the Tertiary, and it may be 

 assumed that the same was 

 tlie case with the basalt flows 

 of the pétrographie province 

 of Eastern Asia inchiding the 

 western half of Ilon-shù in 

 Japan ^\ Secondly, that the 

 land connection of Japan with 

 the conthient was severed at 

 the end of tlie Tertiary, or at 

 the beginning of the Diluvium. 

 Thirdly, that a great epeiro- 

 o-enic movement occurred in 

 Eastern Asia accompanied by 

 an outpouring of basalt, 

 thereb}^ casting a modern 

 aspect over the land in the 

 region concerned. Fourthly, 

 that a part of the Upper 

 Kifoiuj-sang formation is pro- 

 bably of the Tertiary age.

From the eumivXi of Chijang-gl on tlie coast, we went to 

 Ky'ông-jiju via the Ka-na-rlihl (370 ??i), first going southwards over 

 a hilly tract with two passes (the M'ôn-clihi and the Kam-chhi, 301 

 m) for 8 km on the stratified tuftite (the strike N. 20 E., and the dip 

 30 N.W.) witli the typical basalt blocks projecting from tlie cream- 



1) The basalt of this x'etrographical province or comagmatic region frequently contains 

 bypersthene and quartz, and genetically, as it seems to me, is closely related to the san^ikite 

 of Sbikoku, first described by Professor Weinscbenk. X. J. Beilageband VII. S. 148.
