: Chemistry in Daily Life '
—I, Air and the Elements.' S.B. from Plymouth
CHEMISTRY is otio of the subjects that nearly all schoolboys enjoy, and it is one of the grudges that the older generation have against their own schooldays that it was not then included in a normal general education. In this series of talks Dr. Glcsstone (who is Lecturer in Chemistry at the University College of the South-West, Exeter) will introduce his listeners to the most interesting aspect of chemistry— the science of actual fact. This evening he will review different theoriesof air and of the elements, real and supposed, as held by scientists from the time of Aristotle to the present day, and he will talk about the mixture of gas's, familiar and obscure, that goes to make the air we breathe.
