An Ordinary General Meeting of the Institution of Structural Engineers was held at 11, Upper Belgrave Street, London, S.W.l., on Thursday, 25th January, 1962, at 5.55 p.m. Mr. F. R. Bullen, B.Sc.(Eng.), M.I.Struct.E. , M.I.C.E., (President) in the Chair. The following members were elected in accordance with the Bye-Laws. Will members kindly note that the elections, as tabulated below, should be referred to when consulting the Year Rook for evidence of membership.

Although it has always been his practice to study developments in structural engineering in Europe and North America, recently the author has had a special opportunity to compare those national standards or codes of practice which are analogous to B.S. 449- The use of steel in building. Some of these specifications are in course of revision at the presentime, but almost all of them have been amended during the last decade. Despite the fact that each succeeding revision tends to lead to greater economy in the use of structural steelwork, it may be stated with reasonable confidence that, with one important reservation, the stipulations in B.S.449 : 1959 do not compare unfavourably with other national standards. The exception relates to the allowable stresses in axially-loaded struts, about which the principal information is contained in Table 17 and Appendix B. G. Bernard Godfrey
