The granitoid members of the lower series, e. g. syenite and 

 diorites, pass on so as to beard the middle series on the south. 



The middle series is distinct in sections 5, 6, 7. In 5 and 6* it 

 ]s bounded by members of the upper series. In section 8 it is 

 bounded by the upper and lower series. 



Collating the various sections, we find the middle series as con- 

 sisting of — 



1. Jaspideous conglomerate (ash). 



2. Petrosilex. 



3. Quartzite. 



4. Argillites — -red and grey, mixed and separate. 



5. Diorites. 



6. Porphyry. 



7. Syenite. (?) 



In section 2 the series has a width of nearly two miles. From 

 the shore to the red syenite of McNeil's Mountain. In sections 5, 

 t> and 8, the series has a width of about one mile. 



Section 5th. — McDougaW s Mountain to the shore 

 may be regarded as the representative section of this series, as it h 

 characteristic, and as it also exhibits clearly the relation which thr 

 middle series bears to the lower and upper. 



Assuming that syenites or diorites of the lower series lie in the 

 obscure district to the south of McD.ougall% Mountain, as we are 

 warranted to do by the existence of these in similar positions in 

 sections 1, 2, 4 and 8. The sections are as follows : 



1. Syenite or diorite. Lower. 



2. Jaspideous conglomerate (ash), 



3. Petrosilex, 



4. Slates — grey, 



5. Diorite (homogeneous), 



6. Slate— hard, red, 



7. Diorite and porphyry, J
