_TCD._ A large manuscript in the Library of Trinity College, Dublin, containing two apparently quite independent collections of poems--the first a collection of Donne's poems with one or two additional poems by Sir John Roe, Francis Beaumont, Sir Thomas Overbury, and Corbet; the second a quite miscellaneous collection, put together some time in the thirties of the seventeenth century, and including some of Donne's poems. It is only the first of these which belongs to the group in question. These four manuscripts are closely connected with one another, but a still more intimate relation exists between _A18_ and _TCC_ on the one hand, _N_ and _TCD_ on the other. _N_ and _TCD_ are the larger collections; _A18_ and _TCC_ contain each a smaller selection from the same body of poems. Indeed it would seem that _N_ is a copy of _TCD, A18_ of _TCC_. _TCD_, to start with it, is a beautifully written collection of Donne's poems beginning with the _Satyres_, passing on to an irregularly arranged series of elegies, letters, lyrics and epicedes, and closing with the _Metempsychosis_ or _Progresse of the Soule_ and the _Divine Poems_, which include the hymns written in the last years of the poet's life. _N_ has the same poems, arranged in the same order, and its readings are nearly always identical with those of _TCD_, so far as I can judge from the collation made for me. The handwriting, unlike that of _TCD_, is in what is known as secretary hand and is somewhat difficult to read. What points to the one manuscript being a copy of the other is that in 'Sweetest Love, I do not go' the scribe has accidentally dropped stanza 4, by giving its last line to stanza 3, and passing at once to the fifth stanza. Both manuscripts make this mistake, whereas _A18_ and _TCC_ contain the complete poem. In other places _N_ and _TCD_ agree in their readings where _A18_ and _TCC_ diverge. If the one is a copy of the other, _TCD_ is probably the more authoritative, as it contains some marginal indications of authorship which _N_ omits.
