BELOW ZERO
liquefied helium under reduced pressure the temperature
of —454° Fahrenheit was reached—only 6° from the
absolute zero. It might therefore be thought that this
interesting point was practically within reach, for an
interval of 6° does not seem a very serious obstacle. At
these low temperatures, however, an advance of even 1° is
a very great matter, and it must be confessed that there
is no immediate prospect of reaching the chilly goal.
