  <dc:description>Asks for [Alan Archibald] Campbell Swinton Esquire's help in obtaining information for a correspondent working in the medical serivce with the Italian Army. The correspondent writes: 'Have you heard anything about a new "Ray" (something about intersecting magnetic fields) which has a different system of selection to the X-ray...to which in fact blood is opaque and bones are transparent?' Asks if Mr. Swinton can shed any light on this subject.</dc:description>
