XIV.—Further Experiments and Remarks on the Measurement of Heights by the Boiling Point of Water

James D. Forbes
1857 Transactions of the Royal Society of Edinburgh  
In 1843 I presented a paper to the Royal Society of Edinburgh, giving an account of experiments made on the boiling point of water in the Alps, under various barometric pressures. My object was twofold: first, to describe an apparatus which I considered more practically available than those previously in use; and, secondly, to give a simple, and, as I believed, new formula for computing heights from such observations.With reference to the second point, I became aware, some time after the
more » ... me after the publication of my paper, that Sir John Leslie had proposed to compute heights by the thermometer, assuming the change of the boiling point to beexactlyin proportion to the height ascended. While cheerfully conceding to Sir John Leslie priority on this point, I submit that he did not bring forward experiments to justify its practical adoption.
