Small Demolished Igneous Bodies along the Western Half of 



the Northern Coast. 



From the cape of Chigasaki'^ (la) at the northwestern end' 

 of the island to the west of Okata"-* (2a), tliere lies along the sea 

 coast a row of hills elevated from the gentle skirt of the somma. 

 The surface of the hills is covered by the somma éjecta of a

Kig. 23. Chigasaki (0) ami Kazabaya (7t), remnants of sma'l 

 igneous bodies along the western half of the. northern coast, now covered by 

 later volcanic materials of the somma, as seen northwards (Fig. 1, la). 



The structure of these demolished igneous bodies as well as 

 their geological relation to the main body of the eomma may be 

 clearly seen on tlie sea cliff where marinf^ abrasion has afforded 

 an excellent opportunity to study them (PL Vl. GA). 



Chigasaki (Figs. 23-26) is an elevated spot, 95 m. above
