‎Ueber den Zusammenhang der Oberflächenspannung der Flüssigkeiten mit ihrem Molecularvolumen. - [DISCOVERING THE ""LAW OF CAPILLARITY"" - ""LAW OF SURFACE TENSION""]‎

‎First appearance of this important paper in which Eötvös set forth his ""Law of Capillarity"" and thereby eliminating the errors that had twarted his predecessors such as Young, Laplace, Poisson and Gauss. The principle thus established, also called ""The weak equivalence Principle"", served as a BASIS FOR EINSTEIN'S THEORY OF RELATIVITY(Capillarity: the property or exertion of capillary attraction of repulsion, a force that is the resultant of adhesion, cohesion, and surface tension in liquids which are in contact with solids, causing the liquid surface to rise or be depressed...)""The beginnings of Eötvös’ scientific career are connected with liquids. He worked out a new way to determine surface tension, which subsequently became known as the reflection method. This method made it possible to determine precisely the surface tension of various liquids. During his experiments, Eötvós found a linear relationship between the molar surface energy of liquidsand their temperature. The proportionality factor is constant for all compound liquids independently of their composition. The molar surface energy is equal to the work needed to move one molecule from the inside of the liquid to its surface. Based on this finding, Eötvös was able to state the following relationship: with increasing temperature, the surface tension of a liquid decreases until, at the critical temperature, it becomes zero. Later this rule was named the Eótvös law and the proportionality constant the Eötvós constant. In case of liquids this constant is as fundamental as the universal gas constant in case of gases.""‎

‎The Variation of Molecular Surface-Energy with Temperature. Received March 14, - Read March 23, 1893.‎

‎(London, Harrison and Sons, 1894). 4to. No wrappers as extracted from ""Philosophical Transactions"", 1893, Vol. 184. Pp. 647-673 a. 2 plates.‎

‎First appearance of an importent paper in the history of physical chemistry in which the authors for the first time shows experimentally that ""the molecular surface energy decreases linearly with the temperature, and that the temperature coefficient of molecular surface energy is a colligative property. Determination of the temperature coefficient of molecular surface energy, therefore, were largely employed for the purpose of calculating the molecular weights, and therefrom the molecular complexity, of substances in the liquid state.""(Findley ""A Hundred years of Chemistry"", p. 79).‎

‎Über algebraische Gebilde mit Eindeutigen Transformationen in sich. - [HURWITZ SURFACE]‎

‎Leipzig, B. G. Teubner, 1893. 8vo. Bound with the original wrappers in contemporary half calf. In ""Mathematische Annalen"", Volume 41., 1893. Entire volume offered. Library label to upper part of spine. Extremities with wear, internally very fine and clean. Pp. 403-442. [Entire volume: IV, 604 pp.].‎

‎First printing of Hurwitz's paper on Riemann surface theory and hyperbolic geometry, today known as a Hurwitz surface" essentially a compact Riemann surface with precisely 84(g - 1) automorphisms, where g is the genus of the surface. This number is maximal by virtue of Hurwitz's theorem on automorphisms.The present volume contain several other papers by influential contemporary mathematicians. ‎
