waste of crystalloids of malacolite, in the calcaire saccaroide (hemithrene) 

 of St. Philippe (Vosges), rivalling those in Canadian ophite." 



When speaking of this hemithrene (pp. 51, 52) we omitted to mention 

 that besides the " canal system," there are also present rounded grains or 

 crystalloids of pyrosclerite (a serpentinous mineral), occasionally invested 

 with an abestiform mineral related to, if not identical with, chrysotile ; 

 the investing fibres, usually in contact, are in many places separated by 

 interpolations of calcite (pi. iii, figs. 2, 3), a fact proving them to cor- 

 respond with those of the " proper wall " of Eozoon Canadense. (King 

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

Logan (Sir), W. E. The first announcement in connection 

 with the subject of " Eozoon " was made by the Sir Wm. E. 

 Logan, Director-General of the Geol. Survey of Canada, 

 in his Report of the year, 1858. 



Logan (Sir), Wm. E. Exhibited at the Meeting of the American 

 Association for the Advancement of Science at Springfield, 

 in August, 1859, some Stromatopora-XikQ specimens (noticed 

 in the above Report) from the Grand Calumet and Perth 

 (Canada), which he was "disposed to look upon as fossils."

Logan (Sir), W. E. Report of the Geology of Canada, 1863. 

 In this Report (pp. 48, 49) the discovery of specimens, supposed to be 

 fossils, is noticed as having been made "by Mr. J. M'Mullen, of the 

 Canada Geological Commission, in the crystalline limestone of the 

 Grand Calumet river, Ottawa), which present parallel or apparently con- 

 centric layers, composed of crystalline pyroxene, while the interstices are 

 filled with crystalline carbonate of lime. Dr. James Wilson, of Perth, 

 found loose masses of limestone near the same place containing similar 

 forms — the layers composed of dark green concretionary serpentine, while 

 the interstices are filled with crystalline dolomite. If both are regarded 

 as the results of unaided mineral arrangement, it would seem strange that 

 identical forms should be derived from minerals of such different composi-
