Professor Gibbs’s scattered papers on scientific subjects have been collected and published in two imposing volumes. The first includes his papers on the equilibrium of heterogeneous substances and on thermodynamics; the second contains twenty-one papers, chief among which are those occupied with the author’s calculus called “vector analysis.”

“For profound thought and power of generalization and abstract formulation no American scientist has equaled Willard Gibbs.”
