 Diidoma of Honorary Membership by H.R.H. The Prince of Wales, the Vice-Patron. 



Professor Moissan delivered a Discourse at the Rt)yal Institution on " Le Fluor," 

 on Friday Evening, May 28, 1897. In a series of conjoint experiments on the 

 following day with Professor Sir James Dewar, they succeeded in litpiefying 

 Fluorine. And in the year 1903, gaseous Fluorine was actually sent by Professor 

 Moissan from Paris to the Royal Institution, where it was solidified by the use of 

 li((uid hydrogen, and proved even at this low temperature that Fluorine combined 

 with licpiid hydrogen with explosive violence. 



Professor Moissan's last Friday Evening Discourse at the Royal Institution was 

 given so recently as June 1, 19(»G on " L'Ebullition des Corps Simples," wlien 

 he illustrated, by use of his electric furnace, the volatilisation of the metals. 



The Managers desire to offer on behalf of the Members of the Royal Institution 

 the expression of their most sincere syiupathy and heartfelt condolence with 

 Madame Moissan and the family in their bereavement.
