<p><span class="smcap">Dear Charley</span>:—</p>
<p class="text">One evening this week we spent very pleasantly
at the Royal Polytechnic Institution for the advancement
of the arts and sciences in connection with
agriculture and manufactures. There is a large
theatre, where all sorts of lectures are delivered, at
various hours, upon philosophical and other subjects.
Lecturers occupy the theatre in succession, and take
up about half an hour. These are generally men
of respectable abilities. The building is full of
curiosities. We saw the model of the human ear,
about one hundred and forty times larger than the
natural organ. We saw a diving bell in the great
<span class='pagenum'><SPAN class="page" name="Page_123" id="Page_123" title="123"></SPAN></span>hall, which is frequently put into action, and visitors
are allowed to descend. That evening several made
the experiment. The interior of the bell is lighted
by thick plate glass. A very large number of models
are to be seen, and there is much to interest the
spectator. We heard a fine lecture respecting the
experiment of Foucault, by which the diurnal rotation
of the earth is said to be rendered visible to the eye.
Foucault is a young Parisian, who, whilst engaged in
some investigations with a pendulum in his mother's
cellar, made this discovery, as he claims it to be.
We saw the experiment repeated here on the same
scale as it has recently been shown at the Pantheon
at Paris. A brass sphere, weighing about five pounds,
was suspended from the lofty ceiling by a piece of
music wire, and made to vibrate in one plane over a
table graduated into degrees. After a few vibrations,
the direction of the pendulum appeared to be
changed, as though the table had moved round on
its owns axis.</p>
<p class="text">We passed an hour at the Egyptian Hall to see
the opening of the American Panorama of the
Overland Route to California. It bids fair to make
a hit in London. Last Sunday, "great exhibition"
sermons were abundant in London. Exeter Hal,
the largest place in London, holding about five thousand
persons, is to be used for three months for the
performance of divine service, to accommodate the
<span class='pagenum'><SPAN class="page" name="Page_124" id="Page_124" title="124"></SPAN></span>strangers who crowd the city. We all went, Sunday
evening, and heard the Rev. Thomas Binney, who
has quite a reputation. The hall was as full as it
could be, but we did not think the discourse as good
as it might be. It was rather declamatory.</p>
<p class="text">You no doubt remember how much our curiosity
was excited by hearing that Mr. Wyld was about to
place a model of the globe, of gigantic dimensions,
in the great exhibition. Well, he was unable to
obtain the space required, and so he has erected a
spacious building in Leicester Square. This building
is circular, with projecting entrances at the four
cardinal points of the compass. From the centre rises
a graceful dome. Here is placed the model of the
earth, fifty-six feet in diameter. The scale is about
ten miles to an inch. The arrangement before used
in the construction of globes is reversed in this case,
and the continents, islands, and seas are seen on the
<i>inner</i> surface. This seems like turning the world,
not upside down, but inside out. The mountains
and land are elevated to a scale. The spectators
travel round the globe on winding staircases, at the
distance of a few feet from the surface. I went the
other morning to the model, but was far less interested
than I expected. The rest of the party were
not present, and are willing to take my report. I
heard that Mr. Wyld has spent twelve thousand
pounds upon his undertaking.</p>
<p class="text"><span class='pagenum'><SPAN class="page" name="Page_125" id="Page_125" title="125"></SPAN></span>We selected a fine afternoon to visit the Zoölogical
Gardens in the Regent's Park, and, of course,
had a treat. I did not think much of the gardens
as far as the horticulture was concerned; but the
collection of animals was far beyond any thing I
had before witnessed. There are more than sixteen
hundred specimens. The animals are finely housed,
and their habits consulted in the arrangements of
their homes. We had the pleasure to see the young
elephant, only six months old, which had just been
received. It was about the size of a donkey. A
hippopotamus had recently been added to the collection,
and we were sadly vexed not to see it. It
was shut up at six o'clock, just as we reached its
house. George had his luck, and obtained a glimpse
of the retiring quadruped. We have been greatly
amused with the sight of hundreds of boys about
town, dressed in blue gowns, or long coats with
belts, short knee breeches, yellow stockings, and
shoes with tackles, but wear no caps or hats. In
all weathers they are bareheaded. I find that they
are the boys belonging to Christ's Hospital, a school
founded by Edward VI., in 1553, and generally
known in London as the Blue Coat School. The
scholars generally range from one thousand to twelve
hundred. The education, is said to be of the best
character, and many of the boys belong to families
of high respectability, and it is quite a matter of
<span class='pagenum'><SPAN class="page" name="Page_126" id="Page_126" title="126"></SPAN></span>desire to obtain scholarship here. They look very
funny in their old-fashioned rig. Each boy wears
bands like a clergyman. The school is in Newgate
Street, and is a fine modern edifice in the Tudor
style. The front is flanked by towers, and has
eight noble windows, which are separated by buttresses.
Over one of the galleries of the hall is a
fine picture, by Holbein, of Edward VI. granting
the charter to the Hospital, as it was then called.
Some of the best scholars of England were educated
here; and we remembered particularly Coleridge and
our special favorite, Charles Lamb.</p>
<p class="text">To-morrow we are to have a treat of the highest
kind. We are to spend the day at Windsor. I
feel pretty well acquainted with its history and associations,
but I shall spend the evening with George
in brushing up my information. There is nothing
more unpleasant than to find yourself in the presence
of things and places of which you painfully
feel an entire ignorance. If ever we meet again,
how much we shall have to chat over on our favorite topics!</p>
<p class="center">Yours always,</p>
