XX INTRODUCTION. 



In these ee Notes " Dr. Carpenter declares that he is " prepared 

 to maintain the organic origin of Eozoon on the broad basis of 

 cumulative evidence afforded by the combination, in every single 

 mass, of an assemblage of features which can only be separately 

 paralleled elsewhere, and in the repetition of the combination 

 with the most wonderful exactness over areas of immense 

 extent" (will be further noticed, A.D. 1869).

The author makes known the occurrence in beds of serpentine 

 marble in Bavaria of eozoonal structures, certain of which he 

 considers to represent a new species " Eozoon Bavaricum." 



We noticed in our memoir, last considered, as proving the 

 mineral origin of ' ' Eozoon," the presence in various calcitic 

 marbles (hemithrenes) in Scandinavia, Isle of Tyree, New 

 Jersey, of rounded crystalloids of pargasite, chondrodite, horn- 

 blende, &c. Dr. Giimbel declares " there can scarcely remain 

 a doubt that the curiously rounded grains imbedded in the 

 crystalline limestones of Pargas represent the casts of sarcode- 

 chambers, as in Eozoon ; and that they are consequently of 

 organic origin." (See translation of the paper in ' Canadian 

 Naturalist/ Dec. 1866.) This point will be further noticed 

 hereafter.

f ' With reference to the occurrence of serpentine in connexion 

 with the limestones of the metamorphic series of Connemara, 

 this has of late become a matter of some interest, in conse-^ 

 quence of the statement that these deposits afford the Eozoon 

 Canadense. . . . The supposed organic portions of the serpen^ 

 tinous limestones of Connemara do not result from animal
