The text of the address given by the President, Professor Patrick Dowling, FEng, at the Institution's Annual Dinner at Guildhall, City of London, on 12 May 1995, in response to the toast to the Institution proposed by Lord Williams of Elvel. My Lords, Distinguished Guests, Ladies and Gentlemen, I hesitate to start my speech this evening on a sombre note but at 7 o’clock this morning my wife, Grace, whom many of you know is a doctor, after much agonizing, diagnosed me as suffering from a highly contagious disease and one which is rare in her experience. She attributes this disease directly to my seven months’ service as President and I have to tell you she holds the Institution of Structural Engineers responsible for if. It is, in fact, foot and mouth disease.

Safety in design Mr Rolfe's answer to his own question ‘a man has injured his right leg and uses a walking stick. In which hand should he hold it for maximum relief?’ (Vo1.73 No. 10 May 1995) is, based on experience of a broken leg: He holds the stick in the right hand when standing and in the left hand when walking. When standing, this enables him, if necessary, to take all the load off the injured leg. When walking, the good (left) leg is necessarily clear of the ground half the time. By holding the stick in the left hand in contact with the ground during this time the total load is shared with the bad leg. Trying to do this with the right hand will merely throw him off balance. If the injured leg cannot take approximately half the total load he will have to use crutches. Verulam
