times composed of vitreous copper and the exterior of copper pyrites, 

 or the reverse ; vphilst a few nodules have been found to consist 

 wholly of vitreous copper, and a still fewer wholly of pyrites. Some 

 portions of the shale give out, on being broken, a most powerful 

 garlic or arsenical odour. 



At the Capes, about ten miles east of Bathurst, the sandstones con- 

 tain thin beds of coal, and the greater part of the plants which ac- 

 companied the paper was obtained from them. The coal is bitumi- 

 nous and stated to burn well ; but the quantity is too small to be 

 worked profitably. On the beach Mr. Henwood noticed enormous 

 quantities of nodular iron-stone, though he was able to discover in 

 situ only a few in one of the beds of sandstone. 



Towards Belle Dune, on the coast of Chaleur Bay, hummocks of ser- 

 pentine, traversed by small veins of steatite and calcareous spar, rise 

 through the sand ; and in a few places beds of sandstone and conglo- 

 merate, assuming a flinty character, are in contact with the serpentine. 

 Some of the strata of conglomerate are displaced or heaved by certain 

 joints ; but other joints traverse the strata without displacing them. 



At Chambers's, near Belle Dune Point, is a quartzose ferruginous 

 limestone, which contains remains oi Favosites polymorpha and other 

 corals. The beds strike about N.E. and S.W., and dip 20° S.E. 



At Dumerisque's on the Ristigouche, near Dalhousie, the western 

 extremity of Chaleur Bay, Mr. Henwood observed a series of strata, 

 extending less than a quarter of a mile in length, and bounded by two 

 trap dykes, beyond which he was unable to detect any traces of the 

 beds. The strike of the strata was nearly N.E. and S.W., and dip 

 from 40° to 50° towards the S.E. 



The following ascending sectional list is given by the author : — 



1. Lowest bed, impure Umestone, containing species of Cyatho- 

 phyllum, Favosites, and Syringopora, also crinoidal remains. 



2. An impure limestone not very well exposed, but it contains 

 Favosites Gothlandica, Producta depressa, Atrypa aspera } 



3. Calcareous shale abounding with Producta depressa, and yielding 

 also a species of Cyathophyllum and of Favosites, likewise Atrypa 

 aspera. 



4. Calcareous shale, distinguished by the author as the Trilobite 

 bed, on account of the remains found in it. In addition to the un- 

 determinable portions of Trilobites, Mr Henwood procured specimens 

 of Producta depressa with fragments of Orthocera and other Testacea. 



r>. Calcareous lower earthy shale, in which Producta depressa and 

 other shells and Crinoidea are stated to be abundant, but corals few 

 in number. 



6. Earthy shale, containing numerous specimens of Favosites, cri- 

 noidal stems, Producta depressa, Leptana euglypha, Atrypa aspera, and 

 several of apparently unnamed species. 



A few other beds much decomposed rest upon No. G, and lime is 

 stated to he apparently more plentiful in them. 



7. Above these the strata are more gritty, and fossils are rare, 

 but the specimens obtained by the author include Atrypa aspera, and 

 obscure traces of vegetable remains.
