some on another), that in part of the Archean (Pre-Cambrian)

L. In your opinion is Eozoon Canadense of organic 
origin ? 
Prof. Dana: "I think not." 
Sir J. W.Dawson: "Yes." 
Dr. Hunt: "Yes." 
Prof. Le Conte : " Doubt it. Have no independent opinion 
on the subject." 
Prop. Irving: "No. Inorganic."

Mr. Walcott: " Yes, probably." 
Prop. Geo. H. Williams : " No." 
Prof. Hitchcock : " No." 
Prof. N. H. Winchell : " No." 
Prof. Wadsworth : " No. It has been proved to be geo- 
logically impossible that it is organic." 
Prof. Emerson : " No." 
Prop. Pumpelly : " No. Seems to me of metasomatic ori- 
gin in every section I have studied." 
Prof. A. Winchell : " Not being an original authority, I 
have felt disposed to rest on the opinions of experts in the lower 
forms of animal life, rather than on those of mineralogists and 
petrographic geologists. I have therefore regarded Eozoon as 
animal in nature." 
Dawson, Hunt, Walcott and A. Winchell are for the 
affirmative, and Dana, Le Conte, Irving, Emmons, G. H. 
Williams, Hitchcock, N. H. Winchell, Wadsworth, Em-
