the sound. The experiment may be made in the lecture-room with 

 the sensitive flame and one of the highest pipes of an organ, but it 

 succeeds better and is more striking when carried out in the open air 

 with a pipe of lower pitch, simply listened to with the unaided ear 

 of the observer. Within doors reflections complicate all experiments 

 of this kind. [R.] 



At the conclusion of the discourse His Grace the Ddke of 

 Northumberland, the President, unveiled a bust by the late Mr. 

 Onslow Ford of Sir Frederick Bramwell, Bart., D.C.L. LL.D. 

 F.R.S. M. Inst. C.E., formerly Honorary Secretary of the Royal Insti- 

 tution, and formally presented it to the members, as a token from the 

 Managers and their friends of their esteem for him personally, and 

 their appreciation of the way in which he had served the Institution. 



Sir James Crichton-Browne having accepted the bust on behalf 

 of the members. 



Sir Frederick Bramwell said he found great difficulty in making 

 any adequate reply. At his age — he was well into his 84th year — 

 many things were denied him, among others the faculty of blushing; 

 otherwise he would not have been able to sit and listen to the lau- 

 datory remarks of the Duke of Northumberland and Sir James 

 Crichton-Browne. The fifteen years he had served as secretary had 

 been years of hard work, but of great enjoyment, for he had been 

 brought into intimate contact with many men whom it was a pleasure 

 and an honour to know. He was glad the bust had been given, for he 

 believed the work of the world was done by average mediocrity 

 pegging on, and it was well to encourage men in that sort of thing. 

 There was one matter which he could not pass over, but of which he 

 could scarcely trust himself to speak. He had anticipated the process 

 of making this bust with horror, but it became an actual enjoyment to 

 sit to the genius and genial man who had made it, and watch the clay 

 growing into a likeness of himself, and the death of Mr. Onslow Ford 

 was to him a source of infinite sorrow.
