Take, for instance, such a line as the eleventh of Comus, which Prof.Masson gives as:-- Amongst the enthroned gods on sainted seats.
A reader not learned in Miltonic rhythms will certainly read this Amongst th' enthroned gods But the 1645 edition reads: Amongst the enthron'd gods and so does Milton's manuscript.

Again, in line 597, Prof.
Masson reads: It shall be in eternal restless change Self-fed and self-consumed.

If this fail, The pillared firmament is rottenness, &c.
But the 1645 text and Milton's manuscript read self-consum'd; after which word there is to be understood a metrical pause to mark the violent transition of the thought.
Again in the second line of the Sonnet to a Nightingale Prof.Masson has: Warblest at eve when all the woods are still but the early edition, which probably follows Milton's spelling though in this case we have no manuscript to compare, reads 'Warbl'st.' So the original text of Samson, l.

670, has 'temper'st.' The retention of the old system of punctuation may be less defensible, but I have retained it because it may now and then be of use in determining a point of syntax.

The absence of a comma, for example, after the word hearse in the 58th line of the Epitaph on the Marchioness of Winchester, printed by Prof.Masson thus:-- And some flowers, and some bays For thy hearse to strew thy ways, but in the 1645 edition:-- And som Flowers, and som Bays, For thy Hears to strew the ways, goes to prove that for here must be taken as 'fore.
Of the Paradise Lost there were two editions issued during Milton's lifetime, and while the first has been taken as our text, all the variants in the second, not being simple misprints, have been recorded in the notes.
