A draft of “ Principles and Practical Recommendations for Design ” for reinforced concrete was recently circulated to members of the Committee for comment, and an amended version was agreed at a meeting of Commission I, at Paris, on 19th June, 1961. It is anticipated that a completed version will be ready for wider circulation this year, after approval by the full Committee. All reports of research results, the derivations and discussions of new design theories are recorded in Bulletins, which may be seen in the Institution library, together with the draft for Practical Recommendations for Design.

Mr. A. N. PROCTER (Member) Dr. M. R. Horne’s contribution on the elastic stability of pony-type trusses contains many points of interest. He has shown how energy equations may be used to obtain approximate solutions of complex problems. The use of welded tubes for this type of construction is aptly chosen. There is plenty of scope for alternative methods to which brief reference has been made.
The results of two loading tests on underreamed piles in London Clay are given, one of these incorporating special equipment for the separate measurement of shaft and base loads. The settlement results are discussed and show agreement with some previously published figures in the light of accepted elastic theories. Willem W. Frischmann and W. G. Kenneth Fleming
