Quote:Given the clustering of the dates for the four Soxhlet treated samples, and the nature of the object (a book), one can argue that in fact, a single object was measured 4 times
Quote:Note that the measurement from solvent treated Leaf #68 was excluded from this average

"the measurement from solvent treated Leaf #68 was excluded from this average."
In fact it was the solvent untreated sample that was excluded.

Hence I conclude that the solvent extraction was used in all cases for the 4 final samples.
