The last three lines have got me baffleissimused.
11. conturbabimus illa, ne sciamus,
12. aut ne quis malus invidere possit
13. cum tantum sciat esse basiorum
11. We will jumble those things (what things?), so that we may not know,
12. nor so that someone may cast an evil eye,
13. when he may know so many kisses to be..
As you can see I haven't a clue what it means.
