  This is an annotated translation from German of Untersuchung einer nach den
Euler'schen Vorschlagen (1754) gebauten Wasserturbine [Investigation of a water
turbine built according to Euler's proposals (1754)] that reports the tests
results of a modern (1944) prototype of the so-called Segner-Euler turbine,
which was strictly constructed according to Euler's prescription as laid down
in E222 -- Theorie plus complete des machines qui sont mises en mouvement par
la reaction de l'eau. (Memoires de l'academie des sciences de Berlin 1756, Vol.
10, pp. 227-295.), showing the feasibility of Euler's original proposal. A
reproduction of the original paper is attached at the end of the translation.
