Jess’s Book Cipher

From Shakespeare’s A Midsummer Night’s Dream, it’s the Book Cipher Jess constructs to use in The Darwin Code. Can you decode the replies before Ben, Freddie and Jess?

If we shadows have offended,
6 7 8            9 10        11 12
Think but this     and all        is mended,
13 14 15      16  17 18
That you have  but slumbered here
19 20 21 22 23
While the visions did appear.
24 25 26        27         28 29
And this weak    and      idle theme,
30 31 32 33        34 35
No more yielding but        a dream,
36              37 38 39  
Gentles, do not reprehend:  
40 41 42 43        44 45
If you pardon, we       will mend:
46 47 48    49    50 51 52
And, as I     am     an honest Puck,
53 54 55 56 57
If we have unearned luck
58    59 60           61 62 63
Now  to ’scape   the serpent’s tongue,
64 65 66 67 68    69
We will make amends ere  long;
70 71 72          73  74        75
Else the Puck      a liar call;
76 77 78        79        80 81
So, good night  unto    you all.
82     83 84        85 86    87     88  89
Give  me your   hands, if     we     be  friends,
90 91 92 93 94
And Robin shall restore amends.
