“Pass the tube of an air thermometer or of an inverted mercury thermometer through a cork in the neck of a funnel. Cover the thermometer bulb to the depth of about half an inch with water. Upon the water, pour a little sulphuric ether and ignite it. The thermometer below will scarcely be affected, although the water above may be boiling. Stir the water and note the prompt movement of the thermometer index...” -Avery 1895
