Nature October 28th 1875
Rho Eridanus
In the year 1850 the Late Captain Jacob calculated two
orbits for this binary system, the second of which represents very fairly his
subsequent measures to the end of 1857, a rather severe test for elements
founded upon the data available in 1850.
We look in vain for measures later than Capt. Jacob’s though
it may be hoped this and other interesting objects of the southern heavens have
not been entirely neglected of late years. The public observatories are perhaps
too closely occupied with other work to allow much being expected from them in
a class of observation peculiarly suited
to the amateur astronomer, but there must be a grand field of operations for
private observers, in southern double and variable star astronomy.
