method by which the glaciers were nourished, and also 

 the relation of relic-glaciers to their original shape and 

 size. Priestley and Wright in their large memoir

 into a comprehensive scheme, and this, with some 

 modifications, the present writer believes to be the best 

 advanced so far.

 classes :
