in length is 0.000157 of an inch; and
with all other rays the results are the same--the difference varying
with a uniform increase from the violet to the red.

(*32) Place a platina crucible over a spirit lamp, and keep it a red
heat; pour in some sulphuric acid, which, though the most volatile of
bodies at a common temperature, will be found to become completely fixed
in a hot crucible, and not a drop evaporates--being surrounded by an
atmosphere of its own, it does not, in fact, touch the sides. A few
drops of water are now introduced, when the acid, immediately coming in
contact with the heated sides of the crucible, flies off in sulphurous
acid vapor, and so rapid is its progress, that the caloric of the water
passes off with it, which falls a lump of ice to the bottom; by taking
advantage of the moment before it is allowed to remelt, it may be turned
out a lump of ice from a red-hot vessel.

(*33) The Daguerreotype.

(*34) Although light travels 167,000 miles in a second, the distance
of 61 Cygni (the only star whose distance is ascertained) is so
inconceivably great, that its rays would require more than ten years to
reach the earth. For stars beyond this, 20--or even 1000 years--would
be a moderate estimate. Thus, if they had been annihilated 20, or 1000
years ago, we might still see them to-day by the light which started
from their surfaces 20 or 1000 years in the past time. That many which
we see daily are really extinct, is not impossible--not even improbable.

Notes -- Domain of Arnheim

(*1) An incident, similar in outline to the one here imagined, occurred,
not very long ago, in England. The name of the fortunate heir was
Thelluson. I first saw an account of this matter in the "Tour" of Prince
Puckler Muskau, who makes the sum inherited _ninety millions of pounds_,
and justly observes that "in the contemplation of so vast a sum, and of
the services to which it might be applied, there is something even of
the sublime." To suit the views of this a
