228 PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [Jan. 24, 



[Note, June 29, 1866. — To the foregoing I may now add, that 

 having subsequently examined an extensive series of specimens of 

 Serpentinous Limestones from the . " ^Fundamental Gneiss," sent to 

 me by Dr. Giimbel, I find in some of them the precise parallel as to 

 Microscopic appearances with the most characteristic forms of the 

 Connemara Eozoon ; whilst from these I can trace a continuous gra- 

 dation, through a series of phases which appear due to subsequent 

 metamorphism, to specimens whose characters seem purely mineral. 

 Appearances of precisely the same character are presented by a series 

 of specimens of the Serpentinous Limestones from the " Primitive 

 Gneiss " of Scandinavia, kindly transmitted to me by Prof. Loven. — 

 In a communication I have received from Dr. Dawson, dated March 

 28th, he says : — " I have lately had my attention directed to a point 

 of importance noticed in my paper on Eozoon, but since somewhat 

 overlooked, tlie occurrence of Eozoon preserved simply in Garhonate of 

 Lime, without any Serpentine or other foreign mineral, and showing 

 the structure (that is of the canal-system, for I have not yet seen 

 the fine tubulation) as perfectly, though not so prettily in the matter 

 of colour, as the Serpentinous specimens. This fact alone, which 

 was noticed in my original Paper, and which I have now verified, is 

 of itself a conclusive answer to Professors King and Eowney's objec- 

 tions." *' I may also say that a careful reexamination of the Chry- 

 sotile or fibrous Serpentine, with additional specimens, enables me 

 to reafiirm, if possible with still greater confidence, its entire distinct- 

 ness from any of the structures of the Canadian Eozoon."]
