CANADIAN GEOLOGICAL CLASSIFICATION FOR THE 
PROVINCE OF QUEBEC. 
BY JULES MARCOU. 
Several late publications by Mr. Alfred R. C. Selwyn 1 and Sir 
J. William Dawson 2 call for an exposition of the classification 
and nomenclature used in that part of the Canada Dominion, 
which has been, known successively under the names of “La Nou- 
velle France,” Eastern and Lower Canada and Province of Quebec. 
We shall review only the different resumes published at intervals 
in connection with the issue of “ Geological Maps” and “ Palaeo- 
zoic Fossils,” by the Geological Survey. 
logan’s classification of 1855. 
In August, 1855, Logan published, in Paris, his “ Carte geolo- 
gique du Canada,” with an explanation entitled, “ Esquisse geolo- 
gique du Canada,” written by Mr. T. Sterry Hunt. 
The province of Quebec, with the exception of the vicinity of 
Montreal, and a narrow band extending north of the river St. Law- 
rence from Montreal to Quebec, both of which are referred to the 
Champlain system (Cliazy, Trenton and Utica), is colored as be- 
longing to the Hudson river group and the Oneida sandstone. The 
eastern limit of the province is covered by a large band of Niag- 
ara limestone extending from Gaspe to lake Memphremagog, and 
then crossing through the whole of New England. The original 
Taconic area from the boundary line of Canada to Poughkeepsie 
is colored as belonging entirely to the Hudson river group, with 
spots, now and then, of Trenton and Oneida. 
In the text by Mr. Hunt, in all the “Bassin oriental” — east from 
an anticlinal axis (line), which divides the “ terrain” Palseozoic of 
Canada — we have the lower part of the Hudson river group called
