  <dc:title>Letter from the Post Office Engineering Radio Station, on a paper 'Short period fluctuations in the characteristics of wireless echoes from the ionosphere' by Thomas Lydwell Eckersley and F T Farmer to J D Griffith Davies, Assistant Secretary of the Royal Society and reply</dc:title>
  <dc:description>Would like to know the order number of reference to which their invoice refers.

Royal Society replies (sent 27 August 1941) that there is no reference except the number 'u16/4' and the branch is cited as 'Ed. Branch'. Hopes this information is sufficient.
