An irregular but pretty rich cluster, on the weapon arm of Perseus, and in a fine vicinity. It was discovered by H., and consists of individuals from the 9th to the 15th magnitudes, preceded by some largish outliers, one of which is of a red tinge [HD 14398?]. The mean apparent place depends, by differentiation, on α Persei; and it may be fished up about 10° np that star, nearly in the mid-distance of a line shot from Polaris to the west of Algol. A 7th magnitude in the np quadrant is the avantcourier of this field [HD 15497], and three of the llth magnitude form so correct a line in the nf as to attract attention.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
