death, Mrs. Arnott granted an additional sum of ^4000 to be divided 

 among these Universities. Thus within the period of seven years Dr. 

 and Mrs. Arnott had contributed the sum of ten thousand pounds for 

 the promotion of scientific knowledge. 



Dr. Arnott was a man of genial disposition, and had a large circle of 

 friends. He took a delight in the society of these friends and in the 

 progress of scientific research, until the infirmities of age compelled him 

 in a great measure to withdraw from social intercourse. 



He died in the 86th year of his age, and up to the last year of his life his 

 mind was still actively occupied in devising and maturing new projects or 

 inventions. Among these may be mentioned a chair-bed for the pre- 

 vention of sea- sickness and a floating breakwater. It was the delight 

 of his life to devise means of ameliorating suffering and adding to human 

 comfort. 



Dr. Arnott died in the Eoman Catholic faith, and by his own desire 

 his body was buried in the Dean Cemetery, at Edinburgh, in the grave 

 in which the remains of his mother and other members of his family are 

 deposited. An obelisk with an appropriate inscription in commemoration 

 of himself and them has been erected over the grave.
