PLATE IL 

 I.— This section is about 15 feet in depth, but the disturbance 

 extends to a depth of more than twice that distance ; it is 

 in the great sand pit at Erith. 

 11^., 11^.— Two sections of a gulley, icK) feet apart, in Oldhaven 

 beds ; the radiating lines shew the direction opposite to 

 which the flat surfaces of the pebbles in the circumference 

 are arranged, but in that part marked T, left after the 

 pressure had ceased, they are confused. 

 IV.-The surface gravel of the top of Shooters Hill, shewing the 

 arrangement of the pebbles in relation to masses of clay. 

 Evidence of a feeble Trail rests on the top of all. 

 IV.-A section in the chalk pit adjacent to the brick-earth pit at 

 North End, Crayford. In the lower, B.E., are the brick- 

 earths with abundant fossils, and the old implement factory 

 formerly described by me ; at Ti, is confused land rubbish 

 or Trail, &c., with puddled clay over it. Above that are 

 brickearths, which, a few yards off, are thirty feet thicker ; 

 they contain very few fossils. Over the last, at T the 

 remains of the latest fit of glaciation is shewn by festoons. 

 N.B.— As this section is 40 feet deep, the divisions of the scale 

 are two feet each. 



V.-A section on the north-west side of Shooters Hill, shewing 

 the capping gravel. 



VI.— A section in London clay, west of Eltham. Above the T is 

 excavated the hollows of small rills or rivulets ; pebbles lie 

 in their bottoms, and rain-warp, &c., above. 



VII.-A seAion of the lower part of the river bank of the Old 

 Darenth river, at North End, Crayford, shewing trail 

 of an early fit coming down the bank, the chalk is 

 splintered and crushed, and in places has, in the indurated 

 Bull-head, long and cross fractures. Some of the Trail is 

 becoming swept into gravel. Above, rests some of the 

 fossiliferous brick-earths. 



VIII.— Section in the gravel patch on the top of Strood Hill. 

 T, of uncertain age.
