Offprint from Philosophical Transactions of the Royal Society of London, Vol. 118. Davy was famously fascinated by volcanoes, recreating one out of clay, gravel and potassium at his farewell lecture at the Royal Institution in 1812. His theory was that volcanic activity was caused by heat produced during the oxidisation of alkaline earths, an idea that he first promoted in 1808 and to which he still clung despite recent research having shown that air could not reach sufficient depths to cause widespread oxidisation.
