280 Ohituary Notice. 



lenger' Expedition, it was remarked that his long spell of 

 travel had not brought increased physical vigour ; but it 

 was not until 1879 that his condition gave his friends 

 serious cause for uneasiness. In June of that year he 

 was prostrated by an attack of paralysis, and unable to 

 conduct his class of Natural History in the University of 

 Edinburgh, and the important undertaking in which he 

 was engaged, of directing the working out of the ' Chal- 

 lenger' researches, with the view of furnishing to the 

 world a complete record of the results, had to be laid 

 aside, only to be intermittently touched again before the 

 time came when he had to resign it entirely into other 

 hands. In October last he resigned his chair in the 

 University, and arrangements had just been completed by 

 the Senatus in respect to his retiring allowance. Some 

 four months ago he had a second paralytic attack, and 

 since then his health has been feeble. He died on 

 Friday morning, 10th March 1882, at three o'clock. 



" The departments of zoology to which he devoted most 

 attention were those which included the corals, crinoids, 

 and sponges, and upon these his opinion was regarded as 

 of great weight. In the University he was held in 

 esteem by his colleagues of the Senatus, and among the 

 students he was exceedingly popular. In private life be 

 was regarded by his friends as possessed of a kindly and 

 hospitable disposition. 



" Sir Wyville Thomson married a sister of the late Mr 

 Adam Dawson of Bonnytoun, Linlithgowshire, for some 

 years Provost of Linlithgow, whose father also occupied 

 the same honourable position for the greater part of his 

 life. He is survived by Lady Thomson and one son, an 

 M.A. of the University of Edinburgh, who is at present 

 engaged in his study of law."
