The greater part of the voluminous correspondence and the file of documents in this series is devoted to work carried out under Zuckerman's direction on behalf of the Sub-Committee. This research focussed on investigating the capacity of dogs to detect buried explosives. The experiments themselves were designed and supervised by Drs J.T. Eayrs and E.H. Ashton of the Department of Anatomy, Birmingham University.
File SZ/MOS(2)/4 consists of an account of a visit made by Zuckerman to the United States in 1952 to meet researchers conducting similar experiments there.
