A new series of translations has started, concerned with Euler's contribution to the theory of fluids; at present  E258 has been translated, as well as the first part of a more extensive investigation by Euler, in E396, describing the mathematical principles on which the motion of ideal fluids may be described.  

              Euler: Fluids : Several papers and short books on fluids are presented here, at

               present we have E258 and E396 part 1.
