The Vortex Ring Theory of Gases. 



Thus Boyle and Gay-Lussac's laws follow from the vortex atom 

 theory. 



At present the quantity p is quite undetermined. It could be 

 determined by comparing the coefficients of viscosity and the conduc- 

 tivity for heat of the gas, since these depend on the mean values of 

 different powers of p, and the ratio of such quantities evidently 

 depends on p. In this paper I shall not consider the theory of the 

 conduction of heat. If it were the same on the vortex atom theory 

 of gases as on the ordinary theory, then the distribution of velocities 

 would follow Maxwell's law, as the values of the ratio of the coeffi- 

 cient of viscosity to the conductivity deduced from this law agree 

 fairly well with experiment. For this to be the case —

and the number of molecules which have the quantities a, and p 

 between a and a + ea, p and P + ^P would be proportional to —
