Thirdly, a chapter is devoted to a consideration of the minute stractnre exhibited by 

 Eozoon; and this is compared with the structure of recent Forandnifera. The tiftli 

 chapter is concerned with the manner in which Eozoon has been jjreserved, and with a 

 consideration of the processes of fossilization by infiltration in general. In the sixth 

 chapter, the author deals with the successors and contemporaries of Eozoon, with 

 special reference to Archpcosphierina, Stromaiopora, Caicnopora, and Beceptnculiles- 

 Another chapter le devoted to a consideration of the various objections whicli have been 

 urged against the organic nature of Eozoon; and a final cliapter treats of certain specu- 

 lative considerations which may be drawn from the study of this fossil. (Nicholson in 

 White and Nicholson's Bib. p. 95.)

Concludes that the phosphatic material found in these rocks in Canada is of organic 



origin, and has been produced by the agency of marine invertebrates. (Nicholson in

The author gives an account of the nature and arrangement of the strata at Cote St. 

 Pierre, with special reference to the ajjpearance presented by Eozoon as occurring in 

 situ. Numerous chrysotile veins pass through the limestone, but the author concludes 

 that they are altogether subsequent to the fossil in origin. The close resemblance of 

 weathered specimens to ,S'<ro»(«<opor« is insisted upon; and two new forms of /iozoou 

 cana(/fin«e are described as \'a.v. niinor and var. ucervulina- The limestone sometimes 

 contains numerous little globose casts of chamberlets, single or attached in groups, each 

 of which possesses the structure of the "proper wall" of Eozoon. For these the author 

 proposes the name of Arehieosphierinm. (Nicholson in White and Nicholson's Bib. 

 pp. 95, 96.)

The author gives general description and illustration of Eozoon canadenne, and also 

 Foraniint/era, from Cretaceous rocks. He advocates the organic origin of Eozoon.
