XLIV. MEETING OF THE AMERICAN ASSOCI- 

 ATION FOB THE ADVANCEMENT OF SCI- 

 ENCE, SFBINGFIELD, MASS., AUG. 

 SSth-SEPT. 4th, 1895. 



In 1859 the American Association as- 

 sembled for its thirteenth meeting in Spring- 

 field. After the lapse of thirty-six years 

 the Association has again met in the metrop- 

 olis of western Massachusetts, this time 

 for its forty-fourth annual gathering, five 

 meetings having been passed on account of 

 the Civil War. 



Geographically, Springfield is well located 



for a place of meeting, being within easy 

 reach of a large proportion of the members 

 of the Association. For some reason, per- 

 haps, the unusually late date of holding the 

 meeting, the hopes of officers and local com- 

 mittee as to attendance were not realized ;, 

 it having been the smallest meeting held irt 

 the eastern section of the country since- 

 that of Saratoga in 1879, and having but 

 slightly exceeded the meetings held in the 

 West. The number of members registered 

 was hardly double that of the earlier Spring- 

 field meeting, when 180 were present. 



The uncertainty until a late date as to 

 where the meeting would be held, it having 

 been hoped that the railroads would make 

 satisfactory rates to San Francisco, may 

 also have contributed to the smallness of 

 the meeting. 



But if the attendance was not what 

 might have been wished, the arrangements 

 by the local committee have rarely been 

 better made. Outside of a University town 

 it is rarely possible to have all the audience 

 rooms in one building, but at Springfield all 

 were in such close proximity that little in- 

 convenience was experienced in going from 

 section to section and to the offices and re- 

 ception rooms. Every convenience was 

 provided for the members, and the courtesies 

 of the citizens of the city are worthy of 

 special mention. It is, however, unusual 

 that the immediate vicinity of the j)lace of 

 meeting is so meagerly represented among
