Description:Excerpt from Africa, Vol. 3: West AfricaExcept near the islands, where coral beds occur, the matter brought up from the bottom during the sounding operations consists mainly of mud presenting little diversity of character. In the shallower sections it contains the remains of globi germes and other animalculac; but in the abysses of over fathoms the frag ments of shells are so minutely ground and altered by the enormous pressure, that it becomes impossible to detect the mingled remains of organisms in this impalpable substance, whose composition is similar to that of chalk. At still lower depths the characteristic deposit is a sort of red clay. The naturalists of the T alisznan have noticed three perfectly distinct colours: a reddish yellow on the Morocco coast, a green in the neighbourhood of Senegal, and a white mud round about the Azores. Thus are being formed strata analogous to those of the upheaved rocks belonging to the successive geological epochs of the earth's crust. Most of these muddy de posits on the bed of the Azorian Atlantic contain volcanic elements, especially pumice, which must have come from the centres of explosion in the archipelagos, as they are met in larger quantity round about the islands containing active craters. Besides these products of eruptive origin, the Talisman has fished up from depths of or fathoms specimens of other rocks, such as granite, gneiss, schists, sandstones and limestones. The cavities of these rocks were for the most part filled with a bluish mud composed chieﬂy of globigerines.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
