il normal Dieuiljer of the gneiss-mica .sclii.st, petrographicallv sc^me- 

 what similar to it. At Kami-Matsukawa, the schists are uearJy 

 horizontal with a clip towards the north at very low angles, and jn.st 

 at the west end of Kami-Matsukawa, a, highly coarse-cryst;dline 

 limestone, about 70 cm. thick, is interhanded Ijetween the grannlitic 

 schist, having the strike W. 20' X. and dip oO' X. E. At Kamadn 

 we meet again with the titanite-ainphibole schist, now witli tlie strike 



X. 40'^ E. and dip X. ^y. 



The line of section, E-F, 1*1. XX^ , fnjni the small hamlet of 

 Kami-Misaka to Ishikawa, is very similar in general features to 

 the sections A-B, and C-D. lUit here only a part of the Gozalslm 

 belt ((t Z) is to be seen, for a distance of not more than ^ km. 

 ill breadth, flanked on either side l)y a granitic ])(jss. Tiie lower 

 memljer of the Takanulcl series is concealed from \ iew in the present 

 line of section, (jwing prolja1)!y to a greit dislocation line, whose 

 s(jiilh('i'n prolongation at the we.>t of Takanuki may be traced in (he 

 last protile ; and this fault has probably brought the u[)per member in 

 direct contact with tiie granite. 



As may be seen from Eig. 8, PI. XXIV, the above mentioned 

 small l)clt of the ( ruzaisho rocks at the east end of the protile, is pinch- 

 ed iu between granites \\ (r and 11 (r, ;(nd conseijueutly tlie mode of 

 arrangement is very much disturbed. Xear a small water-mill at Xaka- 

 Misaka, a tourmaline-ljeai'iug hornblende- sali te sehi>^l (h) of a rather 

 black, massive a])pearance seems to abut against the neck of an 

 amj)hiltole-picrite (d), but the exact relation between them c<.)uld not be 

 made out. Tha peridolite is, ou theea.st, in direct contact with thehorn- 

 bleiide-<irainte, which is itself more or less u'ueissose in structure 

 {gn) near the line of contact. The peridotite is followed, to the west, 

 by I)auds of spotted chlorite-schist, alternating with a garnet- 

 chloritoid-quartz schist (c), said to contain the unique mineral
