ON GRAVITATION IN GASEOUS NEBULAE. 

 Francis E. Nipher. 



In No. 3 of Vol. IX of these Transactions, appears a paper 

 by C. M. Woodward, on the distribution of pressures and 

 densities in a gaseous mass of constant temperature T^, which 

 is assumed to have a spherical form. At the surface of any 

 sphere of radius B^, whose center is at the center of mass, he 

 finds the density and pressure to be 



n2'Ti2 



The mass within the surface of radius R^ Woodward found 

 to be 



J/, = ^^yo. (3) 



The weight of a gramme at this surface is therefore 



In these equations k is the gravitation constant, and C is 

 the constant of the gas. 



The values of these quantities at any sphere whose radius 

 is II are also 





3 = .^^J^. (5)
