ABSTRACT ON Thursday, November 12, a small company gathered in the entrance hall of the1 Royal Institution of Great Britain to witness the unveiling of the memorial to Sir James Dewar, who

for forty-six years was director of the Institution. Mr. H. Munro Ross, chairman of the memorial fund committee, described the inception of the fund, and stated that although Dewar himself

wished for no memorial, it was felt that a commemorative plaque in the Royal Institution, his home for so many years, and the scene of some of his best work, would meet with general

approval. Mr. Munro Ross then asked the president of the Royal Institution, His Grace the Duke of Northumberland, to accept the plaque as a perpetual memorial to Sir James Dewar and his work

at the Institution, and to unveil it. The Duke of Northumberland acknowledged the gift on behalf of the Royal Institution and performed the unveiling ceremony, revealing the relief here

illustrated of Sir James Dewar seated before his laboratory bench. Thus Dewar is added to the group of notable men of science connected with the Royal Institution whose memorials grace its

entrance hall, and its position, on the main staircase opposite the entrance, ensures that all comers will see the likeness of one who was not the least of those who have directed its

activities. After the unveiling ceremony, Sir J. J. Thomson gave a brief address on Dewar and his work. He referred to the originality and forcefulness which were characteristic of

Dewar's methods, and also spoke of his genius for devising spectacular demonstrations. In Sir Joseph's view Dewar's greatest achievements were the liquefaction of gases on a

large scale, thus making possible their use as physical agents, and the use of charcoal cooled by liquid air for the production of high vacua. This work has proved to be of fundamental

importance in experimental research on the structure of matter. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS
