CODICIL'LUS. Diminutive of CODEX. But in the plural, CODICILLI were a collection of small tablets employed for writing memorandums (Cic. Fam. ix. 26.), intended to be copied out fairly afterwards; to be despatched as letters to intimate friends (Cic. Fam. vi. 18.); for noting down the particulars of a will (Plin. Ep. ii. 16.); of a petition or memorial (Tac. Ann. iv. 39.), and other similar purposes.
