Section B. Indeed, the last labour of his life, his work ' On the Ratios 

 One to Another of the Atomic Weights of the Elements/ Chapter I of 

 which, " The Glucinum Family," was printed only a few days before 

 the Aberdeen Meeting of 1885 — was done with a special view to its 

 consideration by the members of the Association. At what cost he went 

 to Aberdeen, in September, 1885, none but the few friends who saw him 

 there can realize. But he had never missed one of the meetings of 

 the British Association since he first attended with Mrs. Weldon in 

 1865, and nothing could shake his resolve to go. So, though over- 

 whelmed with work and fall of bodily pain, he hurried from 

 Germany, and, disregarding the remonstrances of his friends, went 

 straight on to Aberdeen ; but only to break down completely on 

 arriving there. After remaining for eight days a prisoner in his 

 hotel, he determined to return alone to his home in Surrey. There 

 he arrived on the 16th September, in such a condition as to inspire 

 the gravest alarm in his friends. Much too late, he now sought that 

 relief in complete rest which he had been entreated to take for years 

 past, doing nothing more during the next three days than dictate a 

 few short letters to old personal friends. In one of them he said : 

 " All work of all kinds is forbidden me — a prohibition which, of 

 course, I shall not be able to obey. But the change which I have so 

 long dreaded is certainly come at last. I had trusted to be able to keep 

 in harness to the very last; but they tell me that a day's work such as 

 I have been accustomed to all my life would be simply suicide, and 

 that of course is not permitted." Late on the afternoon of the 19th, 

 the writer left him in the full belief that he was really better; but the 

 presaged change had indeed come ; for at 9 o'clock the next morning 

 he was summoned back to that bedside, only to find that the spirit 

 had already passed away. 



For his many and valuable services to chemical industry, Mr. 

 Weldon received the following distinctions : In France, the Great 

 Medal of La Societe d'Encouragement, and the Chevaliership of the 

 Legion of Honour. In this country, he was elected a Fellow of the 

 Royal Society (in 1882), Vice-President of the Chemical Society, Vice- 

 President of the Institute of Chemistry, and President of the Society 

 of Chemical Industry.
