A lucid but loose cluster of small stars— principally 9th to 14th magnitudes, preceded by a 6th— on the robe below the right hip of Cassiopea; and it will be caught up, at about one-fourth of the distance, on a line from γ towards ε. It was discovered by Miss Caroline Herschel, in 1783, and described by her brother as a "forming cluster of pretty com- pressed stars." It may therefore be of interest in a future day, on which account it ought to be rigorously and mathematically figured. Indeed, rigidly accurate drawings are among the desiderata of sidereal astronomy. The mean apparent place is differentiated from γ Cassiopeæ.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
