Bacteria occur in mud at depths far below where -other organisms are found. At certain places bacteria create conditions inimical to other forms of life but more generally they are beneficial to animal life by serving as food and by mineralizing organic matter.

T.n the summary the following, interesting observations appear: "In some of the samples there its a peculiar assemblage consisting, of larger, shallow wc;terforarninifera, usually much Morn curd broken, accompanied by numerous smaller and well preserved specimens of species known to be characteristic of deeper wad era. This is similar to conditions found to-day about may of -Gne cor=.:L islands of the Pacific Where species l~no-;.n to live in very shallow depths clay be found mix-cd with deeper assemblages.
