 the Managers at their Meeting held this day, was read and unani- 

 mously adopted : — 



Resolved, That the Managers of the Royal Institution of Great Britain 

 desire to record their sense of the loss the Institution and the Engineering 

 Industry have sustained by the death of Sir Thomas Wrightson, Bart., J. P. 

 D.L. M.Inst.C.E. 



A Member of the Royal Institution for twenty-eight years. Sir Thomas 

 Wrightson served successivelv on the Boards of Visitors (1918-19) and 

 Managers (1919-1920). 



Sir Thomas Wrightson by his business aptitude and spirit of research 

 exercised a beneficent influence on the iron and steel industry, with which 

 he was so closely identified. He contributed many Papers to the Proceedings 

 of various Engineering, Metallurgical and other Scientific Societies. In his 

 Presidential Address to the Cleveland Institution of Engineers he propounded 

 a new theory of hearing, published in a monograph in 1907 on the Impulses 

 of Compound Sound Waves and their Transmission through the Ear. In 

 association with Sir Arthur Keith their investigations resulted in the dis- 

 covery of many new physiological facts supporting Sir Thomas Wrightson's 

 theory. The whole of the Research is embodied in his work entitled 

 " The Analytical Mechanism of the Internal Ear" (1918). A Friday Evening- 

 Discourse on the subject, " The Organ of Hearing from a New Point of 

 View," was delivered by Sir Arthur Keith in 1919. 



On behalf of the Members the Managers desire to express their deep 

 sympathy with the family in their bereavement.
