SESSION" CXV. 



Wednesday, 18th Novemher 1885. — Benjamin IST. Peach, Esq., 

 F.E.S.E., F.G.S., President, in the Chair. 



The Chairman delivered the following opening address : 



In opening the 115th session of the Poyal Physical 

 Society, it is gratifying to be able to point to its continued 

 prosperity, so clearly manifested by an increasing member- 

 ship, by the energy displayed by the various office-bearers, 

 and in particular by the number of valuable papers contri- 

 buted to the new part of the Proceedings. The last instal- 

 ment of the publications of the Society, containing an address 

 by Dr Traquair on ''Biological Nomenclature" and twenty- 

 five original papers, may be compared favourably with its 

 predecessors in regard to the importance of the work achieved 

 by the Fellows. Such a record shows how various members 

 continue to prosecute their researches in different depart- 

 ments of science with a success which augurs well for the 

 future. I desire, now, to express my gratitude for the 

 honour you conferred on me by appointing me to the pre- 

 sidentship, and for the cordial support I received from the 

 Fellows while performing the duties of the office. It has 

 been a source of pleasure to me to further the interests of this 

 Society so far as it lay within my power, and I need hardly 

 add that its future success will always be dear to me.
