Keport of the Editing and Exchange Committee. 



Gentlemen, — During the past year the publication 

 of the Gaiiadian Record of Science has continued as usual. 

 Three numbers have been issued already, and a fourth 

 is now in press. It has, however, unfortunately, been 

 found to be impossible to issue the several numbers 

 on the dates when they were due, owing to the absence of 

 the Editor from town during the summer months. 



The rule of accepting only papers of merit and as far as 

 possible only original papers for publication has been 

 adhered to and a high standard has thus been maintained. 

 One or two papers which appeared in German periodicals, 

 and which were of especial importance to scientific 

 workers in Canada, have also been translated and 

 published. 



As in past years, a large number of valuable exchanges 

 have been received for the Record and placed in the 

 library. 



Eespectfully submitted. 



Frank D. Adams, 



Chairman.
