Canada,’ on the evening of Tuesday, May 
21, before a large audience. The various 
sections met for the transaction of business 
and reading of papers. Delegates from 
affiliated literary, scientific and historical 
societies throughout Canada presented their 
reports and many of them took part in the 
deliberations of the Society. 
The report of Council for 1901, presented 
by the Honorary Secretary, Sir John George 
Bourinot, K.C.M.G., historian, besides con- 
taining an account of the business affairs 
of the Society regarding the election of four 
new fellows, the diplomas of fellowship, the 
death of the Queen and the accession of 
King Edward VIL., the associated societies 
and the proposed meeting in Toronto in 
1902, dealt a heavy blow upon the cireula- 
tion of ‘yellow’ journals of the United 
States and in general. The question of 
establishing public libraries, the care of the 
Dominion archives, the Canadian Marine 
Biological Station, Nova Scotian and New 
Brunswick archives, tidal investigations, 
together with the question of publishing 
historical memoirs and diaries received at- 
tention as well as the question of presery- 
ation of places of scenic and historic inter- 
est, including the site of Louisbourg and 
the Plains of Abraham. The report also 
contained biographical sketches of the late 
fellows, Hon. F. X. Marchand and Dr. 
George Mercer Dawson. 
In accordance with a suggestion con- 
tained in the honorary secretary’s report of 
last year, to prepare a record of Canadian 
publications embraced under the several 
sections of the Royal Society, the following 
committee of Section IV., which was ap- 
pointed in May, 1900, reported, viz: For ge- 
ology and paleontology, Dr. H. M. Ami; for 
general zoology, exclusive of entomology, 
Dr. J. F. Whiteaves; entomology, Dr. C. 
J.S. Bethune; botany, Dr. A. H. Mackay. 
By a resolution of the Section the same com- 
mittee was reappointed for the year 1901.

SECTION III.—MATHEMATICAL, PHYSICAL 
AND CHEMICAL SCIENCES.

ress in Acoustics: PRESIDENT Loupon, of the

potash or ammonia is a single chemical 
compound, a mixture, or a ‘solid solution,’ 
with results of experiments. 
The Synehronism of Arctic and Antarctic 
Aurore : Mr. ArTHUR HARVEY. 
Auroral observations of the Belgian 
Antaretic expedition of 1898. Construc- 
tion of a table and an auroral curve there- 
from; identification of this curve with those 
for Canada and the United States. En- 
quiry from Arctowski, meteorologist of the 
Belgica, if other concordances are traceable 
between Aurore Australes and Boreales. 
He entrusts the examination to Canada. 
Detailed scrutiny of the records of these 
countries shows the distribution of aurors 
to be local and that their character varies 
at various points. Negative answers must 
be returned to the questions asked, but close 
examinations of aurors in Canada must be 
made during the several Antarctic expe- 
ditions soon to set out.
