similarity, in that they "al.ke repre sentthe greatest extension of the 

 ice-sheet. The Ajionian and the Helvetian are then compared 

 indicating a retreat of the ice-sheet. 



Then the Iowan formation of Dr. McGee which Chamberlin 

 co-relates with the Poland/an with some doubt. 



The Toronto formation correlated with the Neudeckian (?) ; 

 the Wisconsin formation with the Mecklenburgian (?) and the 

 later deposits are compared with the Forestian and Turbarian 

 deposits of Europe. 



These two papers are most interesting contributions to glaciology.

Botany. Rare Manitoba^ Plants. I beg to note the finding 

 of the following plants at Stony Mountain, Man., on August 12th 1895. 



(1) Gerardia tenuifplia, Vahl, var. asfierula, Gray. 



This was recorded from the same locality by J. M. Macoun. 

 Many years ago I noticed it northwestward towards Lake Manitoba. 

 This would seem to confirm the conjecture made in Prof. Macoun's 

 Catalogue that G. aspera of Douglas, should be referred here. 



(2) Bouteloua racemosa. Lag. This grass is very rare in Canada, 

 it was found in the same locality by Mr. Fletcher in 1883 



(j) Pel/cea atroputpurea, Link. On limestone rocks. This is 

 the first record for Manitoba, though there are several for the North 

 West Territories. Rev. W. A. Bur.man, Winnipeg, Man. 



Asplenium Ruta-muraria, L: In the Ottawa Naturalist for 

 November 1892, Dr. T. J. W. Burgess, F. R. S. C, records the first 

 discovery in Canada of this rare fern by Dr. P. J. Scott, of Southampton, 

 Ont., on Flower-pot Island, near Tobermorey, Bruce Co. Out. 



In looking through some botanical specimens collected by the 

 Rev. W. A. Burman, of Winnipeg, at Banff, Rocky Mountains, in June 

 1894, I find some good fruiting fronds of this fern. This is the second 

 locality in Canada so far recorded. J. F. 



Zoology. The Common House Mouse, Mm muscu/us, L. 



Two specimens of a mouse taken by the Rev. J. H. Keen, at Fort 

 Simpson, Northern British Columbia, were forwarded for identification 

 to Mr. S. N. Rhoads, of the Academy of Natural Sciences of Philadelphia 

 Pa., who reports that they are the above species, and, that the capture 

 so far north is of interest. J. F. 



Entomology. Pamphila Peckius, Kirby. This pretty and 

 common little Skipper, of which there is normally but one brood in the 

 year at Ottawa, the butterflies appearing in the latter half of June, has 

 this year been practically double-brooded. During the hot weather we 

 had last September numerous specimens were seen darting about 

 the beds of Phlox Drummondii at the Experimental Farm. In 

 previous years an occasional specimen has been recorded in the autumn 

 but this year the species was abundant. J. F.
