INTERNATIONAL ASTRONOMICAL UNION Proc. N. A. S. 
the conclusion of peace. The Section did not attempt to outUne the form 
of an international organization which would promise the greatest use- 
fulness, but concerned itself largely with the technical work of the proposed 
Union in which the American astronomers would be chiefly interested. 
The Executive Committee was instructed to appoint subcommittees of 
the American Section which should prepare reports upon nineteen promi- 
nent divisions of astronomical research, for presentation at a later meet- 
ing of the Section. The Brussels delegation was selected in part, and the 
Executive Committee was authorized to complete it. 
The delegation was eventually composed as follows: 
W. W. Campbell, Lick Observatory, Chairman; W. S. Adams, Mount Wilson Ob- 
servatory; Benjamin Boss, Dudley Observatory, Albany; Major Philip Fox, Dear- 
born Observatory, Evanston, at that time with the American Expeditionary Forces 
in France; S. A. Mitchell, McCormick Observatory, Virginia; C. E. St. John, Mount 
Wilson Observatory; F. H. Seares, Mount Wilson Observatory; Frank SchlEsinger, 
Allegheny Observatory, Pittsburgh; Joel Stebbins, University of Illinois, Secretary. 
The special subcommittees were in due time constituted, as follows: 
Committee on the Variation of Latitude. — F. B. LiTTELL, Chairman, A. O. Leuschner, 
Frank SchlEsinger. 
It was voted to ask the American Section of the International Geophysical Union to 
appoint a similar committee to confer and make a joint recommendation on the most 
promising method of continuing the variation of latitude work. 
Committee on Standards of Wave-Length. — Henry Crew, Chairman, H. D. Babcock, 
Keivin Burns, W. W. Campbell, C. E. St. John.
