No. 2.] EOZOON CANADENSE. 115 



Beioes. AYe do not see the value of this commonplace and wordy 

 little chapter, except to illustrate what (at pp. 178, 179) he warns 

 Eozoonal and other naturalists to avoid, namely, time-wasting 

 and immature talk, in which words take the place of ideto^,*- 



Plates xxiii. to xxxiv. inclusive contain carefully drawu figures 

 (coloured) of preparations of the Eozoonal ophitic marble, as 

 thin slices, as etched surfaces, and as separated particles, coni- 

 municated by Drs. Carpenter and Dawson. 



Plates XXXV. to xl. inclusive (excepting one figure) contain 

 enlarged sections of the shell-structure of Polytrema miniaceum^ 

 Cyclodypeus, Nummulina, Colcarina Spengleri, Tinoporus bacu- 

 latus, Orhitoides papyyracea^ Poly stomeU a, and Carpenteria rha- 

 phidodendron. All (except one) of these drawings have been 

 made by the Author himself. 



In none of the preparations of known recent and fossil Fora- 

 minifera here figured does Prof. Mobius see any thino- more 

 than a distant resemblance to Eozoonal structure, which latter, 

 as before said, he regards as inorganic. 



This memoir is a handy resiime of the objections made by 

 anti-eozoonists to the presumed organic origin of the object under 

 notice ; and the plates brought together by Prof. Mobius, with 

 no little labour and skill, are useful as a compendious set of sec- 

 tional figures of Eozoon and many of its more modern relations ; 

 and, though he fails to see their alliance, close as the analogies 

 M'^y be, yet his work is highly useful and praiseworthy ; it is 

 disinterested, straightforward, and conscienciously oflfered for the 

 advancement of knowledge. — Annals Nat. Hist., April, 1879.
