740 PROF. J. BUCKMAN ON THE MIDFORD SANDS. 
poda-bed at Midford, Sherborne, and Bradford Abbas as sands; and 
it is interesting to mark how persistent they are over a wide area; 
but we must guard against its being supposed that it is always so. 
On the contrary, at Ham Hill, and so far off as Doulting, in Somerset, 
the equivalents of these sand beds with occasional beds of shelly 
oolite will be made up wholly of shelly oolite, so much so as to afford 
thick masses of characteristic oolitic building-stones, for which both 
quarries have for ages been celebrated. 
In order to make this the more clear, we append the following :—
