PROCEEDINGS FOR 1906 XXXI 



A publication committee consisting of the officers of the section, 

 Prof. McLeod and Dr. Glashan was appointed. 



With regard to the proposal to invite the various officials of the 

 Meteorological Departments of the Empire to meet in Ottawa in 1907, 

 which proposal was referred to Section III., it is the opinion of the 

 section that before making a recommendation, it is desirable that cor- 

 respondence be entered upon with these officials with a view of settling 

 the most suitable place and time for meeting and the questions to be 

 discussed, and that in the meantime action should be deferred, and Mr. 

 Stupart requested to conduct such correspondence.
