"Of the time in this term that I have started to think about the possibility of
observing the diminution of the gravity in a deep mine, and it communicated
with Whewell that was prepared for connecting in experiments. My first notion
it was to simply try the percentage of a clock, and the mine of first Ecton was
thought of. I made enquiries on the Ecton you dig through Smith of Mr (of
Edensor), and it visited the mine, but in the meantime Whewell had done

I was taken part in correspondence with Mr. H. Davy (the President of
the Real Society), Mr Herschel and the Dr Young (Secretary of the Board
of Longitude) on the loan of tools and pendulums. On
April. 23 I was practising pendulum-observations (from coincidence); and
around this duration it repeatedly practised transits with a small tool
lent by Mr Sheepshanks (with whom my knowledge has had to start anybody
time along first) what erect was under a curtain the Individuals'
Walks. On my quires I find the various schemes to graduate thermometers
for experiments of pendulum.
"I also find Note of examination of my brother William that had come
to the university last October; and a lot of correspondence with mine
mother and sister and Case of Mr, a lawyer, on an annoying business
with Mr Cropley, an old friend of G. Biddell, to whom my father had
