The paper, as a continuation of the paper (Hanzel I., Carnap and Newton: Two approaches to the method of theory construction (Part I), ORGANON F, 2, 2009), provides a methodological generalization of Newton's method of theory construction as applied in Book I and Book III of his 'Principia'. It reconstructs also the method of measures applied in those books. Finally, it shows that Book I and Book III of the Principia can be viewed as a hierarchically organized sequence of gradually shifting constructions, and thus that the term 'harmonic law' inside these books changes its meaning.
