ROYAL PHYSICAL SOCIETY. 



SESSION CXII. 



Wednesdmj, loth November 1882. — Ramsay H. Traquair, 

 Esq., M.D., President, in the Chair. 



The Chairman delivered the following opening address : 



Gentlemen, — In opening the one hundred and twelfth 

 session of the Eoyal Physical Society of Edinburgh, I must 

 first express the regret which, I am sure, is shared in by 

 every one present, that Professor Archibald Geikie is unable 

 to occupy the chair this evening, and to deliver, in accord- 

 ance with the time-honoured custom of the Society, his 

 address to us as retiring President. But I am also sure 

 that we will all, at the same time, cordially excuse his 

 absence on this occasion. 



Professor Geikie's removal to London, where he is now 

 taking up the duties of the distinguished post of Director- 

 General of the Geological Survey of the United Kingdom, 

 effectually prevents his being present to occupy the chair 

 on this occasion. I am, however, happy to say that we have 

 the bright prospect before us that, before the conclusion of 

 the present session. Professor Geikie will take an oppor- 

 tunity of being present with us, and of then delivering the 

 address which, in the normal course of events, would have 

 been given this evening. 



While we must all rejoice in the recognition of his merits,
