of Hor dwell, Hampshire, 9 



green clay of about 4 feet, containing much wood and flags in- 

 tersecting each other at right angles, and also standing nearly 

 perpendicularly, mottled with iron, barren of shells, but in which 

 are found remains of Mammalia. I have an under jaw, much 

 crushed (as indeed are all the remains found here), of Anthraco- 

 therium, and like portions of under jaws of Paloplotherium. 

 This band is followed by a band of white sand, which after about 

 6 inches becomes mixed with green clay for about 2 feet. No 

 shells are met with in either the sand or clay ; but remains of 

 Mammals tolerably well preserved occur in the sand. After 

 these two bands, succeed three, sometimes four layers of iron- 

 stone nodules 6 and 8 inches apart and about 2 inches in 

 depth, which extend horizontally, and are about 2 or 3 feet in 

 breadth. The space between these is filled up by white sand, 

 which contains layers of Paludince and Potamomyce. Associated 

 with these are found Trionyx, Emys, broken jaws of Mammalia, 

 with teeth of ditto, fish vertebrae and bones, and occasionally 

 bird-bones, and very small jaws, but no Crocodile. Remains 

 are not common in these layers of sand, and they are very diffi- 

 cult to work, owing to the ironstone. The most likely time to 

 find anything, is when a very rough sea has washed out the iron- 

 stone, and thus uncovered the beds of sand between. After this, 

 there is a band of sands, which at their top and base are thickly 

 traversed by bands of clay, of a light green colour. There is one 

 rather thicker band of clay, about 18 inches from the top of 

 these sands ; and lying upon this and the preceding layers, are 

 found all the same remains which occur in the sand between the 

 layers of ironstone. In the white sand immediately after this, 

 are found layers of Paludime and seeds (with rarely Planorbis 

 platystoma), of about from 2 to 12 inches thick, which also con- 

 tain Trionyx remains, but no other. The sandy clay which comes 

 after this is productive of all the best bones which are found in 

 this stratum. I have from here a tooth of Anoplotherium com- 

 mune, and a scapula, two tibiae, two humeri, metacarps, &c, 

 which are unnamed, but which I believe to be Anoplotherium ; 

 a series of jaws of Paloplotherium, remains of Crocodile, 

 Trionyx, Birds, and a very large unnamed fish, and Emys. 

 Just before the end of these clays, comes in occasionally a small 

 band of broken shells tinged with iron (and much resembling 

 in substance, only harder, the limestone found at the base of the 

 small band in stratum 1, which contains Serpents' vertebrae, &c. 

 from 2 to 6 inches in depth, in which are found Serpents' 

 and Lizards' vertebrae, teeth of Mammals, jaws of Rodents, fish 

 scales and vertebrae, Crocodile, Trionyx and Emys remains, and 

 occasionally large and perfect bones, such as astragali and carpal
