M. Tycho Mommsen published in 1859 a reprint of the first and second Quartos on opposite pages, and in the footnotes a collation of the remaining Quartos (not quite complete in the case of the fourth and fifth), the four Folios, Rowe's first edition, and the new readings of Mr Collier's MS. corrector. The volume is preceded by learned and valuable 'Prolegomena,' and the collation, which we have tested, is done with great care and accuracy. If our collation, so far as it occupies the same ground, may claim to be not less accurate, it must be remembered, first, that we have not endeavoured to record every minute variation of typography, but only such as were in our judgement significant or otherwise noteworthy; secondly, that we have had in all cases the original editions to refer to; and thirdly, that we have had the advantage of comparing our collation with his, and, wherever we found a discrepancy, verifying by a reference to the old copies. Of the many alterations of _Romeo and Juliet_ we have only had occasion to quote Otway's _Caius Marius_. * * * * * 2. TIMON OF ATHENS was printed for the first time in the Folio of 1623. It is called _The Life of Tymon of Athens_; in the running titles, _Timon of Athens_; and occupies twenty-one pages, from 80 to 98 inclusive, 81 and 82 being numbered twice over. After 98 the next page is filled with _The Actors Names_, and the following page is blank. The next page, the first of _Julius Cæsar_, is numbered 109, and instead of beginning as it should signature _ii_, the signature is _kk_. From this it may be inferred that for some reason the printing of _Julius Cæsar_ was commenced before that of _Timon_ was finished. It may be that the manuscript of _Timon_ was imperfect, and that the printing was stayed till it could be completed by some playwright engaged for the purpose. This would account for the manifest imperfections at the close of the play. But it is difficult to conceive how the printer came to miscalculate so widely the space required to be left. The well-known carelessness of the printers of the Folio in respect of metre will not suffice to account for the deficiencies of _Timon_. The original play, on which Shakespeare worked, must have been written, for the most part, either in prose or in very irregular verse. * * * * * 3. JULIUS CÆSAR was published for the first time in the Folio of 1623. It is more correctly printed than any other play, and may perhaps have been (as the preface falsely implied that all were) printed from the original manuscript of the author. The references to Jennens in the notes are to his edition of _Julius Cæsar_, 'collated with the old and modern editions', and published in 1774. * * * * *
