mora, ‘by slow degrees.’ Cf. I. 402 (of stones turning to men), mollirique mora, XV. 362, quaecumque mora (by ‘keeping’ as we say), fluidove calore corpora tabuerunt.
fracta dehiscit, ‘cracks and parts,’ Cf. 412 n. Fracta, for tacta of MSS. is due to Heinsius. [Can.7 has tacta corrected from tracta. May not tracta be right? ‘draws in and splits open,’ or perhaps ‘collapses and splits open.’ It is very difficult to imagine an original fracta becoming either tracta or tacta. R. E.]
