19. The various methods of solving frameworks, in which both the degree of mechanical redundancy and the number of independent angular and transverse displacements are small, have been discussed in detail, and it has been shown that there is very little difference in the application of either moment-energy or deformation-energy methods where algebraic solutions are required, and that where arithmetical solutions are sufficient there is a third method available in moment-distribution. The application of special methods such as slope-deflection equations and three- or four-moment equations leads to the same results but by longer processes. E.H. Bateman

THIS Final Report continues and completes the story of the illuminating and exhaustive investigations into the behaviour of steel structures on which the Research Committee have been occupied for over six years.

IN the early days of the Great Western Railway no mention is made of Paddington; in fact, Paddington did not at first enter into the scheme of things. Several sites for a London terminus were considered, including one near Vauxhall Bridge, and another in the old Brompton Road. Raymond Carpmael
