Fi(j. 10. — A general appearance of a polished specimen <>f the spotted 

 green schist, showing numerous "eyes" of felspar (page 100). 

 Drawn to natural size. 



Fi(j. 11. — Crystalloids of epidoie in the spijtted green schist. Forms 

 are various, some are heart-shaped, wliile others are almost 

 elliptical. Asymmetry is the prevalent character of these 

 twinned crystalloids. They are exceedingly minute in size 

 and appear under weak powers as colourless dots, rich within 

 the felspar •"eyes" and in the general mass of the rock 

 (page 104).

Plate III 8c IV. 



In Plates III and IV, an attempt is made to illustrate by 

 means of six profiles the general stratigraphie arrangement of the 

 three divisions of the Sambagawan series, together with the intruded 

 masses of serj^entines and the overlying clasto-pyroxenite and clasto- 

 amphibolite complexes of the Mikabu series. The sections are made in 

 various directions, and nearly at equidistant points, and they all give 

 similar profiles, so the general result arrived at as to the stratigraj)hic 

 order may be considered approximately correct. The genuine crystal- 

 line schists and gneisses have so far not yet been observed in this 

 region. Details are given in the chapter on "Profiles" pp. 119 et seq., 

 so that it is not necessary here to append further explanatory remarks. 



A few Avords, however, need be said in regards to ßg.l, Fl. IV. 

 This is drawn from a polished specimen of an altered gabbro from 

 Minano. The white parts traversed by irregular fissures represent a 

 dull, grayish- white felspar, probably hijtuivnite; while the dark-shaded
