January 3, 1973 To the Editor of Pensée Portland, Oregon In the May 1972 issue of Pensée (page 29) you mentioned a radiocarbon date of palm kernels and reeds from Tutankliamen’s tomb. Unfortunately you did not mention the literature reference. We looked at the British Museum data in Radiocarbon but could not find it. We should be very glad if you could give us the exact reference   Yours truly,   G.
