INTKODUCTION. 



magnified specimen of Eozoon, except in the absence of the con*- 

 necting chamber- walls and of the characteristic structures. A 

 similar rock has been obtained by Mr. Vennor on the Gatineau ; 

 but it is less coarse in texture though equally crystalline, and 

 appears to contain hornblende and pyroxene. These are both 

 Laurentian ; and I consider it not impossible that they may have 

 been organic ; but they lack the evidence of minute structures, and 

 differ in important details from Eozoon. 3 ' These details are, pre- 

 sumably, the " proper wall " and " canal system/' In what do the 

 above specimens differ from the much-cited " Burgess Eozoon " ? 

 The mention of these two specimens is a tardy recognition of the 

 facts, first brought forward by ourselves, but constantly pooh- 

 poohed, notifying the occurrence in rocks of a definite lamination 

 identical with that of "Eozoon" But the literature of the sub- 

 ject hereafter is to contain a new chapter " Imitative Forms re- 

 sembling Eozoon " ! As Dr. Dawson is now becoming acquainted 

 with forms of the kind, there is some hope for the triumph of truth.
