William Dennison, whom he accompanied on his tours throughout 
the Presidency in 1861-62. He acted as medical attendant to 
His Excellency, and also to his successor. Sir Hope Grant, and 
their suites. In May 1863 he was placed on the retired India list. 
From that time he resided in Edinburgh, and took an earnest and 
active part in professional, scientific, philanthropic, and religious 
movements. He was elected a Fellow of this Society in 1863, and 
for some time was a Member of Council. In the same year he 
became a Member of the Scottish Meteorological Society, and a 
Member of its Council in 1865, Honorary Treasurer in 1872, and 
Honorary Treasurer to the Ben He vis Observatory in 1883, when 
the Observatory was established. He was most regular in attendance 
at Council, Committee, and General Meetings, and devoted a very 
large portion of his time not merely to the more special duties of 
Treasurer, but also in forwarding the extension of its membership, 
and in promoting whatever tended to increase the efficiency of the 
work of the Society. 
From the beginning of his career to the end, Dr Sanderson was 
an ardent learner. After settling in Edinburgh, he attended several 
of the medical classes of the University with the view of being 
brought more abreast with the different departments of his profes- 
sion ; and latterly, when Dr Whyte began his classes for young 
men on Sunday evenings, which are in no small degree academical 
in character, he, and his friend, Mr Donald Beith, whose obituary 
was read at last meeting, were among the most regular attenders of 
the class. 
His professional success in India was the result of the remarkable 
openness and teachableness of his mind in quest of information 
from all quarters, his firmness of character when required, but, 
above all, to the unfailing cheeriness of the man, which inspired 
hope and ultimate recovery to many a sick-bed. In these vari- 
ous capacities he was able to perform most effective service by his 
earnestness of purpose, his enthusiastic nature, and his singularly 
genial and kindly manner.
