"Proceeding farther towards the centre the next circle (XIII) in sixty divisions gives forty-eight characters, referring each to a different symbol of those famous sixty-four diagrams of Wen-wang which I have entioned above. But of these forty-eight different diagrams there are six, which go to form the set of eight diagrams, viz., earth, ocean, fire, thunder, wind, and mountains, and which are here given twice, in different locations ; six others, not belonging to the set of eight diagrams, are each given twice side by side.
