5. Gibbs, J. W., “The Scientific Papers of J. Willard Gibbs.” Longmans, Green, New York, 1906. Volume I contains the extensive paper, “On the Equilibrium of Heterogeneous Substances” first published in the Transactions of the Connecticut Academy III, pp. 108–248, 343–524. These were published in 1875, 1876, and 1878. Gibbs laid out the fundamentals of chemical thermodynamics, which have had such wide application. For comments on the role of Gibbsian thermodynamics in biology, see Morowitz, H. J., A biologist's view of Gibbs' contributions, J. Wash. Acad. Sci. 64, 209, 1974.
