218 EXCAVATIONS AT DEWLISH. 



spicules, and numerous minute black granules. A small 



bryozoan. 



Sample R.M. Section I. Two enclosed flints, the result 



of thermal fracture, were rather more common here than 



elsewhere. 



These flints show no sign of fire, but are probably flaked 

 by violent changes of temperature. Coarse chalk-sand flint- 

 splinters, sponge-spicules, &c. 

 Sample E.M. Section I. 



Fine rusty flint gravel, angular and sub-angular, and large 

 quartz-grains. Insoluble residue highly ferruginous. 

 Sample P.X.W. Section I., containing large yellow flints 



more numerous on N. side. 



Chalk-sand with splinters of flint. 

 From chalk fissure (see folding plan). 



Angular flint-gravel, many flints polished. 



Samples of all these materials may be seen in the Dorset 

 County Museum.

 in company with Mr. Reginald Smith, of the British Museum. 

 The excavations had by that time exposed the greater part 

 of the trench ; but some of the deposits which formerly 

 filled it remained in contact with its walls. The trench

 is covered with gravel, consisting of subangular brown-coated
