An old chapter of the geological record with a new interpretation, or, Rock-metamorphism (especially the methylosed kind) and its resultant imitations of organisms [microform] : with an introduction giving an annotated history of the controversy on the so-called " Eozoon canadense", and an appendix. Paleontology; Metamorphism (Geology); Paléontologie; Métamorphisme (Géologie). INTRODUCTION. Ivii POSTSCRIPTS. A.—'* Eozoon " in loyanite (ante, p. xvi).. con- ,» the Portion of a specimen (highly magnified) of ^^ Eozoon Canadense" with " chamber-casts " (a) in dark green loganite, imbedded in " white pyroxene " or (?) malacolite (b). The last mineral has imdergone in places (a, b) a chemical change (pseudomorphic replacement) into " ferriferous dolomite " —the substance of the "intermediate ; The fine lines are cleavage-divisions : the thick black lines (a) were originally the same; but having become widened into gashes by carbacid solvent action, they are now filled with " ferriferous dolomite ": the irregular-shaped dark spaces (6), enlargements of the latter, are also filled with the same mineral. The loganite is in irregularly rounded crystalloids. Specimens proving the same pseudomorphosis, viz. calcite or miemite after a similar mineral silicate, occur in Connemara, Scandinavia, New Jersey, Ceylon, Vosges, and other places (ante, p. xvii &c.). I I B.—Considering the statements made by Drs. Carpenter, Dawson, and Sterry Hunt as to the "general acceptance " of " Hozoon," it would be a bene- ficial amusement for them to count up, according to the facts given in the preceding pages, how many "scientists " have written in its favour, and how many against it: possibly it will be found that the former are in the minority!.
