The folio Leyden manuscript by a happy chance has marked the exact number of verses, viz. eight, which have been lost after i, 1093. As a casual reader of Lucretius may have perhaps but a confused notion of his argument in this place owing to the stupid negligence of Havercamp and the carelessness of so many previous editors who tacitly adopted Marullus' unmeaning inter- polation, I will venture to supply the eight missing verses. What their general drift was cannot be doubtful. First of all the sentence left incomplete by the words Nisi a terris paulatim cuique cibatum has to be finished ; then must have followed an apodosis to the long protasis begun at 1083 by Prceterea quoniam &c, and this apodosis must have asserted that the argument of the Stoics was not only false as shewn in 10521082, but also self-contradictory ; then must have commenced the Epicurean answer to the whole Stoic argument which began at 1052, and this answer must have joined on to the words Ne volucri riiu flammarum #c. This then is the way I would presume to com- plete what is wanting : 1094 dcedala sufficiat rerum natura creatri.r, scilicet incerto diversi errore vagantes argumenta sibi prorsum 2)itgnantia Jingitnt.
