LX THE ROYAL SOCIETY OF CANADA 
The general plan of the Geodetic Survey contemplates the making 
of triangulations at places where they will be of most immediate use, 
the intention being to extend these local triangulations as opportunity 
offers until ultimately they are connected together and form a whole. 
Geodetic levelling was carried on in Quebec, Ontario, Manitoba 
and Saskatchewan. The total distance levelled during the year was 
893 miles. 
A noteworthy event of the year was the twelfth annual meeting 
of the Astronomical and Astrophysical Society of America which was 
held at the Observatory on August 23, 24, 25, 1911. Five sessions 
devoted to the reading and discussion of papers, to the reports of com- 
mittees and to other business were held. About 35 members of the 
Society, including many of the leading astronomers of the United 
States, were present. Aside from the sessions several social functions 
were arranged, and it is believed that all present thoroughly enjoyed 
themselves. Their appreciation was expressed by unanimous resolu- 
tions of thanks, and their opinion of the work of the Observatory was 
voiced in the following resolution which was unanimously adopted: 
Resolved: That the Astronomical and Astrophysical Society of 
America, assembled at the Dominion Observatory for its twelfth an- 
nual meeting, has examined in detail the work of the Observatory 
and expresses its very favourable opinion of the character of the investi- 
gations carried on in all its departments. This is particularly the 
case with the determination of radial velocity, from which unusually 
valuable results have been obtained by means of a telescope of com- 
paratively small size. In view of the pressing need for such data, the 
Society hopes that a more powerful telescope may soon be provided, and 
one in keeping with the standing now attained by the national observa- 
tory of Canada.
