The collection consisted of 51 cylinder recordings, of which 50 are extant; the original labelling of the cylinders is Thorbecke Kamerun II. Comments on individual recordings are available, but there are no text transcriptions; the recordings were transcribed and edited by Wilhelm Heinitz (see also correspondence). Transcriptions and analyses by W. Heinitz in Thorbecke (1919). It is only possible to assign the transcriptions to the reels after listening, as the Cameroon I and II collections are not differentiated.contents: traditional songs, musical instruments, language samples
