218 Centenary Commemoration, 1799-1899. [June 7, 



within the century. The end of experiment in research at low tem- 

 peratures had by no means been reached, and perhaps in a few years 

 substances yet unknown and more refractory than hydrogen would 

 have been found which would bring the experimenter to within five 

 degrees of the absolute zero. 



The vote was seconded by Sir George Stokes and carried by 

 acclamation. 



Professor Dewar, in reply, referred in appreciative terms to the 

 part taken in the liquefaction of hydrogen by his assistant, Mr. 

 Lennox. For himself, his chief function had been to get the where- 

 withal to carry on the experiments, and without the assistance he 

 had received from numerous friends they would have been absolutely 

 impossible. 



Diplomas of honorary membership were next presented to Pro- 

 fessor Cornu and Professor Newcomb. 



Sir Frederick Bramwell proposed a vote of thanks to the Duke 

 of Northumberland for the manner in which he had performed his 

 duties as President of the Institution. 



This was seconded by Dr. Mond and supported by Professor 

 Barker, on behalf of the guests from beyond the sea, who, he said, 

 had been royally entertained, listening to lectures such as the world 

 had never before heard, and witnessing experiments such as it had 

 never seen. 



The proceedings ended with the reply of the Duke of North- 

 umberland. 



Professor and Mrs. Dewar gave a Eeception after the lecture 

 in their rooms to the guests of the Institution.
