First apperance of the paper in which Thomas Andrews announces his discovery of the ""CRITICAL POINT"", which states that for every gas there was a temperature above which pressure alone could not liquefy it.""This was a crucial discovery for it pointed the way toward the liquefaction of the permanent gases by demonstrating the necessity of dropping the temperature below the critical point before exerting pressure. This new view led within half a century to the work of Dewar and Kammerlingh-Onnes and the liquefaction of all known gases.""(Asimov).Magie: A Source Book in Physics, pp. 187-192. - Parkinson, Breakthroughs: 1869 C.
