recommended by the Commission in the fourth. This texte synoptique 
was the work of BriguET, whose arduous labors for the past five years 
thus made possible the revision of the rules of nomenclature by this Con-

north German lowlands, DrupE (Dresden) for the mountainous region 
of central Germany, and Briquet (Geneva) for the alpine reigon.
