It is almost needless to add that his memory was
equally accurate and extensive in matters connected with science or
business.

His independence of character was no doubt due to and inseparable from
his great powers. The value of his scientific work greatly depended
upon his self-reliance and independence of thought. And in the heavy
work of remodelling the Observatory it was a very valuable
quality. This same self-reliance made him in his latter years apt to
draw conclusions too confidently and hastily on subjects which he had
taken up more as a pastime than as work. But whatever he touched he
dealt with ably and in the most fearless truthseeking manner, and left
original and vigorous opinions.

He had a remarkably well-balanced mind, and a simplicity of nature
that appeared invulnerable. No amount of hero-worship seemed to have

to a great deal of it. His mind was incessantly engaged on
investigations of Nature, and this seems to have been with him, as has
been the case with others, a preserving influence. This simplicity of
character he retained throughout his life. At the same time he was
sensible and shrewd in his money matters and attentive to his personal
interests. And his practical good sense in the general affairs of
life, combined with his calm and steady consideration of points
submitted to him, made his advice very valuable. This was especially

many occasions and placed the fullest confidence in his absolute sense
of justice as well as in his wise counsel. He was extremely liberal
in proportion to his means, and gave away money to a large extent to
all who had any claim upon him. But he was not in any sense reckless,
and kept a most cautious eye on his expenses. He was not indifferent
to the honours which he received in the scientific world, but he does
not appear to have sought them in any way, and he certainly did not
trouble himself about them.

His courtesy was unfailing: no amount of trouble could shake
it. Whether it was the Secretary of the Admiralty, or a servant girl
wanting her fortune told: whether a begging-letter for money, or
miscellaneous invitations: all had their answer in the most clear and
courteous language. But he would not grant personal interviews when he
could avoid it: they took up too much of his time. His head was so
clear that he never seem
