represent the old Laurentian and Huronian to which the term 
Archean was applied by Dana. The Basal Complex to which 
Van Hise restricted the name when he introduced the term 
Algonkian, no longer exists. The sedimentary part, with the 
accompanying volcanics, is in this paper called Lower Huronian. 
The eruptive granites and gneisses are at least post-Lower 
Huronian if not post-Upper Huronian in their final consolida- 
tion, and must be included with one or the other. There 
remains nothing below the Lower Huronian to which the term 
Archean is applicable except the theoretical original crust as yet 
undiscovered. On the other hand, the continued application of 
Archean to the rocks known as Huronian and Laurentian, as 
originally given and as subsequently continued by many, would 
seem most appropriate. A. B. WILLMOTT.
