A new and simple method of measur-
ing small variations of the length of
bar has lately been devised by means of a
wire giving a determinate number of
vibrations. When the bar expands the
wire becomes less tense and gives fewer
vibrations and there is simple relation
between the number of vibrations and
the length of the bar.
