17248 Treatise on the Motion of Vortex Rings, ivith 8 diagrams, 8vo. cl. (very scarce), 



175 Gd 1883 



• In this essay, in addition to the set subject: •a general investigation of the action on each other of two closed 

 vortices in a perfect incompressible fluid ', I have discussed some points which are intimately connected with it, and I 

 have endeavoured to api)ly some of the results to the vortex atom theory of matter.'— Pre/acc. It was awarded the 

 Adams Prize of Cambridge University. 



Written under the a^gis of the Helmholtz-Kelvin Vortex Theory, when the indestructible ether vortex, moving in an 

 absolutely frictionless medium, was supposed to be the last word in the question of the constitution of matter, it yet 

 bids fair to contribute towards its explanation even under the spell of the Electron Theory.
