red felspar, more or less white mica, small masses of black clay, an- 

 gular fragments of green clay-slate, copper and iron pyrites, and 

 plumbago. In two places at least, fragments of a shell resembling 

 an Or this have been found in this grit. 



L Organic Remains. — Fossil remains are numerous in places; they 

 are often comminuted. The following list includes all in my posses- 

 sion at present from the vicinity of Quebec. Formerly I had others, 

 but they are lost. I am not aware of any published list, perfect or 

 imperfect. I beg to express my cordial thanks to Mr, Salter, of the 

 Museum of Practical Geology, for his great kindness in naming all 

 these fossils, excepting the labrum of a Trilobite, for which I am 

 obliged to Mr. Woodward, of the British Museum.
