Rev. T.W. Webb
May 19, 1885    Hardwick, Herefordshire, England (map)

Like a comet; in a beautiful field, halfway between α and β. H. calls it the richest and most condensed mass of stars in the firmament, and speaks of it as on the W. edge of a vast starless opening [B42] 4° broad; in which, however, I found many minute stars. h., cl. 14 mg. beautiful field. Nearly central, is the strange var., T, which, 1860, extinguished apparently the cl., had almost faded by June 16, and has never distinctly reappeared. In field, f a little n, are two vars. R and S; the whole in singular juxtaposition.

Jan 4, 1781    

Nebula without star, in Scorpius, between the stars g. [now Rho Ophiuchi] and Delta, compared to g to determine its position: this nebula is round, the center brilliant, & it resembles the nucleus of a small Comet, surrounded with nebulosity. M. Méchain saw it on January 27, 1781.
