A compressed cluster under the left shoulder of Pollux; and rather more than one-third of the distance from β Geminorum to β Canis Minoris, following Wasat nearly on the parallel, at about 4°. This was first registered by ♅. in 1783; and was described as a "beautiful cluster of many large and compressed small stars, about 12' in diameter." My telescope only shows a faint mass of very small stars, inclining from sp to nf, but of indistinct figure, the objects being from the 10th to the 16th magnitude. It is No. 458 of H.'s Catalogue; and was carefully differentiated with "Wasat (δ Geminorum).― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
