Laboratories at Shrewsbury School, October 20, 1911.

{141a} In the _Life and Letters of Charles Darwin_, Vol. I., are given
my father's autobiographical recollections. He wrote (pp. 31-32):
"Nothing could have been worse for the development of my mind than Dr.
Butler's school, as it was strictly classical, nothing else being taught,
except a little ancient geography and history." This seems to be an
exaggeration, as the following list shows. It is taken from Samuel
Butler's _Life and Letters of Dr. Samuel Butler_, 1896, Vol I., p. 196.
The "weekly course of instruction for the fifth and sixth forms, under
Dr. Butler," is given, and the items which are not classical are as
follows:--

_Monday_.--English History follows Grecian and Roman history. The rest
of a very full day is classical.

_Tuesday_.--Half-holiday. All classical except that the Masters of
accomplishments attend in the afternoon.

_Wednesday_.--All classical.

_Thursday_.--Half-holiday. All classical except a "Lecture in algebra"
for the sixth and upper fifth forms.

_Friday_.--All classical.

_Saturday_.--All classical except "Lecture in Euclid to sixth and upper
fifth."
