An open cluster, on the Lady's leg, and nearly in mid-distance from ε towards γ. It is a gathering of large and small stars, with glimpses of star-dust of considerable extent, and irregular figure; but a few of the principal individuals assume a form not unlike that of an hour- glass. There is no particular compression or condensation of the stars to suggest the existence of a central force; yet the group is sufficiently separated to indicate its forming a peculiar system of its own. The mean apparent place was carefully differentiated from δ Cassiopeae.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
