The material in this subseries covers some of Martin Rivers Pollock's visits and attendance at conferences from 1947. The bulk of the material, however, relates to a 1981 Conference on the Common Denominators in Art and Science, University of Edinburgh that Pollock helped organise. This includes an extensive sequence of correspondence with prospective speakers, participants and funding bodies. At Coll-1586/G/1/G.82 are a number of invitations to visit declined by Pollock or for which there is no evidence of acceptance. Pollock visited a number of countries to give specific lectures; this material can be found in section Coll-1586/F, Lectures and Broadcasts. Material relating to symposia organised by the Ciba Foundation can be found in section Coll-1586/H.
