This same report contains also great additions to our knowledge 

 of the Palaeozoic section. Eleven thousand feet of Cambrian are 

 followed by the great series of Devono-Carboniferous limestones and 

 shales, above which are rocks ascribed to Triassic or Permo-Triassic 

 age. 



The following year appeared McConnell's stratigraphy of the 

 mountains, which has remained to this day the basis of nomenclature.

Another advance made in this year was the correlation by Dawson 

 of the rocks of Vancouver and adjacent islands with those of Queen 

 Charlotte island.
