It is, however, remarkable that Messier examined this giant nebula with a 4 1/2 foot Newtonian, and then turned the instrument upon Gamma Andromedae — «qui en étoit fort près» — to compare its light with that of the star, on a beautiful night of August, 1764; but he makes no mention of the duplicity, or contrasted colours, of that lovely star.
