The writer draws attention to the fact of its having been announced 

 that Mr. Sandford had "proved the existence of Eozoon " in the ophites 

 of Connemara, which, according to Sir R. I. Murchison and Prof. Hark- 

 ness, are of Lower Silurian (Cambro-Silurian) age. " In other parts will 

 be found square miles upon square miles of rocks of some geological age, 

 often having inliers of limestone ; yet in them there is no Eozoon Cana- 

 dense, it only being found in a peculiar rock (pseudomorph dolomyte) in 

 this small tract of Lower Silurian rocks, in Far-Connaught." (King and 

 Rowney. An old chapter of the Geol. Rec, p. xxvii, 1881.)

This rock, which is well known to be of Jurassic age, contains all the 

 ^'■Eozoon'''' features — "chamber-casts," " intermediate skeleton," "canal 

 system "and " proper wall ;" and, as in specimens from Canada, the 

 "chamber-casts are occasionally preserved in, besides serpentine, a dark 

 mineral resembling loganite, also white pyroxene or malacolite ! This 

 last mineral occurs in crystalloids which frequently exhibit themselves in a 

 decreted condition internally and externally, the interspaces between them
