    I'm guessing that by "abb" you mean abbreviation, but what is a "mansc"? If you want a clear answer, please don't write your question in code. – mikeagg Aug 28 '15 at 15:33
  • @StoneyB - Following your comment I reworded my (deleted) comment as follow: I could only decypher the word "brute" that refers to a gross weight. Some samples are extracted from the bale, heated and weighted after deshydration. Then, the "absolute" weight is deduced from the bale brute weight according to deshydration results. – Graffito Aug 28 '15 at 18:19
  • @Graffito NMF; but it appears from this that a standard 11% moisture is added back to dry weight -- or was at the turn of the 20th century. – StoneyB Aug 28 '15 at 18:33
  • @StoneyB - Yes, these 11% are mentionned in a French decree dated April 5th 1805 (precisely "23 germinal an XIII"). – Graffito Aug 28 '15 at 19:41

I think these are 'cwt', 'qr' and 'lb', representing 'hundredweight' (112 pounds), 'quarter[-hundredweight]' (28 pounds) and 'pound' in the avoirdupois system.

Here is a table from T.H.Babcock, *The Practical Arithmetic ... *, 1829:

'Brute' is what we would today call 'gross' weight.

  • +1, but I'm curious why a "quarter" is 28 pounds and a "hundred weight" is 112 pounds (not 100). Is it only so that the metric system will have something to laugh about? – Robusto Aug 28 '15 at 16:08
  • @Robusto It's a very long and complicated history which in England alone involved continual adjustments between various standards - Tower weight, troy weight, avoirdupois weight - which themselves fluctuated over time. It's even more complicated when the "standards" of other nations are brought into play. I urge you to stifle your curiosity, or you may go mad. – StoneyB Aug 28 '15 at 16:18
  • I'm afraid it's too late. – Robusto Aug 28 '15 at 16:30
  • @Robusto Oh, dear. Well, you can start with the Wikipedia articles on avoirdupois and troy, and move on to its discussions of pound, mark, shilling, penny, grain. If you're still standing after that you can mess around with continental and classic measures, too. And then you'll want to get into some of the archaeological studies. ... Been nice knowin ya. – StoneyB Aug 28 '15 at 16:43

    @Robusto The Short hundredweight was 100lb used mainly in US and Canada. The Imperial or Long hundredweight was 8stones (1st = 14lbs) – Joe Dark Aug 28 '15 at 17:46
