been informed, down the whole of its western shore." This limestone, he 

 adds, " which extends over a vast tract of country, probably belongs to 

 the great series of limestone formations under the green sand and. above 

 the new red sandstone." In another part* of this Appendix, he states 

 that Professor Jameson, who had been requested to " examine the speci- 

 mens of limestone collected on the shores of Lake Winnipeg and in the 

 Cumberland House district, obligingly sent the following note : — The 

 specimens of limestone received from you contain examples of the fol- 

 lowing fossil organic remains : 



1. Limestone with encrinites. The encrinites are in fragments. 



2. Limestone with orthoceratites. 



3. Limestone with terebratulce. 



4. jjimestone with caryophyllites. 



5. Limestone with lingulce. ' 



These fossils would seem to intimate that the rocks in which they are 

 contained belong to the Mountain limestone formation, by many referred 

 to the transition, by others to the oldest or deepest part of the secondary 

 class of rocks." 



On Franklin's second expedition to the shores of the polar sea, in 

 1825-27, which Richardson also accompanied as naturalist, the party 

 proceeded via Fort William, the Lake of the Woods, Lake Winnipeg and 

 the Saskatchewan, and touched at Dog Head, Stony Point, Cat Head, 

 Broken Canoe Point, Wicked Point, Egg Island and Long Point, in 1825, 

 before reaching the Saskatchewan. Richardson's Appendix (Appendix 

 No. 1 ) to the narrative of this expedition contains a very full and graphic 

 description of the "Limestone of Lake Winipeg." The fossils obtained 

 during this expedition are there stated to have been examined by Mr. 

 Stokes and Mr. James de Carle Sowerby, " who found amongst them 

 terebratulites, spirifers, ynaclurites and corallines,'' but it is nowhere stated 

 where these fossils were collected. The Maclurites is said to belong "to 

 the same species with specimens from Lakes Erie and Huron and also 

 from Igloolik," and to be " perhaps referable to the Maclurea magiia 

 of Lesueur.'' Mr. Sowerby, also, is said to have determined a shell, 

 which occurs "in great abundance in the strata at Cumberland House, 

 about 120 miles to the westward of Lake Winnipeg, to be the Penta- 

 merus Aylesfordii." 



In the early part of Captain Back's Arctic Land Expedition to the 

 mouth of Great Fish River, the party which he commanded entered 

 Lake Winnipeg from Norway House, in 1833, and left by the Saskat- 

 chewan, as Franklin's party had done in 1819. Dr. Fitton, in Appendix
