“pebbles, but under no hypothesis can I admit this to be 
“their origin. They have no particle of exterior covering, no 
“marked evidence of derivation (through denudation or rolling) 
“from any prior deposition of the matrix in which they occur, 
“and are contemporary with the bed in which they occur. 
“The same could not be derived from itself, and no older 
“hardened Oolitic rock or bed, or local unconformity occurs 
‘“‘anywhere; the whole series is one of continuity. Again, 
“you have no distant prior indurated, or hardened rock, 
“from which these rounded, and in places, angular masses 
“could have been derived—each successive bed was deposited 
“upon that below, long before induration or hardening through 
““superincumbent pressure took place—there was nothing (no 
“earlier Oolitic rock) to be derived from. These rounded 
“masses, or lenticular, or angular, or whatever shape they take, 
“are simply segregation of fine Oolitic matter at the time of 
“deposition, in small and shallow pool-like irregularities, in 
“and on the shore at the time of deposition, just as we see 
““now in ripples and ripple marked rocks of modern times, 
“where the small comminuted shells and grains are left in the 
“hollows and irregularities of a long flat shore, their specific 
“oravity being different to the then containing, and Oolitic 
“forming sediments. The Hastern coast of England, Essex, 
“Norfolk and Suffolk show these small irregular indentations 
“filled with small and broken shells and debris left by the 
“returning tide. One part of your specimen shows the extreme 
“thinness and pellicle-like bottom to one of the oval portions 
“so thin as to defy measurement, and none of them are 
“‘ spherical or thick sections, showing them to be mere pellicles, 
“not pebble-like, or rounded accumulations, without being 
“indurated into masses; and that without any external coat- 
“ing could not occur, as it would be partly crystalline or so 
‘indurated as to show origin. Again, where could you obtain 
‘any evidence of derivation ? Those Horsepool beds could not 
“be derived from prior undisturbed beds of their own age; they 
‘“‘are of the same date and hour as the deposited strata in which 
“they occur, being accretions through local and natural causes
