PHILOSOPHICAL SOCIETY OF WASHINGTON. 125 



the winter of 1882-83 will be, but the indications are that it will 

 be a medium rather than a severe one, as some have predicted. 

 The past summer having been cold and stormy, a warm winter 

 ought to follow ; and the high pressure during last September was 

 slightly west of the Rockies, while during October it was so far to 

 the West and North as to rest over the Cascade range in Oregon. 

 If it continues west of the Rocky-Mountain range a severe winter 

 is not probable. 



Mr. Henry Farquhar commenced a communication on 



EXPERIMENTS IN BINARY ARITHMETIC. 



The meeting was adjourned at the usual hour, (10 o'clock,) with 

 the understanding that the unfinished communication should be 

 taken up at a subsequent meeting. 



225th Meeting. December 2, 1882. 



The President in the Chair. 



Fifty members present. 



The minutes of the last meeting were read and adopted. 



In accordance with the by-laws of the Society, the President, Mr. 

 William B. Taylor, delivered the annual address.
