SrECIMBNS PROM LON(i LAKE AM) WKNTWOR'af- Specimon6 from Lon^' Lake, in the colloction of tlio Goolojrical Survey of Canaila, oxliihit wliito crystulline liuuwtoiie with li^rht- green compact or septariiform* serpentine, and much resemble of the serpentine-Uniostones of Granville. Under the micro- scftpe the calcareous matter presents a delicate aroolated appear- ance, without lamination; hut it is not an example of acorvnline Kozoon, but rather of fragments of such a structure, confusedly aggregated together, and having the intei.,..ces and cell-cavities tilled with 8er[)entine. I have not found in any of these fragments a canal-systom similar to that of Eozoon Canarf<'n.'i(', though there are casts of large stolons, and, under a high power, the calcareous matter shows in many places the peculiar granidar or cellular ap- IHiarance which is one of the characters of the supplemental skele- ton of that species. In a few places a tubulated cell-wall is preserved, with structure similar to that of Eozoon mm Fig. 14. Chnraberlots from Long Lake.

Specimens of Laurontian limestone from Wentworth, in the collection of the Geological Survey, exhibit many rounded siliceous bodies, some of which are apparently grains of sand, or small I)ebbles; but others, especially when freed from calcareous matter by a dilute acid, appear as rounded bodies, with rough surfaces, eitlier separate or aggregated in lines or groups, and having minute • I use the term ' septariiform' to denote the curdled appearance so often pre- sented by the Laurentian Please note that these images are extracted from scanned page images that may have
