of " Mottled Clay " (e), which is the highest bed seen at the southern end of the south 

 cutting. There are in all three cuttings separated by two short tunnels*. The one 

 above described is the south cutting. In the middle cutting the " Mottled Clay " is 

 overlaid by about 10 feet of " Blue Clay" (/), this again by a " Pebble-bed " (i), which

in one place attains a thickness of 1 5 feet ; then there are grey sands (k), measuring 

 20 feet at their thickest part, and, lastly, about 10 feet of brown and grey laminated 

 clayey sand (I). All the beds dip to the north-west, and the " Mottled Clay," which, 

 with the exception of a small patch (/), is the highest bed of the south cutting, is the 

 lowest of the north cutting, and is, indeed, below the level of the railway, but was 

 exposed when digging for the foundation of the tunnel. Throughout the greater part 

 of the north cutting the "Blue Clay" (/) is found at the level of the railway and is 

 overlaid, not by the " Pebble-bed," but by a white"" Shell-rock " (h), and this by the grey 

 and brown sands seen in the middle cutting (k). In the " Blue Clay " of the north cut- 

 ting there are three basin-shaped beds (g) of a dark carbonaceous clay, the so-called 

 " Lignite-beds." Not far from these, and in some cases within them, were found the 

 bones described in this communication. For a full account of the Park-Hill section 

 reference should be made to Mr. H. M. Klaassen's paper mentioned above. 



The middle cutting has recently been filled in and now forms part of the tunnel.
