Abstract
This paper contains two results related to the question of when a measure on a metric space is determined by its value on certain subsets. The first is that two finite positive measures on a countable metric abelian group \(G\) which agree on all balls of some fixed non-zero radius agree on \(G\). The second relates to measures on a compact metric space that agree on all intersections of pairs of balls.
