Another possible explanation is a lower iron content–and hence a less positive phase shift—in remyelinated lesions and black holes reducing the phase shift caused by demyelination.
There is a certain little instrument, the first of those in use with scholars, and the meanest, considering the materials of it, whether it be a joint of wheaten straw (the old Arcadian pipe) or just three inches of slender wire, or a stripped feather, or a corking pin.
