l. 6. _The skill of specular stone. _ Compare _To the Countesse of
Bedford_, p. 219, ll. 28-30:

You teach (though wee learne not) a thing unknowne
To our late times, the use of specular stone,
Through which all things within without were shown.

Grosart (ii. 48-9) and Professor Norton (Grolier, i. 217) take
'specular' as meaning simply 'translucent', and the latter quotes
Holinshed's _Chronicle_, ii. ch. 10: 'I find obscure mention of the
specular stone also to have been found and applied to this use' (i. e.
glazing windows) 'in England, but in such doubtful sort as I dare
not affirm for certain. ' This is the 'pierre speculaire' or 'pierre a
miroir' which Cotgrave describes as 'A light, white, and transparent
stone, easily cleft into thinne flakes, and used by th' Arabians
(among whom it growes) instead of glasse; anight it represents the
Moon, and even increases or decreases, as the Moon doth'. But surely
Donne refers to crystal-gazing.
Paracelsus has a paragraph in the
_Coelum Philosophorum_:

'How to conjure the Crystal so that all Things may
be seen in it.

'To conjure is nothing else than to observe anything rightly, to know
and to understand what it is. The crystal is a figure of the air.
Whatever appears in the air, movable or immovable, the same appears
also in the speculum or crystal as a wave. For the air, the water, and
the crystal, so far as vision is concerned, are one, like a mirror
in which an inverted copy of an object is seen. ' The old name for
crystal-gazers was 'specularii'. Mr. Chambers suggests very probably
that there is a reference to Dr. Dee's magic mirrors or 'show stone',
but one would like to explain the reference to the cutting of the
stone on the one hand, and its being no longer to be found on the
other.

l. 16. _Loves but their oldest clothes. _ The 'her' of _B_ is a
tempting reading in view of the 'woman' which follows, but 'their'
is the common version and the poet's mind passes rapidly to and fro
between the abstract and its concrete embodiments. The proleptic use
of the pronoun is striking in either case.
