Association, and appointed as its delegate, G. H. Darwin.
By his former researches and by his high scientific character, he,
more than any other, was entitled to this position, which would
afford him an excellent opportunity of furthering, by his
recommendations, the study of theoretical geodesy. . .

We cannot relate in detail his valuable co-operation as a member of
the Council in the various transactions of the Association, for
instance, on the junction of the Russian and Indian triangulations
through Pamir, but we must gratefully remember his great service to
the Association when, at his invitation, the delegates met in 1909
for the 16th General Conference in London and Cambridge.

With the utmost care he prepared everything to render the Conference
as interesting and agreeable as possible, and he fully succeeded.
Through his courtesy the foreign delegates had the opportunity of
making the personal acquaintance of several members of the Geodetic
staff of England and its colonies, and of other scientific men, who
were invited to take part in the Conference; and when after four
meetings in London the delegates went to Cambridge to continue their
work, they enjoyed the most cordial hospitality from Sir George and
Lady Darwin, who, with her husband, procured them in Newnham Grange
happy leisure hours between their scientific labours.

At this conference Darwin delivered various reports, and at the
discussion on Hecker's determination of the variation of the vertical
by the attraction of the moon and sun, he gave an interesting account
of the researches on the same subject made by him and his brother
Horace more than 20 years ago, which unfortunately failed from the
bad conditions of the places of observation.

In 1912 Sir George, though already over-fatigued by the preparations
for the Mathematical Congress in Cambridge, and the exertions
entailed by it, nevertheless prepared the different reports on the
geodetic work in the British Empire, but, alas, his illness prevented
him from assisting at the conference at Hamburg, where they were
presented by other British delegates. The conference thanked him,
and sent him its best wishes, but at the end of the year the
Association had to deplore the loss of the man who in theoretical
geodesy as well as in other branches of mathematics a
