Total, rain on 66 days, 27-80 in.,—which is a larger quantity 
than common, as the following statement will show.

Comparing one rainy season with another, a greater difference 
appears. ‘The winter of 1850-51 furnished but 7:31 in., that of 
51-52, 18-00 in., that of 52-53, 33-46 in., that of 53-54, 22-93 
in., and that of 54-55, 24-10 in. 
There was some hail in January, and again in December, but 
ho snow. For a few days in each of these months the Coast 
Mountains in the SE were seen to be covered with snow. 
The clouds were sensibly electrified five times—twice in April, 
Once in August, once in September, and once in December. The 
lightning or thunder was distinct except in December when there 
Was a regular thunder-gust with heavy thunder. ; 
n the evenings of the 11th and 12th of August shooting 
Slars were numerous, and still more so on the evening of Decem- 
ber Lith. Nothing extraordinary was observed in November, 
about the anniversary of the great meteoric shower in 1833.

Arr. XXXII—On the Geology of the Hudson’s Bay Territo- 
ries, and of portions of the Arctic and Northwestern Regions 
of America ;* by A. K. Ispisrer, M.A., M.R.C.P. &c. 
In Submitting to the society a Geological map of this extensive 
region, with a few explanatory remarks, my object has been to 
recapitulate very concisely the various observations of the geolo- 
8ists and travellers who have explored, and of the naturalists who 
ve examined the organic remains of this portion of the Ameri- 
can Continent, and to present as completely as possible the results 
Which have been hitherto attained in the study of its geological 
formations. The numberless difficulties inherent in such an un- 
tlaking, embracing a range of country so vast and so difficult 
to explore, or even to obtain access to, must necessarily render 
ay attempt of this nature very imperfect; but I have been
