This sub-sub-subseries consists of 14 files relating to Martin Rivers Pollock's work for the Edinburgh Society for Social Responsibility in Science (ESSRS). The ESSRS was established in 1969 and Pollock served on the Committee. Most of the material concerns a 'Teach-in' on Chemical and Biological Weapons (CBW) at Edinburgh University in January 1969. The issue of CBW remained a concern of Pollock's thereafter.
