A loose cluster in the Galaxy, on the Unicorn's breast; 15° on a line from β Canis Majoris towards Pollux. It was discovered and registered by ♅. in January, 1785, and is No. 408 of his son's Catalogue of 1830. It is a region of stars extending far beyond the field, with the principal members from the 8½ to the llth magnitudes, curiously studded in pairs and triplets. Between these a certain glow indicates numbers of others still smaller.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
