 Supposedly, Adams communicated his work to Challis in mid-September 1845 but there is some controversy as to how.The story and date of this communication only seem to have come to light in a letter from Challis to the "Athenaeum" dated 17 October 1846.However, no document was identified until 1904 when Sampson suggested a note in Adams's papers that describes "the New Planet" and is endorsed, in handwriting not Adams's, with the note "Received in September 1845".
