Meanings of unnecessary particularity in anglès

Nat Grigsby tells us, with unnecessary particularity, that "essays and poetry were not taught in this school."

It may be objected that unnecessary particularity has been shown in the translation of various titles, names of Societies or newspapers, quotations, etc.

They furnish excuse, too, for what may appear to learned agriculturists an unnecessary particularity in what might seem the well-known facts relative to tile-drainage.
