AUST, a chapelry in that part of the parish of HENBURY which is in the upper division of the hundred of HENBURY, county of GLOUCESTER, 4 miles (W.S.W.) from Thornbury, containing 192 inhabitants. This village, surrounded by salt marshes, is situated on the banks of the Severn, over which was formerly a ferry, now abandoned, in consequence of the establishment of a more convenient communication at New Passage, a mile and a half lower down the river. That rare mineral, sulphate of strontian, and carbonate of strontian, has been found in the fissures of the rocks bordering on the Severn.
