Vice-President’s Address. yA 
in 1886, Mr Hugh Miller gave a preliminary note on the 
classification of the Northumberland members of this group, 
showing in tabular form the classification proposed by the 
late Mr George Tate between the years 1856-1868, that 
proposed by Professor Lebour between 1875-1886, and that 
adopted by himself. The last-mentioned is the one given 
here, which is a reinstatement of all the chief features of 
Tate’s original classification. This Table shows so clearly 
the nature of the rocks comprising this group as developed 
in Northumberland, that any further remarks are quite 
unnecessary. (Table, p. 218.)
