In the 1830s, in ''[[Bridgewater Treatises|The Bridgewater Treatises]]'', the term ''convection'' is attested in a scientific sense. In treatise VIII by [[William Prout]], in the book on [[chemistry]], it says:<ref>{{Cite book |last=Prout |first=William. |url=http://archive.org/details/chemistrymeteoro00pro |title=Chemistry, meteorology and the function of digestion: considered with reference to natural theology |publisher=William Pickering |year=1834 |series=The Bridgewater Treatises: On the power, wisdom and goodness of God as manifested in the creation.

<blockquote>[...] This motion of heat takes place in three ways, which a common fire-place very well illustrates. If, for instance, we place a thermometer directly before a fire, it soon begins to rise, indicating an increase of temperature. In this case the heat has made its way through the space between the fire and the thermometer, by the process termed ''[[radiation]]''. If we place a second thermometer in contact with any part of the grate, and away from the direct influence of the fire, we shall find that this thermometer also denotes an increase of temperature; but here the heat must have travelled through the metal of the grate, by what is termed ''[[Thermal conduction|conduction]]''. Lastly, a third thermometer placed in the chimney, away from the direct influence of the fire, will also indicate a considerable increase of temperature; in this case a portion of the air, passing through and near the fire, has become heated, and has ''carried'' up the chimney the temperature acquired from the fire. There is at present no single term in our language employed to denote this third mode of the propagation of heat; but we venture to propose for that purpose, the term ''convection'', [in footnote: [Latin] ''Convectio'', a carrying or conveying] which not only expresses the leading fact, but also accords very well with the two other terms.

Later, in the same treatise VIII, in the book on [[meteorology]], the concept of convection is also applied to "the process by which heat is communicated through water".
