Reading edition
"Siculus Flaccus says that it was the practice of some agrimensores to place under termini ashes, or charcoal, or pieces of broken glass or pottery, or asses, or lime, or plaster (gypsum).... The writer of a later treatise, or rather compilation, attributed to Boëthius, speaking upon the same subject, enumerates as the objects to be so placed, ashes, or charcoals, or potsherds, or bones, or glass, or assæ of iron, or brass, or lime, or plaster, or a fictile vessel."—"The Romans of Britain," by H. C. Coote F.S.A.
