It is issued by the Berlin
Observatory, at the expense of the government.
The companion of this work, intended for the use of the German
marine, is the "Nautisches Jahrbuch," prepared and issued under
the direction of the minister of commerce and public works. It is
copied largely from the British Nautical Almanac, and in respect
to arrangement and data is similar to our American Nautical
Almanac, prepared for the use of navigators, giving, however, more
matter, but in a less convenient form. The right ascension and
declination of the moon are given for every three hours instead of
for every hour; one page of each month is devoted to eclipses of
Jupiter's satellites, phenomena which we never consider necessary
in the nautical portion of our own almanac. At the end of the work
the apparent positions of seventy or eighty of the brightest stars
are given for every ten days, while it is considered that our own
navigators will be satisfied with the mean places for the
beginning of the year. At the end is a collection of tables which
I doubt whether any other than a German navigator would ever use.
Whether they use them or not I am not prepared to say.
The preceding are the principal astronomical and nautical
ephemerides of the world, but there are a number of minor
publications, of the same class, of which I cannot pretend to give
a complete list.
