MS.Add.6145: Poems, in German, English and French, 1836-1843, 78 folios. The text (fo. 4) is preceded by an extract from Goethe's Faust and a list of contents (fo. 2). The poems were possibly intended for publication as a supplementary volume to the author's Verses (Cambridge, 1836), but seem never to have been printed.
MS.Add.6146: Poems and notes, 1836-1840, 128 folios: extracts, laws of various Cambridge societies, including the Theatrical Club, sketches, verses, examples of phonetic script and other material. There are autographs of members of Shrewsbury School (fo. 98) and a letter from Ellis to Mrs Severn (fo. 112).
