At Johannesburg he gave the second half of his Address. Then on by
Bloemfontein, Kimberley, Bulawayo, to the Victoria Falls, where a bridge
had to be opened. Then to Portuguese Africa on September 16, 17, where
he made speeches in French and English. Finally he arrived at Suez on
October 4, and got home October 18.

It was generally agreed that his Presidentship was a conspicuous success.
The following appreciation is from the obituary notice in _The
Observatory_, January 1913, p. 58:

The Association visited a dozen towns, and at each halt its President
addressed an audience partly new, and partly composed of people who
had been travelling with him for many weeks. At each place this
latter section heard with admiration a treatment of his subject
wholly fresh and exactly adapted to the locality.

Such duties are always trying, and it should not be forgotten that tact
was necessary in a country which only two years before was still in the
throes of war.

In the autumn he received the honour of being made a K.C.B. The
distinction was doubly valued as being announced to him by his friend Mr.
Balfour, then Prime Minister.

From 1899 to 1900 he was President of the Royal Astronomical Society.
One of his last Presidential acts was the presentation of the Society's
Medal to his friend M. Poincare.

He had the unusual distinction of serving twice as President of the
Cambridge Philosophical Society, once in 1890-92 and again 1911-12.

In 1891 he gave the Bakerian Lecture {182a} of the Royal Society, his
subject being "Tidal Prediction." This annual praelection dates from
1775, and the list of lecturers is a distinguished roll of names.

In 1897 he lectured at the Lowell Institute at Boston, and this was the
origin of his book on _Tides_, published in the following year. Of this
Sir Joseph Larmor says {182b} that "it has taken rank with the
semi-popular writings of Helmholtz and Kelvin as a model of what is
possible in the exposition of a scientific subject." It has passed
through three English editions, and has been translated into many foreign
languages.
