The specimens of rocks I obtained have been deposited in the Museum of the Geological Society, and are referred to in the ensuing pages by the numbers affixed to them. The notices are arranged nearly.in the order of the route of the expedition, commencing with Great Bear Lake, where our winter quarters were situated. GREAT BEAR LAKE.
