  <dc:title>Letter from [Alan Archibald Campbell] Swinton, to The Editor, Modern Wireless</dc:title>
  <dc:description>Acknowledges receipt of a previous letter, returning the drawing [enclosure not present]. Comments that the only criticism he has is regarding the form if the sign of alteration in connection with the frequency of the triode oscillators. As it is drawn, it looks more like the figure "2" rather than a sign for alternating.</dc:description>
