Eozoön Canadense

Abstract

I HAVE just observed that in your number for December 22 a correspondent revives some of the old but often refuted objections to the organic nature of Eozoön. As the mail closes in a few hours, and I have lectures in those hours, I cannot reply by this opportunity; but shall crave a small share of your space next week to show that the objections stated are unfounded; and to state what is now being done here in further illustration of this ancient and veritable fossil.
