This
booklet
contains
a
concise,
elementary
exposition
of
the
thermo-
dynamics
of
gases
and
vapors
as
well
as
its
application in
the
theory
of the
steam engine
and
refrigerating
engines. Even
though
the booklet
displays
some
inaccuracy
with respect
to
the fundamental definitions
and expositions
(cf.,
e.g.,
the definition of
entropy,
p.
50),
it will
probably
stand in
good
stead [1]
to
many an
engineering
student
facing
his
exam
with
fragmentary
college
notebooks.

"Heat

Displacement

System"

The
author
examines
the foundations of
the
thermodynamic theory
of
capillarity
and
finds
in them
a
not
exactly
correct assumption; nothing
is
said about the order of
magnitude
of the
inaccuracies
that arise
from
this
[1]
assumption.
