‎First apearance in French of Volta's paper dealing with meteorological phenomena, the causes of storms, hailstorms etc. Volta’s interest in meteorology began already in 1752 where he dealt with electricity in the atmosphere.‎

‎(Paris, Bachelier, 1838). 4to. No wrappers. In: ""Comptes rendus hebdomadaires des séances de l’Académie des sciences"", Vol. 7, No 11. Pp. (543-) 601. Morse's paper: pp. 593-95. Steinheil's paper: pp. 590-593. A faint dampstain in upper margin, otherwise clean and fine.‎

‎First printing of Morse's French announcement of his first successfull display of his invention at an 1838 exhibition in New York (January 6) where Morse transmitted 10 words per minute. He had retired his number-word dictionary, using instead the dot-dash code directly for letters. Although other changes would eventually be made, the Morse Code that would become standard throughout the world had been born. In the paper he also gives full credit to Carl August von Steinheil for his discoveries concerning the electrical telegraph.In the paper Steinheil describes his own telegraph and its predecessors. In reality, Steinheil's telegraph was the first recording telegraph, and it predating Morse.‎

‎First edition. In this importent paper Euler perfection Segner's hydraulic turbine, giving the theory of hydraulic turbines created in accordence with the principle of action and reaction.""In this work, Euler gives a complete hydraulic analysis, an early example of the theory of relative motion. He also shows that very high speeds are necessary for good efficiency. He argues that ""by means of fixed conducting tubes, adjust the incoming velocity of the water so that the speed of efflux relative to the rotor is zero"" in this way, the theorietical efficiency will be 100% at the desired speed of operation.""""(Truesdell).Enestroem: 179. ‎
