24 ON THE POSITION OF THE OBEKMITTWEIDA CONGLOMERATE. 



Of the catching and preserving of newer rocks in inverted or 

 isoclinal folds there are abundant examples in our own Highlands, 

 as well as in the Alps, and I need only refer to the sections drawn 

 by Favre, E,enevier, Heim, and many others. 



In the light of the knowledge gained in Wales, the Obermittweida 

 conglomerate appears to be best referred to a newer series than the 

 gneisses among which it occurs ; to be similar to those gneisses, only 

 in so far as it has derived its material from them ; to owe the 

 deformation of its included pebbles, to the mechanical action of which 

 there is abundant proof in the district, and its mode of occurrence 

 to the faults and folds which accompanied that action.
