Tn connection with this I would refer to a fact which I have often previously mentioned, namely, that the Lauion- tian limestones, when destitute of the laminated forms char- acteristic of Eozoon, are nevertheless often filled with small patches showing the minute structures. These I regard as fragments of Eozoon broken up and scattered by the cur- rents. In this case, the remainder of these bands of lime- stone must be composed of fragments of other organisms which not being porous have not been so preserved 1)}' in- filtration as to be distinguishable In the original investi- gation of Hozoon, however, a great numbei- of slices of these fragmental limestones were prepared by Mr. Weston the lapidary of the CJeological Survey, and carefully examined, and though they showed no distinct structui-e except that of Eozoon, L folt convinced, and expressed this conviction in my original description, that these fragments presented such traces of structure as one is familiar with in metamorphosed organic limestones of more modern date.* At Cote St. Pierre there are several layers of limestone and dolomite studded * Especially the finely granular structure a'jovu referred to. \.
