Mr. Richardson contributes a valuable paper on the peninsula of Gaspe, his 

 investigations having had for their object the ascertaining of the precise 

 boundaries of the Lower and Upper Siliuian, and Devonian rocks. 



The Gaspe sandstones are of Devonian age, and contain some remarkable 

 fossU plants ; they rest on the great limestone of Cape Gaspe (probably Upper 

 Sdurian), and this is agam placed uncomformably on the edges of sandstones, 

 conglomerate, limestone, and shale of the Middle and Lower Silurian. 



Mr. Robert Bell, attaclied to the explormg party of Mr. Richardson gives a 

 report on the recent shells which he was instructed to collect. At the Brandy 

 Pots, amongst other shells are recorded Mi/tilus edulis, Mya amiana, 

 Littorina rudis, Buccimm undatum. At other places visited durmg the expedi- 

 tion were taken Pecfen Ishaidicus, SpirorLis naatiloides (?), Soleti ensis, Purpura 

 lapillus. 



While walking through the woods of Hare Island, Mr, Bell observed 

 numbers of Helix liortemis on the trunks of trees and on the leaves of wild 

 grasses. The species, he says, is one well kno^vll to have been imported from 

 Europe ; and the number of vessels from thence which take advantage of the 

 safe anchorage of that place readily accounts for the presence of those snails. 



In speaking of the capeling, which the fisherman there use as bait for cod- 

 fish, Mr. Bell states that the shoals of those fish " are occasionally so dense 

 that the fish on the outside preventing those on the inside from escaping, a 

 fisherman may go in amongst them without a possibility of their getting away, 

 and take them out with a bucket or any other vessel," as Sir William Logan 

 informed him his Indians did in 1845 with a frying-pan, " and in this way 

 obtain bushels of them in a very short time." On such occasions many of 

 them are sometimes thro^ra on the beach by the waves, and occasionally they 

 appeared to Mr. Bell to leap ashore, dying before they could struggle back. 

 "I observed hundreds of them," he says, "lying dead along the margin of the 

 water, and I can readily believe what I have heard, that in some parts they are 

 occasionally found lying in heaps which would contain several bushels mingled 

 with shells, seaweeds, and the remams of land-plants." 



One such heap observed by Sir William Logan measured thirty paces along 

 the margin, while it was a foot deep in the middle and several feet wide, taper- 

 ing away at each end. 



Mr. James HaU adds a valuable paper on Graptolites, to be illustrated by six- 

 teen plates of specimens collected by the officers of the Canadian Survey. Mr. 

 Billings, the palaeontologist of the survey, has nearly thirty pages of the report 

 devoted to his descriptions of the fossils obtained during the expedition, and 

 determined by himself during the previous year.
