Abstract
APART from the determination of the characteristics of the liquefied gases used to produce low temperatures, the original aim of low temperature research was to investigate the fundamental properties of matter in the absence of the disturbing effects produced by thermal agitation. Although this aim has been to a large extent achieved, its attainment has been complicated and research made more exciting by new phenomena which have appeared in this temperature region, and by previously known phenomena which have become relatively more important. Incidentally, the rapid advance of this branch of physics is illustrated by the fact that most physicists would now confine the term 'low temperature' to the region within a few degrees of the absolute zero.
