plete reports of the Expedition, and still attended meetings of the 
Commissioners of Supply for his native county. He even sat as 
magistrate sixteen days before his fatal illness. But from his first 
seizure he was unable to discharge the duties of his chair, and 
retired from them altogether in the October of 1881. Subsequently 
he had also to relinquish his position as “ Director of the 4 Chal- 
lenger’ Expedition Commission.” In the beginning of March 1882 
his critical condition was manifested by his making a personal 
application to be relieved from attending at the Fiars’ Court on the 
10th of that month, the very day on which his last seizure proved 
fatal. He died at the early age of fifty-two, having made many 
lasting contributions to science, secured large numbers of sincere 
admirers and friends, and received the applause and approval of 
scientific men everywhere for the wisdom, energy, skill, and 
courtesy which he had shown in the direction of the most extended 
and successful of scientific expeditions.

The Commissioners of Supply of the county of Linlithgow, with 
a committee of scientific and other friends in Edinburgh, have 
collected several hundred pounds for the purpose of erecting a 
lasting memorial to commemorate the distinguished services of the 
late Sir Charles Wyville Thomson, and it has been resolved to 
place a bust by Hutchison in the University of Edinburgh, and a 
memorial window in the beautiful collegiate church in his native 
place.
