Note to page 506 {omitted.) 



Professor Jameson having been requested to examine the specimens of limestone 

 collected on the shores of Lake Winipeg, and in the Cumberland-House district, 

 obligingly sent the following note : 



" The specimens of limestone received from you contain examples of the foUowina^ fossil org;inic remains: 



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



2. L. with orthoceratites 



3. L. with terebratulm. 



4. L. with caryophyllitce. 



5. L. with lingulcB. 



These fossils would seem to intimate that the rock in which they are contained belongs 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."
