A growing feature of the Society's activities during the past two years has been the number of thematic meetings. Themes have included, ‘State of the Art Seminar: Rates of Deformation’, ‘The State of the Art of Palaeomagnetism’, ‘The Mechanics and Effects of Faulting’, ‘The Role of Gravity in Geological Models’, ‘Use of Stable Isotopes in Geology’, ‘The Crust-Mantle Boundary’, ‘State of the Art: Sandstone Diagenesis’ and ‘Metallogenesis in Mesozoic-Cenozoic Orogenic Belts’. Papers arising from some of these meetings have already appeared in the Journal and the remaining meetings have all generated papers which will appear in future issues. To avoid undue delay in the publication of papers derived from other sources, Council has agreed to publish three extra parts of the Journal for 1977, the extra parts comprising Volume 134. These will be distributed free of charge to Fellows. It is anticipated that the two volumes (133 and 134) for 1977 will together comprise between 900 and 1000 pages in the present format.
Volume 135 (1978) will, in six parts, contain material approximately equivalent to the total published in 1977, but will be of different format. To take advantage of economies accruing from improved technology, Volume 135 will be produced by offset lithography, double column and with somewhat smaller print. This will substantially reduce paper costs and will consequently reduce binding and postage costs. Further savings will result from distribution in plastic wrapping.
The Editorial Board has reviewed the content of the Journal since 1972 and is pleased to note
