Page 330 - The author is inclined to believe thai boring algas have more to do with the formation of lagoons in coral islands than has the solution of the coral-substance by the carbonic acid contained in the water. "It is just in such quiet spots as lagoons that the various boring algae would be expected to grow most favourably, and by their incessant ramificalions lead to the ultimate disintegration of any block of coral, following it even when reduced to fragments.
Page 326 - The entry is made from oospores, zoospores, and by the accidental contact of the parasites whilst perforating algse situated on the wall of the coral ; and the penetration and growth appear to be the combined results of the formation of a soluble bicarbonate of lime by the action of carbonic-acid gas evolved from the growing end of the tubular filament, of the pressure incident to growth, and of the movements of the cytioplasm and the cell-wall. The vegetative life of the parasites is accompanied...
