Similar privileges have been granted in Europe for transmitting the in- 

 telligence between some of the principal centres of astronomical research 

 in Europe and the eastern ends of the Atlantic cables. 



It is not intended to restrict the transmission of intelligence to the dis- 

 covery of planets and comets, but also to include that of any remarkable 

 solar phenomenon which may suddenly present itself in Europe, and of 

 which observations in America may be practicable for several hours after 

 the sun has set to the European observer ; also the sudden outburst of a 

 star like that in the "Crown" in 1866, together with unexpected showers 

 of shooting-stars, etc. 



To carry out the proposition the following arrangements have been 

 adopted: 



I. 



Centre of communication in the United States 



1. The Smithsonian Institution. JOSEPH HENET, Director. 



Centres of communication in Europe 



1. Greenwich Observatory. Sir GEOEGE B. AIET, Astronomer 



Royal. 



2. Paris Observatory. M. LEVEEEIEE, Director. 



3. Berlin Observatory. Prof. W. FOEESTEE, Director. 



4. Vienna Observatory, Academy of Sciences. Prof. VON LIT- 



TEOW, Director. 



II. 



Telegrams received at the Smithsonian Institution from observers in 

 the United States will be forwarded immediately by Atlantic Cable to 

 Greenwich, Paris, Berlin, and Vienna, and thence by telegraph to other 

 observatories in Europe. 



III. 



Discoveries made in Europe of new comets, planets, etc., will be an- 

 nounced without delay from Greenwich, Paris, Berlin, or Vienna by 

 Atlantic Cable to the Smithsonian Institution, and thence by telegraph 

 to American observatories and the Associated Press. 



IV. 



The telegraphic dispatch announcing a discovery should be as brief as
