and I went on to Cambridge on the 23rd of
June.

"I had arranged to take a party of pupils to Keswick, and to take my
brother there. Mr Clarkson had provided me with introductions to Mr
Southey and Mr Wordsworth. On Wednesday, June 29th, 1825, we started,
and went by Leicester, Sheffield, Leeds, and Kendal, to Keswick,
calling at Edensor on the way. My pupils were Cleasby, Marshman,
Clinton, Wigram, Tottenham, and M. Smith. At Keswick I passed three
months very happily. I saw Mr Southey's family frequently, and Mr
Wordsworth's occasionally. By continual excursions in the
neighbourhood, and by a few excursions to places as distant as
Bowness, Calder Bridge, &c. (always climbing the intermediate
mountains), I became well acquainted with almost the whole of that
beautiful country, excepting some of the S. W. dales. A geological
hammer and a mountain barometer were very interesting companions. I
had plenty of work with my pupils: I worked a little Lunar Theory, a
little of Laplace's Equations, something of the Figure of the Earth,
and I wrote out very carefully my Trigonometry for the Encyclopaedia
Metropolitana. I read a little of Machiavelli, and various books
which I borrowed of Mr Southey. On Friday, Sept. 30th, my brother and
I left for Kendal, and after a stay of a few days at Edensor, arrived
at Cambridge on Oct. 11th.

"On Oct. 21st my Lectures to the Junior Sophs began, 39 names, lasting
to Dec. 13th. Those to the Senior Sophs, 16 names, Oct 29th to
Dec. 10th. I also examined Questionists as last year. I have notes
about a Paper on the connection of impact and pressure, read at the
Philosophical Society on Nov. 14th, but not printed, dipping-needle
problems, curve described round three centres of force, barometer
observations, theory of the Figure of the Earth with variable density,
and effect on the Moon, correction to the Madras pendulum, wedge with
friction, spots seen in my eyes, density of rays near a caustic. In
this term I accomplished the preparation of a volume of Mathematical
Tracts on subjects which, either from their absolute deficiency in the
University or from the unreadable form in which they had been
presented, appeared to be wanted. The subjects of my Tracts were,
Lunar Theory (begun Oct. 26th, finished Nov. 1st), Figure of the Earth
(1st part finished Nov. 18th), Precession and Nutation (my old MS. put
in order), and the Calculus of Variations. I applied, as is frequently
done, to the Syndicate
