Abstract
DOUBLE STARS. (1) p ERIDANI.—In the year 1850 the late Capt. 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 of 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.
