Mr. Richardson contributes a valuable paper on the peninsula of Gaspe, his 
hivestigatious havmg had for their object the ascertaining of the precise 
boundaries of the Lower and Upper SUurian, and Devonian rocks. 
The Gaspe sandstones are of Devonian age, and contain some remarkable 
fossil plants ; they rest on the great Imiestone of Cape Gaspe (probably Upper 
Silurian), aud this is again placed uncomfonnably on the edges of sandstones, 
conglomerate, limestone, and shale of tlie Middle and Lower Silurian. 
Mr. Robert Bell, attached to the exploring party of Mr. Richardson gives a 
report on the recent shells which he was mstructed to collect. At the Brandy 
Pots, amongst otlier shells are recorded MijtUus edi/lis, Mya areiiaria, 
Littorina rudis, Buccinnm nndatum. At other places visited during the expedi- 
tion were taken Pedeii Islandicus, Spirorbis nautiloides (?), Solen ensis, Purpwa 
lapillus. 
While walkmg through the woods of Hare Island, Mr. Bell observed 
numbers of Helix hortemk on the trunks of trees and on the leaves of wild 
grasses. The species, he says, is one well known 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 capeUng, 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 gettmg away, 
and take them out with a bucket or any other vessel," as Sir William Logan 
informed him his Indians did hi 1845 with a frying-pan, " and in this way 
obtain bushels of them m a very short time." On such occasions many of 
them are sometimes thrown on the beach by the waves, and occasionally they 
appeared to Mr. Bell to leap ashore, dying before they could struggle back. 
" I observed iiundreds of them," he says, " lyuig dead along the margin of the 
water, and I can readUy 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, aud the remains of land-plants." 
One such heap observed by Sir William Logan measured tliirty paces along 
the margua, while it was a foot deep in the middle and several feet wide, taper- 
ing away at each end. 
Mr. James Hall adds a valuable paper on Graptolites, to be illustrated by six- 
teen plates of specimens coUeeted 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 fossds obtamed during tne expedition, and 
determined by himself duruig the previous year.
