PROCEEDINGS OF LIGHT-HOUSE BOARD. 137 



[ COPY TRANSMITTED. ] 



TRINITY HOUSE, LONDON, E. C., 



25th June, 1878. 



SIR: I have it in command to request that you will be good 

 enough to convey to the members of the Light-House Board of 

 the United States the high sense which the Elder Brethren of 

 this corporation entertain of the many good services rendered to 

 the science of Pharology by Professor HENRY, your lamented 

 predecessor. 



It was the good fortune of two of the members of this Board to 

 make your late Chairman's acquaintance when on a tour of inquiry 

 and observation in the United States, and the survivor of that 

 deputation, Captain SYDNEY WEBB, has a very cordial recollection 

 of the manner in which Professor HENRY placed the experience 

 of the Department unreservedly at their disposal, and of the ex- 

 tremely courteous way in which he assisted their researches, and 

 indicated the directions in which those researches were likely to 

 bear fruit. 



It is at all times a matter of satisfaction to the Trinity House to 

 remember that its main function is one of such general interest, that 

 its members may count upon fellow-workers wherever maritime 

 civilization exists ; but they trust it may be taken as an evidence of 

 their especial hope that through you, Sir, this friendly intercourse 

 with the Light-House authorities of the United States may be 

 continued ; that they thus desire to record their grateful apprecia- 

 tion of the important contributions to the applied sciences both of 

 Light and of Sound, for maritime purposes, with which the name 

 of Professor JOSEPH HENRY will always.be so honorably associated. 

 I have the honor to be, sir, your obedient servant, 



ROBIN ALLEN, 



Secretary. 

 To the Chairman 



of the Light-House Board of the 'United States.
