"I kept up classical subjects. I have a set of notes on the [Greek:
Ploutos] and [Greek: Nephelai] of Aristophanes, finished on Mar. 15th,
1823, and I began my daily writing of Latin as usual on Feb. 8th. In
mathematics I worked very hard at Lunar and Planetary Theories. I have
two MS. books of Lunar Theory to the 5th order of small quantities,
which however answered no purpose except that of making me perfectly
familiar with that subject. I worked well, upon my quires, the figure
of Saturn supposed homogeneous as affected by the attraction of his
ring, and the figure of the Earth as heterogeneous, and the Calculus
of Variations. I think it was now that I wrote a MS. on constrained
motion.

"On Mar. 17th, 1823, I was elected Fellow of the Cambridge
Philosophical Society. On May 9th a cast of my head was taken for Dr
Elliotson, an active phrenologist, by Deville, a tradesman in the
Strand.

"I had long thought that I should like to visit Scotland, and on my
once saying so to my mother, she (who had a most kindly recollection
of Alnwick) said in a few words that she thought I could not do
better. I had therefore for some time past fully determined that as
soon as I had sufficient spare time and money enough I would go to
Scotland. The interval between the end of Easter Term and the usual
beginning with pupils in the Long Vacation offered sufficient time,
and I had now earned a little money, and I therefore determined to go,
and invited my sister to accompany me. I had no private
introductions, except one from James Parker to Mr Reach, a writer of
Inverness: some which Drinkwater sent being too late. On May 20th we
went by coach to Stamford; thence by Pontefract and Oulton to York,
where I saw the Cathedral, which _then_ disappointed me, but I suppose
that we were tired with the night journey. Then by Newcastle to
Alnwick, where we stopped for the day to see my birthplace. On May
24th to Edinburgh. On this journey I remember well the stone walls
between the fields, the place (in Yorkshire) where for the first time
in my life I saw rock, the Hambleton, Kyloe, Cheviot and Pentland
Hills, Arthur's Seat, but still more strikingly the revolving Inch
Keith Light. At Edinburgh I hired a horse and gig for our journey in
Scotland, and we drove by Queensferry to Kinross (where for the first
time in my life I saw clouds on the hills, viz. on the Lomond Hills),
and so to Perth. Thence by Dunkeld and Killicrankie to Blai
