Yes, thank you, Sir ! In my posting of yesterday, I suspected that Bekesy's "material in the cochlear duct" is the Claudius cells and the Hensen cells. Now, for the Hensen cells, an argument similar to that for the TM holds: Bekesy knew them well. The Claudius cells, however, are not mentioned in the index of his 1960 book "Experiments in Hearing". So the hypothesis "material = Claudius cells" still looks not completely crazy to me. Can they be "removed with a fine brush" ? Reinhart. P.S.: Since at the moment the List does not appear to be "overwhelmed", I shall probably permit myself to post one more cochlear-mechanics message (on the stiffness of the human basilar membrane) later today.
