PLATE V. 



f - 



Nature-print of Eozoon, showing laminated, acervuline, and fraymental 

 portions. 



This is printed from an electrotype taken from an etched slab of Eozoon, and 

 not touched with a graver except to remedy some accidental flaws in the plate. 

 The diagonal white line marks the course of a calcite vein.
