 From Avhat has l)een given of tlie organic remains, it is clear that 

 the limestones are of the Carboniferous age, and the tliick complexes 

 occurring together with the calcareous beds must represent partly or 

 wholly Palaeozoic formations. These Primary strata di]) towards 

 the north-west, and their strike is north-south. The ridge of Yörö 

 ((S40 m.), which is a detached mass of the Suzuka, rises precipit- 

 ously from the plain lielow and forms the western boundary of the 

 lowland of Mino and Owari. 



As may be judged from the direction of the limestone outcro])s, 

 in the rectangular geological map, Section Nagoya, t the whole 

 Primary formation seems gradually to change the strike at the north- 

 west ('(^rner of the ])lain, and the well-known fossil l(X';dity of Akasaka 

 is just at this turning ])oint (PI. XXX.). Afterwards the strike 

 shifts a little to the n<^i'th-east, then east to west, and finally, at the 

 north-east corner (^f ^lino, the Paleozoic beds proceed directly in 

 a north-easterly direction far into the mountainous province of 

 Hida. On the east we find the massive mountains of Mikawa, largely 

 composed of granites in which at times hornblende, at others biotite 

 or moscovite, occurs as prevailing component. The granite, frequently
