Parametric Solution Of Certain Nonlinear Differential Equations In   Cosmology II
  This paper continues earlier work where an explicit parametrized solution of a particular nonlinear ordinary differential equation was obtained in terms of the Weierstrass elliptic phi-function, sigma function and zeta function -- work which therefore generalized that of G. Lemaitre. Further study of this solution and applications to cosmology are presented.
