BY the death of MR. W. A. E. USSHER, which occurred on March 19, many British geologists will lose an old friend who, whether in his usual mood of breezy optimism, or in a rarer phase of boisterous pessimism, was always good company. Mr. Ussher joined the Geological Survey in 1868 and was engaged in the mapping of various parts of England, but his name will always be associated with the Devonian, Carboniferous, and New Red rocks of Devon, Cornwall, and Somerset, where he spent most of his official career. His principal contributions to the literature of these formations appear in the Memoirs of the Geological Survey, in the Journal of the Geological Society, and in the Transactions of the Devonshire Association. In his study of the West Country rocks it was his constant endeavour to secure correlation with their European equivalents, and thus he was brought into close association with many Continental geologists of note. In 1914 he was awarded the Murchison medal of the Geological Society in recognition of his labours. Mr. Ussher retired from the Survey in 1909; unfortunately, ill-health since then kept him in almost complete retirement.
