Mr. BOLTON, presenting the paper, said he would not dwell on the first part of it, nor attempt to deal with the way in which his concept of a method of analysing rigid frames fitted into already accepted methods. The history of science in general over the last 500 years showed that very often new approaches were not so much due to the better observation of facts, better experimental techniques and so on, but rather to a
different viewpoint. He wanted to ofler, not just a method of analysing rigid frames, but a new viewpoint; he asked the meeting to consider the structure as a whole, rather than individual members of it.
