“We have a sufficient number of Trilobites identical with 
those of the Silurian rocks of Europe to institute a comparison 
of the correlation of the ancient ocean in both hemispheres. 
That remarkable and characteristic Lower Silurian form, 
Trinucleus, is among the most common, while Illenus and Iso- 
telus or Asaphus, no less characteristic, are obtained in the 
earliest limestone.”
