First description and the first announcement of the invention of the Mine Safety Lamp, the so-called "Davy-Lamp" together with his further remarks on the functioning of this lamp. The papers are miliestones of applied chemistry.
"In 1815 he (Davy) invented the Davy lamp, in which an open flame is surrounded by a cylinder of metallic gauze. Oxygen can get through the gauze and feed the flame. The heat of the flame, however, is dissipated by the metal and explosive gases outside the lamp and not ignited. For the first time, miners were reasonably safe from explosion. In 1818 Davy was made a Baronet for his service to industry." (Asimow).
