532 General Monthly Meeting [Nov. 1, 



In the year 1899, Mr. Spottiswoode presented his father's collection of 

 Optical Apparatus, which is unique in containing Polariscopic Prisms and 

 Crystal Sections of quite exceptional value and interest, and which could not 

 be replaced. 



Resolved, That the Managers desire to express, on behalf of the 

 Members of the Royal Institution, their most sincere sympathy with Mrs. 

 Spottiswoode and the family in their bereavement. 



Wilfrid Ward, F.S.A., 

 was elected a Member of the Royal Institution. 



The Special Thanks of the Members were returned to Richard 

 Pearce, Esq., F.G.S., for his Donation of £100 to the Fund for the 

 Promotion of Experimental Research at Low Temperatures. 



Also to Mrs. Hugo Miiller for her Gift of a Microscope, which 

 formerly belonged to and was used by the late Dr. Warren De La 

 Rue, F.R.S., Secretary of the Royal Institution from 1879-1882. 



The Chairman stated that, in view of the depletion of the Staff, 

 owing to the exigencies of the AVar, the Managers had considered 

 whether it would not be advisable to alter the hour of the Friday 

 Discourse from 9 p.m. to 4 p.m. during the Session before Easter. 



Lord Wrenbury made a few remarks on the subject, calling the 

 attention of the Members to the matter for consideration. 



The Resident Professor stated the difficulties in regard to 

 continuing the Friday Discourses at the usual hour, and the necessity 

 for making a change under present conditions. 



The Presents received since the last Meeting were laid on the 

 table, and the thanks of the Members returned for the same, viz. : —
