The flattening becomes increased by the margins rising, till finally the central portions are entirely killed by sediment, and a flat sand-strewn area is produced, surrounded by the raised rolled edges of actively dividing zooids which are untouched by sediment. Upon the barrier there is no doubt that injury of the upper zooids, caused by moving particles sweeping backwards and forwards in the.
