29. NE ... INSTRUAT: _docere_ is to impart knowledge, _instituere_
(literally 'to ground' or 'establish') is to form the intellect and
character by means of knowledge, _instruere_, to teach the pupil how he may
bring his acquirements to bear in practical life. -- OFFICI MUNUS:
'performance of duty'; cf. 35, 72; Fam. 6, 14. In scores of passages in
Cicero we find _officium et munus_, 'duty and function', as in 34. -- CN.
ET P. SCIPIONES: in Cic. the plural is always used where two men of the
same family are mentioned and their names connected by et. In other writers
the plural is regular, the singular exceptional, as in Sall. Iug. 42, 1

nouns the plural is regular; e.g. Cic. Phil. 2, 101 _arationes Campana et
Leontina_, though a little above we have _mense Aprili atque Maio_. [See

they were hemmed in and killed, after a crushing defeat. -- L. AEMILIUS:
the father of Macedonicus. He was consul in 219 and defeated the Illyrii;
but when consul again in 216 was defeated and killed at Cannae. See 75. For
_avi duo_ cf. 82. -- CONSENUERINT ... DEFECERINT: _coniunctio_, for which
see n. on 16. For the mood see A. 313, _a_; G. 608; H. 515, III. and n. 3.
-- ETSI: see n. on 2. -- SENECTUTE: MSS. and edd. have _senectutis_, but

P. 13. -- 30. CYRUS: the elder. -- APUD XENOPHONTEM: 'in Xenophon'; so in
