First appearance in German of Volta's importent paper in which he describes the electrical forces that acts between the metal-plates in the Voltaic Pile. The German publication was printed in the same year as the Italian original ""Sull' identita del Fluido Elettrico col Fluide Galvanico"", 1802.""A long memoir by Volta in two parts...reports that by measuring the electrometer deflections with different pairs of metals he found that the forces which drive the electric fluid...from the first metal to the second are: silver/copper 1, copper/iron 2, iron/thin 3, lead/tin 1, lead/zinc 5. Then the force for silver/zinc in immidiate contact is 12 (1+2+3+1+5), copper/tin 5 (= 3+2), iron/zinc 9 (5+1+3), etc. Thus 'the force or impulsion with which two metals act on the electric fluid is equal to the sum of the forces of the series of metals which stands between them, and...the electric force is the same as that which arises when the two extreme metals have no effect on the force of the latter'. This is the first statement of what Maxwell called 'Volta'slaw of contact electricity'...""(Partington IV, p.15.).

Three first editions by Euler. Euler's goal in the first paper is to show that certain phenomena that resulted from the eclipse of July 25, 1748 are evidence that the moon has an atmosphere that is almost 200 times less dense than that of the earth. (The phenomena Euler observed are optical effects of light passing close to a sharp edge, and not the refraction of a lunar atmosphere).The other papers on the physics of rigid bodies are groundbreaking as Euler here set forth what is known as ""Euler's dynamical equations of the motion of the mass-center of any solid"", and thus STATING FOR THE FIRST TIME THE LAW OF DRY FRICTION, mathematically. Euler explains his experiments with the inclined plane and discovers the DIFFERENCE BETWEEN KINETIC AND STATIC FRICTION.""Leonhard Euler occupied himself with the mathematical point of view of friction as well as the experimental. He introduced the differentiation between static frictional forces and kinetic frictional forces, and solved the problem of rope friction, probably the first contact problem to be analytically solved in history. (1750, the papers offered). He was the first to lay the foundations of the mathematically way of dealing with the law of dry friction and in this way promoted further development. We have to thank for the symbol as the coefficient of friction. Euler worked with the idea that friction originates from the interlocation, between small triangular irregularities.This understanding survived, in different variations,for a hundred years and is also used today as the ""Tomlinson Model"" in connection with friction on atomic scale.""(L. Popov ""History of the Contact Mechanics and the Physics of Function"", p.3).Eneström: E142, E143, E144.

First printing of this early rapport on the Voltaic Pile in which Biot quantizises Volta's Contact Theory.In the first part of the rapport Biot asserted the priority of Coulomb's notions over the entire science of electricity, while in the second part he introduces a mathematical model of the battery that established no link with Coulomb's Law.Wheeler Gift: No. 668.
