I wrote a draft of my Paper on the figure of Saturn, and on
Mar. 15th, 1824, it was read at the Philosophical Society under the
title of 'On the figure assumed by a fluid homogeneous mass, whose
particles are acted on by their mutual attraction, and by small
extraneous forces,' and is printed in their Memoirs. I also wrote a
draft of my Paper on Achromatic Eye-pieces, and on May 17th, 1824, it
was read at the Philosophical Society under the title of 'On the
Principles and Construction of the Achromatic Eye-pieces of
Telescopes, and on the Achromatism of Microscopes,' including also the
effects of separating the lenses of the object-glass. It is printed in
their Memoirs.
"Amongst miscellaneous matters I find that on Mar. 22nd of this year I
began regularly making extracts from the books of the Book Society, a
practice which I continued to March 1826. On Mar. 27th, a very rainy
day, I walked to Bury to attend the funeral of my uncle William
Biddell, near Diss, and on Mar. 30th I walked back in rain and
snow. On Feb. 24th I dined with Cubitt in Cambridge. On May 21st I
gave a certificate to Rogers (the assistant in Crosse's school, and my
instructor in mathematics), which my mother amplified much, and which
I believe procured his election as master of Walsall School.
