Norr.—Investigations of economic as well as scientific value are carried on at the 
Astrophysical Observatory, which was established in 1890. The results are among 
the newest and most important developments of astrophysics, and are of such interest 
that every considerable civilized government has organized such establishments in 
addition to and independent of the observatories devoted to the older processes of 
astionomy. It is requested that the sum of $5,000 be added to this appropriation, to 
provide the means for increased operations and for printing.
