Between St. Patrick street and the Grande allee, and also along the north- 

 western extremity of Parliament square, similar strata occur ; dark brown or 

 black compact bitumino-calcareous splintery shales weathering grayish-white, 

 holding cavities in which Mr. Ferrier has recognized crystals of strontianite 

 arranged in stellate groups and associated with terminated crystels of quartz 

 ("diamonds") and an inspissated substance resembling petroleum. These 

 strata dip at an angle of S. 65° E. (average magnetic), and hold fragments 

 of graptolites, Corynoides calycularis, and also a Discina (undetermined). 

 Measured sections of these exposures have been taken for reference, and 

 serve to connect these beds with those occurring between the drill shed and 

 the Grande allee. 



Between Drill Shed and Grande Allee. — Here, as nearly everywhere in 

 Quebec city, may be seen the upturned and denuded edges of the shaly and 

 calcareo-argillaceous strata for a considerable distance. An artificial section 

 at this point gives an average dip of 55°, S. 20° E. (magnetic), varying from 

 50° at the southern extremity to 58° or 60° as we proceed northward. The 

 strata are somewhat disturbed at the southern end, but are very evenly 

 bedded and contain quite an interesting series of fossils, chiefly graptolites 

 throughout. The presence of iron pyrites in these rocks has stained many 

 of the layers, which present a very rusty appearance. The following is a 

 list of forms (provisionally identified) recognized from this section 45 paces 

 in length : 



Diplograptus angustifolius ; Climacograptus perexcavatus ; 



" foliaceus (?) ; '' confertus (?) ; 



" sp. und. ; Dawso7iia, sp. und.; 



Dicellograptus sextans (?) ; Primitia mundula, Jones.
