The volume dilatometer, although inexpen sive and simple in construction and principle, is found to be a valuable research tool, no t only for obtaining dat a on volume coefficients of thermal expansion, but also for studying phase changes in solids and liquids. . The pr~p aration and operation of the volume dilatometer are described in detail. An Illustrative calculation is given using data obtained from volume-temperature measurem.ent s .on.a s~mple of butyl rubber from about -30 0 to + 90 0 C, using mercury as a confil1lng lIqUid III the dilatometer .
