces of Grenada and Murcia," &c. 
1836J ; and by Ansted (Quart. Journ. Geol. Soe., vol. xv, p. 585, &c.).
