Nature, March 27th 1873
The largest catalogue of stars that has ever been published
in America is now about to appear from the United States Naval Observatory at
Washington.
This work, as far as we can learn from a recent communication
of Prof. Yarnall, will embody all the valuable observations made since the
foundation of the observatory in 1842, with the meridian instruments,
consisting of the work of the well-known astronomers Coffin, Hubbard, Ferguson,
Newcomb, Hall, Harkness and Yarnall.
Over fifteen years of labour have been devoted to it by Prof
Yarnall and his assistants, and he himself has made nearly one half of the
observations. The catalogue will be based on over eighty thousand observations
of more than ten thousand stars, many of them being quite faint, and in extreme
southern latitudes, such as have never or rarely hitherto been observed.
