  <dc:title>Letter from Alfred Charles Glyn Egerton, to Charles Seymour Wright, regarding a paper 'The Earth's magnetic field in Southern Africa at the epoch, 1 July 1930' by E N Grindley</dc:title>
  <dc:description>Sectional Committee: Not stated [Physics]

The paper has been accepted and the referees believe it contains no information of value to the enemy. Requests opinions on this point however, as the subject would be of use to the construction of British Admiralty Charts for navigation. Are magnetic measurements at sea important for the laying of minefields?
