which are fixed in front of the galleries, at the east and west ends
of the building. I am afraid that it would tire you, were I to attempt
to tell you exactly what electricity is, and must therefore satisfy
your curiosity, for the present, by letting you know that it is caused
by the coming in contact of different substances possessing peculiar
properties, which cause them to vibrate, when they touch.

There is another very curious clock in the Exhibition, which will go
for a hundred years before requiring to be wound up again; and there
is one wheel in it which is said would take ten thousand years to go
round once.

Next there is a case of stuffed birds, which came from Scotland, and
which we cannot help admiring. There are in this case specimens of all
the various kinds of birds which are peculiar to Scotland, neatly and
carefully stuffed; and really they almost look as if they were alive.
Ah, ah! Mister Eagle, you are not so much to be feared now, I think,

mother-of-pearl buttons that can be imagined; there is every variety
of ornament on the buttons, which look exceedingly brilliant.

This immense block of granite, from Scotland, is not quite so pretty,
though it is, perhaps, more useful; it is twenty feet long, and is a
piece of the finest kind and colour that could be found. Another very
useful thing, also from Scotland, is a large lighthouse bell, managed
so as to ring very loud, to warn any ship that is going too near a
dangerous rock or shoal, near the lighthouse where the bell may be.
