3: Tenn Pounde
longways (?), the more the merrier
mms pages 5 and 6
Playford version: from 4th edition to 16th edition.
Music: Track 2 (4th in the medley) of The Food of Love by various artists - the tune seems to be AAB, where A=8 beats and B=16 beats.  How that works with what is below I do not know.
Part 1
Verse 1, Part A
1: Lead up [a double]
2: [Fall back a double]
Verse 1, Part B
1: Lead up [a double]
2: [Fall back a double]
Chorus 1
"Fall down presently into the middle of all the rest, with your lady hand in hand" - so, first couple leads the others down the middle of the set?  But how far? 
"and then round softly (or as you please) hand in hand" - perhaps everyone circles slowly/softly (or maybe faster/harder)?
"and then they" - here the instructions vanish, cut off abruptly.  
Part 2
Verse 2, Part A
1-2: Side [left to line up right shoulders]
Verse 2, Part B
1-2: Side [right to line up left shoulders]
Chorus 2
"and the same agayne" - so the chorus does not change.  But what comprises the full chorus?
Part 3
Verse 3, Chorus 3
"And soe the 3d time" - but repeat what?
"and if you please each doe his part" - which seems to be more of an informal ending phrase, rather than an instruction for continuing the dance.
Comparison to the Playford version (version 1, 4th to 16th editions)
Version 1 of Ten Pound Lass is a longways for 8 with the last two couples improper.  This is a "for as many as will" dance, and I'm not even sure that it isn't a huge circle dance, rather than a line dance.
None of the choreography matches at all, not verse nor chorus (or at least what we know of the chorus).
I can't say that this is a match to Version 1 of Ten Pound Lass.
Comparison to the Playford version (version 2, 17th and 18th editions)
Version 2 of Ten Pound Lass is a for as many as will virus-progressive with only one figure, but this figure involves 2 couples at a time going through each other in just about every permutation possible.
As such, it doesn't seem as if it matches this dance (as much as we know of it), so I wouldn't say that these are the same dance either.
There seems to be something wrong in the manuscript.  Page 5, which contains the beginning of the dance, has a large blank space at the end, which is unusual.  The last bit of the last sentence is obscured, but
the phrase "they the(n?)" implies something more to come.  However, page 6 begins with a section marker, not the continuation of the sentence.  The dance instructions are therefore incomplete.
However, this dance doesn't seem to be any kind of match to "Ten Pound Lass" of any version from Playford.  It seems to be a totally different dance entirely.
