ain, throwing aside all that he had
already done, and following up his new course of investigations at
Berlin, Dresden, the Hague, and Brussels during several succeeding years.
I do not know that I can give a better idea of his mode of life during
this busy period, his occupations, his state of mind, his objects of
interest outside of his special work, than by making the following
extracts from a long letter to myself, dated Brussels, 20th November,
1853.

After some personal matters he continued:--

"I don't really know what to say to you. I am in a town which, for
aught I know, may be very gay. I don't know a living soul in it.
We have not a single acquaintance in the place, and we glory in the
fact. There is something rather sublime in thus floating on a
single spar in the wide sea of a populous, busy, fuming, fussy world
like this. At any rate it is consonant to both our tastes. You may

friends out of the incidents of so isolated an existence. Our daily
career is very regular and monotonous. Our life is as stagnant as a
Dutch canal. Not that I complain of it,--on the contrary, the canal

steep promontory, the old part at the bottom, very dingy and mouldy,

more exquisite in its way than the grande place in the very heart of
the city, surrounded with those toppling, zigzag, ten-storied
buildings bedizened all over with ornaments and emblems so peculiar
to the Netherlands, with the brocaded Hotel de Ville on one side,
with its impossible spire rising some three hundred and seventy feet
into the air and embroidered to the top with the delicacy of needle-
work, sugarwork, spider-work, or what you will. I haunt this place
because it is my scene, my theatre. Here were enacted so many deep
tragedies, so many stately dramas, and even so many farces, which
