ion seemed to me preposterous.

During my last year at Cambridge, I read with care and profound interest
Humboldt's 'Personal Narrative.' This work, and Sir J. Herschel's
'Introduction to the Study of Natural Philosophy,' stirred up in me
a burning zeal to add even the most humble contribution to the noble
structure of Natural Science. No one or a dozen other books influenced
me nearly so much as these two. I copied out from Humboldt long passages
about Teneriffe, and read them aloud on one of the above-mentioned
excursions, to (I think) Henslow, Ramsay, and Dawes, for on a previous
occasion I had talked about the glories of Teneriffe, and some of the
party declared they would endeavour to go there; but I think that they
were only half in earnest. I was, however, quite in earnest, and got
an introduction to a merchant in London to enquire about ships; but
the scheme was, of course, knocked on the head by the voyage of the
"Beagle".

My summer vacations were given up to collecting beetles, to some
reading, and short tours. In the autumn my whole time was devoted to
shooting, chiefly at Woodhouse and Maer, and sometimes with young Eyton
of Eyton. Upon the whole the three years which I spent at Cambridge were
the most joyful in my happy life; for I was then in excellent health,
and almost always in high spirits.

As I had at first come up to Cambridge at Christmas, I was forced to
keep two terms after passing my final examination, at the commencement
of 1831; and Henslow then persuaded me to begin the study of geology.
Therefore on my return to Shropshire I examined sections, and coloured
a map of parts round Shrewsbury. Professor Sedgwick intended to visit
North Wales in the beginning of August to pursue his famous geological
investigations amongst the older rocks, and Henslow asked him to allow
me to accompany him. (In connection with this tour my father used
to tell a story about Sedgwick: they had started from their inn one
morning, and had walked a mile or two, when Sedgwick suddenly stopped,
and vowed that he would return, being certain "that damned scoundrel"
(the waiter) had not given the chambermaid the sixpence intrusted to
him for the purpose. He was ultimately persuaded to give up the project,
seeing that there was no reason for suspecting the waiter of especial
perfidy.--F.D.) Accordingly he came and slept at my father's house.

A short conversation with him during this evening produced a strong
impression
