Note 265 — TALE OF KAMAR AL-ZAMAN,
Richard Francis Burton translation
Arab. "Kirát" from κεράτιον, i.e. bean, the seed of the Abrus precatorius, in weight = two to three (English) grains; and in length = one finger-breadth here; 24 being the total. The Moslem system is evidently borrowed from the Roman "as" and "uncia."
