present paper. These are not marked with a dagger (†)
Essex is, generally speaking, a well-defined district, and the
county has been divided by Professor Boulger2 into three provinces,
and these again into seven sub-provinces, according to the river-
valleys. This seems, however, to be going into too great detail

Brook) as C, or North Essex. Of these, Brook, or Saffron
