Abstract

My letter of August 5, 1881, which appeared in NATURE, vol. xxiv. p. 508, stated that a considerable group of sun-spots burst into appearance between 4 and 5 p.m. (about) on July 25, 1881; or more exactly that the new group was absent at 3h. 58m. (i.e. in negative No. 1175), but was present at 4h, 47m. (i.e. in negative 1176), local apparent time; further, that no additional negatives could be taken here until July 30, when the spots had disappeared.
