Professor Hayman confirmed the invitation from Imperial College for 29th March - 2nd April 1966 (Easter being 10th April). Professor Everitt agreed to intimate these dates to the Colloquium on the Friday morning, and to publicise them as widely as possible in the hope of avoiding clashes.
After discussion it was agreed to explore the possibility of holding the 1967 Colloquium at Swansea or York. The 1968 location was left for discussion at Dundee, with general support for Trinity College, Dublin, in either Spring or Summer.
