limestone and slate. An iron-stone bed occurs here which is 

 used for pavements, and fragments of the same animal relics 

 are discoverable in it : a great fissure in the cliff developes 

 fossils of a new character, the nature of which does not appear 

 to be determined. 



From the above facts the author infers, that the slate which 

 is prolonged beyond the Plymouth limestone, even as far 

 southward as Whitesand Bay, is not 'primitive : but he re- 

 marks, that he has never perceived animal remains in the slate 

 north of that limestone. 



Extracts were read from letters from Captain Franklin, R.N. 

 and Dr. Richardson, to Dr. Fitton, V.P.G.S. dated 5th of 

 November 1825, at Fort Franklin, on the Great Bear Lake, 

 N. America. Lat. 65° 12' N. ; long. 123° 5' W. 



Capt, Franklin states, that the expedition under his com- 

 mand had been so much favoured by the season of 1825, as 

 to have accomplished some objects which he scarcely hoped 

 to have attained within that time. Of these the most important 

 were his having reached the sea in latitude 69° 29', ancl longi- 

 tude 135° 40'; and being enabled to see the direction of the 

 coast, both east and west from the mouth of the Mackenzie 

 River : — and while he was thus engaged on the Mackenzie, 

 Dr. Richardson went round the northern shore of the Great 

 Bear Lake, for the purpose of becoming acquainted with that 

 part of it to which his course is to be directed in returning from 

 the mouth of the Copper Mine River. — Capt. Franklin gives a 

 general account of the structure of the tract on the course of the 

 Mackenzie, through which he had passed ; and Dr. Richard- 

 son describes the principal physical and geological features of 

 the country traversed by the expedition, — the total distance 

 being about 5 1 00 miles. — The party, at the date of the letters, 

 were established in their winter quarters.
