xviii PERCY SLADEN TRUST EXPEDITION. 
delicate physique, and shortly after his marriage he became subject to recurrent attacks 
of influenza. These undermined his constitution, rendering him incapable of concen- 
trated attention to scientific pursuits, and less able to cope with the worries connected 
with the landed property near Exeter, with which, owing to the advanced years of his 
uncle Mr. Dawson, he now became closely associated. It was, in fact, the frequency of 
his visits to Exeter in connection with the management of this estate, coupled with his 
own failing health, which compelled him in 1895, to the great regret of his colleagues, 
to resign the Zoological Secretaryship of the Linnean Society, a post he had held for 
just ten years. 
After Mr. Dawson’s death in 1898, Sladen, now in possession of an ample fortune, 
made another effort to settle down to hard work, and the next two years saw a constant 
struggle between a brilliant mind eager for increased knowledge, and a body all too 
frail for the innumerable tasks which lay before it. Ill-health continuing, the Sladens 
arranged early in 1900 to make a lengthened tour in Italy, hoping that the more genial 
climate, with rest from work and worry, might completely restore his strength. Fora 
time this seemed a success, and Sladen, full of renewed energy and hope, started for 
home early in June; but a few days’ sight-seeing in Florence, during the great heat 
prevalent there at that season, proved too much for a heart already enfeebled by 
influenza; and while walking back to his hotel on the morning of June 11th, he 
complained of sudden illness, and died a few hours later, his last words and thoughts 
being for the wife whom he had loved so well, and cherished so tenderly, during the 
short term of their married life. 
Sladen’s unusually complete collection of Starfishes, including several type specimens, 
as well as a number of Crinoids which had belonged to his friend P. H. Carpenter, are 
now in the Royal Albert Museum at Exeter, to which they were presented by his widow 
a few years after his death.
