are explained as anacolutha by Madv. in a most important and exhaustive excursus to his D.F. (p. 785, ed. 2), and are connected with other instances of broken sequence.  There is no need therefore to read sive here, as did Turn.  Lamb.  Dav. and others. Quam nos ... probamus:  cf.  Introd. p. 62. Erit explicanda:  for the separation of these words by other words interposed, which is characteristic of Cic., see 11, 17.  I am surprised that Halm and Baiter both follow Ernesti in his hypercritical objection to the phrase explicare Academiam, and read erunt against the MSS., making illa plural.  If erunt is read, erit must be supplied from it to go with disserendum, which is harsh. Quam argute, quam obscure:  at first sight an oxymoron, but argute need not only imply clearness, it means merely “acutely”. Quantum possum:  some MSS. have quantam, which is scarcely Latin, since in Cic. an accusative only follows nequeo, volo, malo, possum, and such verbs when an infinitive can be readily supplied to govern it.  For velle see a good instance in D.F. III. 68, where consult Madv. Constantiam:  the notions of firmness, consistency, and clearness of mind are bound up in this word, cf.  II. 53. Apud Platonem:  Timaeus, 47 B, often quoted or imitated by Cic., cf. De Leg. I. 58, Laelius 20, 47, T.D. I. 64.

Sec.8. Id est ... jubeo:  these words have been naturally supposed a gloss.  But Cicero is nothing if not tautological; he is fond of placing slight variations in phrase side by side.  See some remarkable instances of slightly varied phrases connected by id est in D.F. I. 72, II. 6, 90.  I therefore hold Halm and Baiter to be wrong in bracketing the words. Ea a:  Lamb., objecting to the sound (which is indeed not like Cic.), would read e for a, which Halm would also prefer. De, ab, and ex follow haurire indifferently in Cic. Rivulos consectentur:  so Wordsworth, “to hunt the waterfalls”.  The metaphor involved in fontibus—­rivulos is often applied by Cic. to philosophy, see esp. a sarcastic passage about Epicurus in N.D. I. 120. Nihil enim magno opere:  magno opere should be written in two words, not as magnopere, cf. the phrases maximo opere, nimio opere, the same holds good of tanto opere, quanto opere. L.  Aelii:  MSS. Laelii.  The person meant is L. Aelius Stilo or Praeconinus, the master of Varro, and the earliest systematic grammarian of Rome.  See Quintil. Inst.  Or. X. 1, 99, Gellius X. 21, Sueton. Gramm. 3. Occasum:  an unusual metaphor. Menippum:  a Cynic satirist, see Dict.  Biogr. Considerable fragments of Varro’s Menippean Satires remain, and have often been edited—­most recently
