THE Clough Memorial Medal of the Edinburgh Geological Society for the years 1943–44 has been awarded to Dr. Murray Macgregor in recognition of his outstanding contributions to the geology of Scotland and in particular of the Scottish coalfields. During Dr. Macgregor's long service on the Geological Survey in Scotland, where he has been in charge since 1925, his main task as a worker and administrator has been connected with the geology of the Scottish coalfield area. In his extensive series of original contributions in this sphere, his presidential address to the Geological Society of Glasgow in 1927, entitled "Scottish Carboniferous Stratigraphy", was an outstanding work. Dr. Macgregor has achieved conspicuous success in organizing increasingly detailed work on Scottish mineral deposits and in promoting close collaboration with the mining and industrial community. He has thus been in a position to give authoritative advice to the Scottish Coalfield Committee, appointed by the Secretary of State for Scotland in 1942, and to make important contributions to this Committee's report, now in course of publication. Dr. Macgregor has also made valuable contributions to the geology of the rocks of the Highlands and of the glacial deposits of central Scotland, and he played a big part in the preparation of the Scottish exhibits for the opening of the new Geological Museum in London in 1935.
