§100. _Si iam_: "if, for example;" so _iam_ is often used in Lucretius. _Probo ... bono_: it would have seemed more natural to transpose these epithets. _Facilior ... ut probet_: the usual construction is with _ad_ and the gerund; cf. _De Div._ II. 107, _Brut_. 180. _Anaxagoras_: he made no ‛ομοιομερειαι of snow, but only of water, which, when pure and deep, is dark in colour. _Concreta_: so Manut. for MSS. _congregata_. In 121 the MSS. give _concreta_ without variation, as in _N.D._ II. 101, _De Div._ I. 130, _T.D._ I. 66, 71. §101. _Impeditum_: cf. 33, n. _Movebitur_: cf. _moveri_ in 24. _Non enim est_: Cic. in the vast majority of cases writes _est enim_, the two words falling under one accent like _sed enim, et enim_ (cf. Corss. _Ausspr._ II. 851); Beier on _De Off._ I. p. 157 (qu. by Halm) wishes therefore to read _est enim_, but the MSS. both of the _Lucullus_ and of Nonius agree in the other form, which Madv. allows to stand in _D.F._ I. 43, and many other places (see his note). Cf. fragm. 22 of the _Acad. Post_. _E robore_: so Nonius, but the MSS. of Cic. give here _ebore_. _Dolatus_: an evident imitation of Hom. _Od._ T 163 ου γαρ απο δριος εσσι παλαιφατου ουδ' απο πετρης. _Neque tamen habere_: i.e. _se putat_. For the sudden change from _oratio recta_ to _obliqua_ cf. 40 with n. _Percipiendi notam_: = χαρακτηρα της συγκταθεσεως in Sext. _P.H._ I. 191. For the use of the gerund cf. n. on 26, with Madv. _Gram._ 418, Munro on Lucr. I. 313; for _propriam_ 34. _Exsistere_. cf. 36. _Qui neget_: see 79. _Caput_: a legal term. _Conclusio loquitur_: cf. _historiae loquantur_ (5), _consuetudo loquitur_ (_D.F._ II. 48), _hominis institutio si loqueretur_ (_ib._ IV. 41), _vites si loqui possint_ (_ib._ V. 39), _patria loquitur_ (_In Cat._ I. 18, 27); the last use Cic. condemns himself in _Orat._ 85. _Inquit_: "quotha," indefinitely, as in 109, 115; cf. also _dicit_ in 79. §102. _Reprehensio est ... satis esse vobis_: Bait. follows Madv. in placing a comma after _est_, and a full stop at _probabilia_. _Tamen_ ought in that case to follow _dicimus_, and it is noteworthy that in his communication to Halm (printed on p. 854 of Bait., and Hahn's ed. of the philosophical works, 1861) Madv. omits the word _tamen_ altogether, nor does Bait. in adopting the suggestion notice the omission. _Ista diceret_: "stated the opinions you asked for." _Poetam_: this both Halm and Bait. treat as a gloss. §103. For this section cf. Lucullus' speech, passim, and Sext. _P.H._ I. 227 sq. _Academia ... quibus_: a number of exx. of this change from sing. to plural are given by Madv. on _D.F._ V. 16. _Nullum_: on the favourite Ciceronian use of _nullus_ for _non_ see 47, 141, and Madv. _Gram._ 455, obs. 5. _Illud sit disputatum_: for the construction cf. 98; _autem_ is omitted with the same constr. in _D.F._ V. 79, 80. _Nusquam alibi_: cf. 50.
