tends between Harleston and Diss, the latter town and North Lop- 

 ham, and thence to Norwich, Dereham, and Swaffham. In Suffolk 

 it was examined by him at Lowestoft', particularly in the clitt' on 

 the north side of the town, where he obtained the following section: 



Covered slope 15 feet. 



Black sand 1 — 



Red and yellow sand 15 — 



Blue clay, with fragments of chalk, chalk flints, )^ ^^ 



oolite, and lias J 



Red and yellow sand 2 — 



Covered slope 20 — 



65 



In the sea cliff a quarter of a mile north of Southwold, in Suffolk, the 

 clay contains a bed of sand two feet thick ; in the same county he like- 

 wise noticed it near Woodbridge, between Wrentham and Wangford, 

 and near the road from Wangford to Southwold. The localities in 

 Essex mentioned by the author are Maldon, Kelvedon, Braintree, 

 Castle Heddingham near Halstead, Navestock, and Upminster ; in 

 Cambridgeshire, Ely and between Caxton and Arrington ; inHunting- 

 donshire, the districts between Huntingdon and Peterborough and 

 Huntingdon and Caxton ; in Bedfordshire, Castle Hill, G miles east 

 of Bedford ; in Buckinghamshire, the line of the London and Bir- 

 mingham railway, near Fenny Stratford and Leighton Buzzard, 

 where it rests on the lower greensand, and is overlaid by gravel 

 containing rounded fragments of ferruginous sandstone ; in ]\Iiddle- 

 sexthe only localities mentioned are Finchlej^ and Muswell Hill; in 

 Hertfordshire the clay was not noticed by the author, though the 

 gravel abounds with fragments of secondary and other formations. 



A description is then given of the transported rocks either inclosed 

 in the clay or accumulated in beds of gravel. Thej' consist of hard 

 and soft chalk, flints, oolite, cornbrash, lias, sandstones, mountain 

 limestone, mica slate, trap, granite, syenite, porphyry, &c. The 

 principal localities mentioned are the Stags Inn near Diss, the Holy- 

 well and Witlingham near Norwich, Ballingdon Hill near Sud])ury; 

 between Peterborough and Huntingdon and thence to Caxton, also 

 between that place and Arrington ; in Hertfordshire these accumu- 

 lations are said to abound around Buntingford, Hare Street, Puck- 

 cridge, Much Haddam, and Newnham near Baldock : a few specimens 

 occur around Hertford and at Ware Mill, and Wade's Mill, \h miles 

 from Ware. The pits at Muswell are particularly noticed, and tlie 

 collections from them formed by Mr. Wetherell aud Mr. Frederick 

 Pusey ; but the specimens of rocks are said to be not nearly so nu- 

 merous, nor the size of the masses so great as in Hertfordshire, Hun- 

 tingdunsliirc, Suffolk, and Norfolk. 



Besides the smaller fragments two large boulders are described. 



One consisting of granite and computed to weigh a ton and a half, 



lies by tlie road side on the north of the village of Hare Street ; iind 



it is so tlioroughly rounded that the author had great difficulty in
