120 Dr. FiTTON on the Strata below the Chalk. 



5. Sand, with concretions; greenish grey, uniform, not effervescent. At the 



bottom of this bed is a course of concreted sand passing into stone, with 

 seams oblique to the general stratification. The stone is in some places 

 opake and white, like chalcedony, including however minute dark green 

 particles : the looser pieces are spongy, like the Blackdown whetstone . . 



6. Sand and stone : thus : — 



a. Sand, resembling that of No. 5, but of darker colour 



b. Stone. A dark grey, compact, fine-grained, conglomerate of cal- 



careous spar and grains of quartz, in some places traversed by 

 thin veins of spar 



c. Sand, resembhng a, uniform, not effervescing

In another quarry, immediately beneath this one, the composition was ap- 

 parently the same ; but the beds of chert were more numerous. 



(22.) The false stratification above alluded to, or the subdivision of the 

 beds by lines oblique to the general course of the stratification, is a promi- 

 nent circumstance in the upper part of the lower green-sand in this neigh- 

 bourhood. It is observable in several places on the road from Hythe to 

 London ; and was very well exhibited in the sides of the road through the hill 

 between Sandgate and Folkstone, where the sketch subjoined was taken. 



In the beds, of which a portion is here represented, not only the lines of 

 division, but the concretions within the strata exhibit the oblique arrange- 

 ment; and in some instances, the larger cherty masses, the general direction 

 of which is that of the prevailing stratification, send out offsets in the direction 

 of the false strata, as expressed in the sketch. There is no appearance of
