Vol.. 6, 1920 INTERNATIONAL ASTRONOMICAL UNION 
353 
eral Secretary of the International Research Council, follows this report 
together with the Regulations of the International Time Commission and 
of the International Central Bureau for Astronomical Telegrams, which, 
were adopted by the Union. 
The number of votes and the relative financial obligations of each ad- 
hering country are fixed by a scale identical with that which governs 
these subjects in the International Research Council. The unit of financial 
contribution for the United States during the first three years of the con- 
vention may not surpass 1,500 francs annually. In this connection we 
should note the fact that, upon the recommendation of the American 
delegates representing Astronomy and Geophysics, the administration 
of the latitude variation problem is to be transferred to the International 
Astronomical Union. The financial obligation of the United States in 
support of this work is one of the larger items entering into the financial 
budget of the Astronomical Union. 
The budget of the Astronomical Union for subsequent years shall be 
determined in a manner precisely parallel to that adopted for the Re- 
search Council. 
The following officers of the Astronomical Union were elected in general 
session : 
President, M. Be;njamin Baillaud, Director of the Paris Observatory. 
General Secretary, Ai.Fre;d FowIvER, F.R.S., Professor of Astrophysics, Imperial 
College of Science and Technology, South Kensington, London.

Dyson, the Astronomer Royal, Greenwich, London; M. Georges Lecointe, Director 
of the Royal Observatory of Belgium, Brussels; M. AnnibalE Ricco, Director of the 
Observatory of Mt. Etna, Sicily.
