Starting again from Sei-shi-au, already referred to, and 

 going round the south coast along the points of Kan-on-san" 

 and Kô-kaku^\ Basaltic cliffs with underlvino- sandv bed, and 

 sandy coves repeatedly occur as far as A-kau"'. At Sa-kan", a 

 little south of the last-mentioned locality, fuller's earth similar 

 to that of Bako, is said to occur according to Tada and Ishii. 

 Upon the walls of the cliff at the recesses of the coves arc found, 

 attached, according to Saito, apparently recent shells, telling the fact 

 that at no geologically remote period, probably Diluvial, a negative 

 shifting of sea-level has taken place in this tract. We are, 

 however, not informed of the height of the former level, as 

 compared with the present ; but at any rate it is of paramount 

 importance for us to have been acquainted with this movement 

 in view of the fact that on the opposite coast, i.e. on Front 

 Taiwan, there are not wanting evidences tending to prove the 

 neo-ative chau2;e on the shore.
