the facts observed can only be explained by the eruptive origin of 
both the ore and jasper, as they make the same formation. : 
ore and jasper show that they are the intrusive bodies by 
their breaking across the lamination of the schists and other 
rocks, by the changes that take place in the latter at the line of 
junction, by horses of schist being enclosed in the ore, by the 
curvature of the lamination, produced by the intrusion of the ore 
and jasper, etc. Not the slightest sign of the plasticity or intru- 
sion of the schists relative to the ore or jasper was seen. ‘That 
the wont lamination of the schist existed prior to the intrusion 
deposition is for part of the asia “Ws known; but whether it is 
or not, it has been taken to bes y the observers quoted in 
the establishment of their theories and they must abide by it. 
The lamination, however ee with many of the well-strati- 
fied rocks adjacent, and in some of these the ore and jasper were 
unmistakably intrusive. The. schabts that retained _well-marked
