But beside these, we find in the folio four other plays of a different kind, of which the most that any critic ventures to assert is that they were retouched, improved, and enlarged by Shakespeare. Of two of these, namely The Second and Third Parts of Henry VI. this would seem to be the truth; for we have the two plays in their original form, and there can be little doubt that it was them chiefly that Green had in view in the passage quoted above from his Groat's Worth of Wit, &c.; and upon examination it appears that in the first of them Shakespeare's additions and improvements amount to a fifth, in the second to only an eighth part of the text. Of the other two, The First Part of Henry VI. and Titus Andronicus, after a very careful study of them, my decided opinion, and apparently that of Mr. Dyce also, is that, with an exception presently to be noticed, neither the one nor the other contains a single speech or even a single line from the pen of Shakespeare. How they got into the folio is a question not easy to answer. Heminge and Condell, no doubt, may not have been critics, and so may have fancied that he had had to do with The First Part of Henry VI. also; or they may have merely inserted it as being connected with the other Parts. As to Titus Andronicus, I have already given a reason for its appearance in Meres's list. He had probably heard that it was by Shakespeare, and he made no exact inquiry, and so ascribed it to him; and the editors of the folio may have taken it on his authority, or have followed the same tradition. I do not believe that it was at any time in Shakespeare's nature to write the horrors of one of these plays, or to treat the noble Maid of Orleans as she is treated in the other, or even to labour on and improve the pieces that contained them. Besides, there are nowhere to be found plays more entirely of one single cast than these are. There is also displayed in them an acquaintance with Horace and others of the ancient Classics which Shakespeare did not possess. They may have been written by either Kyd or Marlow, each of whom had this acquaintance, and also a taste for horrors, and abundant talent for their composition. At the same time I think it possible that, as there is a Clown in Titus Andronicus--the only instance I believe out of the plays of Shakespeare--the two short, trifling, and needless scenes in which he appears may be from our poet's pen, and that hence the play was hastily ascribed to him.
