410 The late Sir Joseph Presiwich — 



June 27, 1852. — By boat to Grays Chadwell churcli 



stands on gravel over Thanet Sands, which show in the lane below. 

 In a pit at the bottom of this lane and overlooking the marshes the 

 T. Sands are 15 to 20 feet thick, and abound in oviform-shaped 

 bodies (eggs of Molluscs ?). Between Chadwell church and Gun 

 Hill the gravel is very ferruginous and worked in many places. 

 It consists chieflj'^ of rounded Tertiary flint-pebbles, not often broken, 

 some subangular flints, a few quartz pebbles, and subangular 

 pebbles of sandstone or imperfect chert (Greensand?). It caps 

 Gun Hill. 



1852. — To Stoke Newington. Confirmed the fact of an overlie 

 of irregular gravel over a roughly stratified one throughout the 

 district between the Kingsland Station and Tylor's House [in 

 Paradise Eow]. The general section is thus : — 



Brown clayey irregular gravel, chiefly B. [Black Tertiary] pebbles and some 



blocks of sandstone. 

 Eoughly-bedded light yeUow-whitish and ferruginous sand and gravel, witb ■ 



mammalian remains. 



Oct. 29, 1853. — Braintree. In the drift 11 [mile] from 

 Wethersfield on the (Nashes Green) Braintree road, a mass of 

 micaceous sandstone was found in a field, the dimensions of which 

 could not be ascertained. The portion exposed measured about 

 10 to 12 feet across and no edge exposed. A second mass was 

 found in a field \ mile north of Wethersfield. It was a grey 

 limestone, 10 feet were exposed and no edge seen. 



September, 18i9. — Through Bergholt to Stutton 



Beyond Stutton, by the side of the river and forming the base of one 

 of the hills, is the clay-pit in which the bones of Mammalia and 

 shells have been noticed by Mr. Wood : —

The bones were said to have been found in the lowest part of the 

 section.

 Survey, p. 95.] 



1859. — Stutton. The fresh-water deposit commences about half 

 a mile east of Stutton Mill in a low cliff, first of gravel, then of 

 London Clay, and then fresh- water deposit. This then continues for 

 about half a mile, being in part formed of reconstructed gravel and 

 London Clay : —
