§128. _Agi secum_: cf. _nobiscum ageret_ in 80. _Simile veri_: cf. 66. _Notionem_: = _cognitionem_, επιστημην. _At paulum_: MSS. _et_ Halm _sed._; cf. _at illud ante_ in 116. _Si quae_: Halm and many edd. have _se, quae_. But the _se_ comes in very awkwardly, and is not needed before the infinitive. Madv. indeed (_Em._ 114), after producing many exx. of the reflexive pronoun omitted, says that he doubts about this passage because _considero_ does not belong to the class of verbs with which this usage is found, but he produces many instances with _puto_, which surely stands on the same level. _Non magis_: so in 119 _nec magis approbabit nunc lucere_, etc. The sunlight was the stock example of a most completely cognisable phenomenon; hence the Academics showed their hostility to absolute knowledge by refusing τον ‛ηλιον ‛ομολογειν ειναι καταληπτον (Galen _De Opt. Gen. Dicendi_ 497 B qu. P. Valentia 304 ed. Or.). _Cornix_: for the Stoic belief in divination see Zeller 349--358. _Signum illud_: the _xystus_ (9) was adorned with statues; edd. qu. Plin. _Nat. Hist._ XXXIV. 8. _Duodeviginti_: 82, I just note that _octodecim_ is not used by Cic. _Sol quantus sit_: 91. _Omnium rerum ... comprehendendi_: not a case of a plural noun with a singular gerund like _spe rerum potiendi_, etc., but of two genitives depending in different ways on the same word (_definitio_).

For the turn of expression cf. _T.D._ IV. 62 _omnium philosophorum una est ratio medendi_, _Lael._ 78 _omnium horum vitiorum una cautio est_, also 51 of this book.
