  The notion of newtonianity is central to the study of the ordered
differential field of logarithmic-exponential transseries done by
Aschenbrenner, van den Dries, and van der Hoeven; see Chapter 14 of
arxiv:1509.02588. We remove the assumption of divisible value group from two of
their results concerning newtonianity, namely the newtonization construction
and the equivalence of newtonianity with asymptotic differential-algebraic
maximality. We deduce the uniqueness of immediate differentially algebraic
extensions that are asymptotically differential-algebraically maximal.
