of mind, Hartley's _Observations on Man_. This book, though it did
not, like the _Traité de Législation_, give a new colour to my
existence, made a very similar impression on me in regard to its
immediate subject. Hartley's explanation, incomplete as in many points
it is, of the more complex mental phenomena by the law of association,
commended itself to me at once as a real analysis, and made me feel by
contrast the insufficiency of the merely verbal generalizations of
Condillac, and even of the instructive gropings and feelings about for
psychological explanations, of Locke. It was at this very time that my
father commenced writing his _Analysis_ of the Mind, which carried
Hartley's mode of explaining the mental phenomena to so much greater
length and depth. He could only command the concentration of thought
necessary for this work, during the complete leisure of his holiday
for a month or six weeks annually: and he commenced it in the summer
of 1822, in the first holiday he passed at Dorking; in which
neighbourhood, from that time to the end of his life, with the
exception of two years, he lived, as far as his official duties
permitted, for six months of every year. He worked at the _Analysis_
during several successive vacations, up to the year 1829, when it was
published, and allowed me to read the manuscript, portion by portion,
as it advanced. The other principal English writers on mental
philosophy I read as I felt inclined, particularly Berkeley, Hume's
_Essays_, Reid, Dugald Stewart and Brown on Cause and Effect. Brown's
_Lectures_ I did not read until two or three years later, nor at that
time had my father himself read them.

Among the works read in the course of this year, which contributed
materially to my development, I owe it to mention a book (written on
the foundation of some of Bentham's manuscripts and published under
the pseudonyme of Philip Beauchamp) entitled _Analysis of the Influence
