258 : General Notes. [ April, 
the Pacific coast, in the November number of the AMERICAN NAT- 
URALIST. I traversed the same region on my way to Victoria 
last spring, and hope shortly to publish in the Canadian Natural- 
ist a few memoranda made at the time. As you will see by the 
abstract of a paper of mine, read before the Geological Society 
last June {posted with this), I believe it can be shown that the 
glaciation of the south-eastern part of Vancouver Island was not 
accomplished by the glaciers of the interior of the island, as such, 
ut by a great glacier sheet filling the Strait of Georgia, which 
though receiving tribute from the mountains, was fed chiefly by 
the accumulations on the coast range of the mainland, and per- 
haps through its gaps by ice from the central plateau of the 
country. I hope soon to be able to send to you a printed copy of 
the paper referred to, which will make the points on which this 
supposition is based, clear. The north to south glaciation of the 
interior of the province, mentioned in the abstract, I have been 
able to confirm during this season’s exploration, in a number of 
additional localities, and have even found it furrowing the summit 
of an almost isolated mountain at an elevation of over 5000 feet. 
“The original discovery of marine shells in the drift of Van- 
couver Island is due to Mr. H. Bauerman. You will find the mat- 
ter mentioned in the Quart. Journ. Geol. Society, 1859, p. 198; 
also in Dr. Hector’s Report of Explorations in the North-west; 
see also Mr. Dawson’s article in the Canadian Naturalist: ‘ Note 
on some of the more recent changes in Level of the coast of 
British Columbia and adjacent Regions.’ ” 
MICROSCOPY .! 
NEw METHOD OF OpagueE Mountinc.—Mr. C. C. Merriman of 
Rochester, in a recent communication to the microscopical sec- 
tion of the Troy Scientific Association, describes the method of 
preparing his elegant preparations of foraminifera which have 
attracted unusual attention and admiration in the Postal Club, at 
the soirée of the Troy Association, and indeed wherever they 
cover glass, of size to match, is then varnished on one side
