The strength and direction of currents appear to be the main agents 
affecting coral growth, though the carriage of food by them is of sub- 
sidiary importance ; “ the growth of corals on the periphery of a bank 
being in great excess of growth in its inward portions, is sufficient to 
explain the formation” of atolls and barrier reefs without Murray’s 
s >lutiou theory ; Bourne (2).
