Volume xiv of the Bulletin has been increased by 38 pages, 
numbered 167-204, which have been published and distributed. 
A brochure entitled “The Organization and Membership of the 
Philosophical Society” has also been printed and distributed. 
The distribution of the publications of the Society and the re¬ 
ceipt of publications in exchange and their distribution to various 
organizations in this city have continued steadily in the manner 
set forth in detail in the annual report of the Secretaries for 
1901. There are appended to this report the following lists: 
1. Of the Bulletins of the Philosophical Society distributed 
from, and received at, the depository in the Smithsonian Institu¬ 
tion during the year. 
2. Of the Bulletins on hand. 
3. Of the separates of Bulletins xi, xii, xiii, and xiv on hand. 
4. A statement of the number of publications received in ex¬ 
change for publications of the Society, these numbers being clas¬ 
sified by countries. 
The following comparison between the present and past will 
serve to indicate whether the Society is in a prosperous and stable 
condition or not. The number of active members has for the 
first time since 1890 increased during the year. The number of 
new members during the year, 11, is also greater than has been 
the case during any one year since 1890. The average number 
of new members per year from 1892 to 1901 was 6. 
The average attendance during the year, 37, is greater than for 
any year since 1890. The percentage of attendance during the 
year, 34, is much larger than for any other of the nineteen years 
covered by the record. The highest percentage of any previous 
year was 27. 
The number of publications received in exchange during the 
year is only 750, as compared with 1,990 during the preceding 
year. The difference is probably due in the main to the fact that 
during 1901 a considerable portion of the receipts were back 
numbers of publications received from establishments with whom 
exchange relations had recently been arranged.
