and I sensibly find it to have twice so much; but when one sounds after the other, if the former be short, the latter long, how shall I detain the short one, and how, measuring, shall I apply it to the long, that I may find this to have twice so much; seeing the long does not begin to sound, unless the short leaves sounding? And that very long one do I measure as present, seeing I measure it not till it be ended? Now his ending is his passing away. What then is it I measure? where is the short syllable by which I measure? where the long which I measure? Both have sounded, have flown, passed away, are no more; and yet I measure, and confidently answer (so far as is presumed on a practised sense) that as to space of time this syllable is but single, that double.
