FOR the address on vibrations in bridges which I have the honour to deliver this morning, limitations of time preclude any attempt at a comprehensive treatment of the subject, and all I shall aim at is to bring to your notice, without any attempt at proof, one or two rational formule for predicting vibrations in railway bridges, formula which, being rational in contradistinction to empirical, bring into prominence the fundamental principles involved and indicate directions in which further knowledge is required. Professor C.E. Inglis

Dr. J. S. HALDANE, F.R.S., complimented Sir Henry on an admirably intelligible and scientifically correct account of the subject. He claimed that perhaps he was the oldest friend of Sir Henry in the morn, because they were students together in Scotland many years ago. They had gone their different ways in the world, but the problem of compressed air sickness had brought them together again, first in New York and later in this country.
