1820 (about). _Chemical Lectures._ Designed and published by T.
Rowlandson, 1 James Street, Adelphi.--Sir Humphrey Davy is exhibiting
experiments at the Royal Institution before a highly respectable
audience of visitors and members of both sexes. An antiquated fogey,
who has evidently no opinion of the brilliant young lecturer, is
snarling at the demonstrations. A treatise of the period, _Accum's
Lectures_, is shown in his coat-pocket.
