PLATE XXII. 



Microscopic textures of éjecta of the gabbroids, and the cordie- 

 rite-bearing secretionary products or eeramieites erupted in 

 1914, except Fig. 8, which is an. Asama ceramicite of 1913. 



Fi«'. 1. — Gabbroid nuiguifiod 79 diameters. The suiu! éjecta as PI. XXI. 

 Fig-. 5. See pages 11)0, 191. 



l^'g. '2. — Ceramicite or eordierite-bearing éjecta, type I., found at Koike. The 

 corroded anortiiite with a clear gla.'^.sv rim enclosed in large cordierite 

 plates full of minute air-pores. See pages 196, 198, 199, 205. 



Fig. o. — Ceramicite, type IT., under crossed niçois, from Kurokami <»n tJie 

 eastern sjiorc.. \ eordierite crystal in the centre is built up of heteroge- 

 neous grains of the same with homogeneous extinction of light, and 

 pyrrliotite serves as the infilling matter. See pages 196, 19S, 199, 200^ 

 205. 



Fig. 4.— Ceramicite, tyjx* 111., from the same locality as above. A large 

 crystal of cordierite is for the greater part built np of similarly orientated 

 rectangles of the same mineral. See pages 196, 198, 200, 205. 



Fig. 5. — Ceramicite, tyjje IT!., with porphyritic polysyuthetic anorthite, seen 

 under crossed niçois, from the same locality as the two 2)reeediug. See 

 pages 196, 200, 201. 



Fig. 6. — Ceramicite, type IV., from spongy and banded eje;;ta near the Yuno- 

 hira vent on the western side. See pages 196, 202, 205. 



Fig. 7. — Ceramicite, type V., from the same locality as above. It is a com- 

 plex of minute rectangles of cordierite mixed with prismoids of plagio- 

 clase and hypersthene. See pages 196, 202. 



Fig. 8. — Ceramicite, from the volcano Asama, showing corroded anorthite in 

 the ground which is composed of rectangles of cordierite cemented with 

 pyrrhotite, showing cliaraeteristically the so-<.;alled .v'dcronitic texture. 

 Cordierite and pyrrliotite here seem to have crystallized nearly at the 

 same time. See pages 196, 204.
