Previously unrecorded variation in Cambridge MS of New Arcadia?

I have not yet made a complete review of the literature on the topic, but it seems likely that the Cambridge Manuscript of Sidney’s New Arcadia, Cambridge University Library MS Kk 1.5, features a previously undocumented variant in one of Sidney’s greatest and goriest descriptions of battle. Sidney’s catalogue of soldiers’ bodies mutilated in Basilius’ siege of Amphialus’ castle in book three, on f. 165r, mentions “heads dispossessed of their natural seignories… [and] bodies to see to, but that their hearts, wont to be bound all over so close, were now with deadly violence opened” (The Countess of Pembroke’s Arcadia, ed. Victor Skretkowicz [Oxford, Clarendon Press, 1987], 340-41). The Cambridge manuscript omits “bound over” and replaces it with the Arabic numerals 7, 9, 10, and 3.  Below I include a transcription and a screenshot of the passage in question. I’d love to hear from anyone who has an idea about this oddity.

Musical Settings of Arcadia Songs (Edward Plough, Kevin Carney)

We’re proud to announce that we’re beginning to make available recordings of newly set Arcadia songs in connection with Sir Philip Sidney’s Arcadia: A Restoration in Contemporary English of the Complete 1593 Edition of The Countess of Pembroke’s Arcadia (The Parlor Press 2017). Edward Plough (SUNY Farmingdale) is composing and performing the new settings, and and Kevin Carney is producing them. Here’s a taste of what’s coming: in the middle of Book Two, the lovesick and sexually confused Princess Philoclea sings her lament “Over these brooks” (Parlor Press edition p. 214).
