Rh of symmetrically disposed components (molecules) can distinguish between the real and apparent directions of the magnetic stream, in other words, how it can distinguish between an impressed transverse motion and a transverse component of the magnetic field. The analogy between the Eulerian fluid and the luminiferous ether is strong, but at present is not strong enough to bear any great weight.

In spite of difficulties, it appears probable to the author that in the near future some use may be made of existing electrical theory as an auxiliary means of investigating the aerodynamics of flight. Thus, in the general dynamics of the periptery, and in connection with the relations of the strength of the cyclic motion and the magnitude of the load reaction, it may be that mathematical solutions exist, ready to hand, in the analogous electrical theory, such as appropriately interpreted may some day be found to be of service.
