 the plntonic! iluid was so much weaker that the original strata of the Kcdtmcnlnry rocks 

 subjected to its iulliieiioa were Ufl unalil iterated uven up to the plane of contact, and yet 

 v& much {[renter that the substance of the en lire muss, throughout thousands of yard* in 

 thickness, wae melted, re-crystalliied and arranged in Laminae (2), Until these conditions 

 hove been defined and illuslrjijed by farts, it is not unreasonable to suspend ear jud^rnenf, 

 and Id HcUrt* that the tendency of pi u tonic rocks hating- the same in^rcdietttt is gneiss

 enormous bedded nnd hi initiated frpCnllim' masses, as the ffimafayai exhibit, more simply 

 than the theory of mctarrjorpfiiimi as at present developed. 



The Wi of gneiss are no doubt devoid or that regularity which divisional planes possess, 

 and in this rc*pnel resemble strata of dtposilieii , (3} hut it opprnrs to me they are not ona*
