Abstract: Let $ \mathcal {H}^h$ be the $ h$-dimensional Hausdorff measure on $ \mathbb{R}^d$. Besicovitch showed that if a set $ E$ is null for $ \mathcal {H}^h$, then it is null for $ \mathcal {H}^g$, for some dimension $ g$ smaller than $ h$. We prove that this is not true for packing measures. Moreover, we consider the corresponding questions for sets of non-$ \sigma $-finite packing measure and for pre-packing measure instead of packing measure.
