These Meetings last Session were again held in the Mathematical 

 Class Room of the High School, for the use of which from year to year 

 the Society is very greatly indebted to the kindness and generosity of 

 the Directors of that Institution. An extra Meeting was, however, held 

 in the Society's Museum on December 27th, Mr Patrick Geddes having 

 very kindly consented to the expressed desire of the Council to give a 

 short account of his proposed method for " the Classification of 

 Statistics," based upon the preliminary Sciences. 



Your Council desire here to record their great obligation to all the 

 gentlemen mentioned for their valued contribution at these Meetings, 

 and to express their due appreciation of the evident pains taken in the 

 proper illustration of the different subjects. It is to be hoped that this 

 part of the Society's work wiU continue to receive a large share of the 

 attention of the Members and Associates, and that this interest wiU be 

 shown more and more, not only by increased attendance at the 

 fortnightly meetings, but by an augmentation of the number of those 

 who thus communicate.
