Capitaine de Frégate Oudet's paper was presented at an Ordinary Meeting of the Institute held at the Walker Art Gallery in Liverpool on 20 May 1966, with the President in the Chair. The paper was, in the absence of its author, read by the Executive Secretary who also summarized for the meeting the report of the Working Group on Traffic Separation at Sea (see p. 411).

In December 1962, at a meeting of this Institute, I gave an account of the work that had led to the adoption of one-way routes for the Dover Strait. I now have the honour of describing the balance of work effected since that time, or more exactly, since the Eastbourne conference where the decision was made to carry on the organization of converging areas.
