southern extremity of Kamchatka where, both in the Pacific and in 

 the Okhotsk Sea, it was again the same as between Copper and 

 Bering Islands (1.0252). 



In the vicinity of Simushir the salinity was notably high (1.0255), 

 falling again on the course between Urupp and Cape Yerimo, Yezo, 

 to the same figure we had observed in the .south central Bering Sea 

 and between Kyska and Copper Islands (1.0253). 



In the Strait of Tsugaru the same density was observed as in 

 the vicinity of Simushir ( 1.0255), but we found it greatly increased 

 in the eastern part of the Sea of Japan (1.0260). 



In Toyama Bay we determined salinities ranging from 1.02 16 

 (in the southern part) to the normal salinity for the eastern part of 

 the Sea of Japan, 1.0260 (in the more northern part). Near Wai- 

 jima we found the same salinity as in the same general region further 

 to the north (1.0261) ; but between Komatsu and the Oki Islands it 

 was considerably less (1.0256), and we noted a further drop in the 

 vicinity of the Oki Islands (1.0255). 



Between the Oki Islands and Hornet Island (Liancourt Rocks), 

 we determined tw r o quite different readings, 1.0252 and 1.0258, while 

 south of Hornet Island and south of Matsushima we found the high 

 density characteristic of the east coast of the Sea of Japan (1.0261 ). 

 Along the Korean coast and in the Korean Strait about Tsu-Shima 

 and Ikki-Shima we found water of a very low density ( 1.0248), which 

 was the same as that previously observed off Cape Asacha, Kam- 

 chatka, and in general comparable to that along the east Kamchatka 

 coast. South of Hirado Island and near Nagasaki the density was 

 greater ( 1.0253), and was the same as that in the south central Bering 

 Sea, between Kyska and Copper Islands and along the southern 

 Kurds, and almost the same as that between the Oki Islands and 

 Hornet Island. South of the Goto Islands and west of Koshiki 

 Island (except in one spot in the former locality wdiere we found 

 a density of 1.0253, or practically the same as that south of Hirado 

 Island and near Nagasaki) the density was 1.0247, or approximately 

 the same as that along the Korean coast and about Tsu-Shima and 

 Ikki-Shima. West of Uji-Shima and south of Kusakaki-Shima the 

 density was about the same as that south of Hirado Island and near 

 Nagasaki (1.0252), and the same as that about southern Kamchatka. 

 South of Tanega-Shima the salinity became much higher (1.0262), 

 reaching about the same figure as in the eastern portion of the Sea of 

 Japan. West of Tanega-Shima it was less (1.0257), an( l °ff Kago-
