Abstract
THE INTRA-MERCURIAL PLANET QUESTION.—Notwithstanding the suspicious aspect of the spot remarked upon the sun's disk by Weber at Peckeloh, on the afternoon of April 4, 1876, as it is described by him in his letters to Profs. Heis and Wolf, it would appear that it must be relegated to that class of ordinary solar spots which are better defined than in the majority of cases, and continue visible but a short time. A letter has been addressed to the Abbé Moigno by Señor Ventosa, of the Observatory at Madrid, containing a very definite observation of a spot on that day which was evidently the one noticed at Peckeloh. A similar letter to Prof. Peters is published in Ast. Nach., No. 2106.
