Mr R. J. M. Sutherland (F) (Harris & Sutherland): First, I would like to congratulate the authors not only on a very interesting paper but on applying more advanced techniques in masonry construction to one building than I have ever seen before.
Mr C. Tucker (M) (British Railways Board): I would like to contribute two points, one of which is a little out of order in that it is an extension on the scope of the paper, but nonetheless is most relevant and features somewhat novel engineering.
With the development of articulated metal structures during the 19th century and the recognition of statical-indeterminacy, an era of intense interest in labour-saving extremum principles emerged. Outstanding among those principles is that of ‘least work’. It was discovered independently, principally by Menabrea, Castigliano, and Frankel. This paper is concerned with the conceptual contrasts of their work, as being highly instructive. Interesting personal relationships are necessarily included with Cremona’s judgment of Menabreand Castigliano following their notorious dispute within the Academy of the ‘Lincei’. T.M. Charlton
