Changed "chrusos" to "chrysos" in the footnote on page 110: "(chrysos, gold and kolla, solder)."

The footnote on page 110 contains the reference "(see note xx., p. x)." Rather than Roman numerals, this appears to be a placeholder to a reference that was not filled in. Perhaps it should be "(see note 8, p. 560)," but it was left as is.

Changed "tinstone" to "tin-stone" in the footnote on page 110.

Changed "locks" to "blocks" on page 151: "blocks, and plates."

Something is wrong with the sentence on page 153 that ends with the reference to footnote 3. One metreta is larger than one-sixth of a congius. Perhaps "metreta" and "congius" should be swapped in this sentence, but it was left as is.

Changed "bail" to "bale" on page 153: "iron semi-circular bale."

Changed "Fosilium" to "Fossilium" twice in the footnote on page 155: "De Natura Fossilium."

Changed "Pig-skin" to "Pigskin" in the caption to the illustration on page 168: "Pigskin sacks."

Left "vapor" as is in footnote 20 on page 210 although it's spelled "vapour" everywhere else, because it's in a quote.

Changed "touchneedles" to "touch-needles" in footnote 37 on page 253: "detailed account of touch-needles."

The reference to page 259 in footnote 39 on page 253 does not seem to make sense, but was not changed. Perhaps the reference should be to footnote 27 on page 242.

In the table on page 257, the entries for the 20th and 21st needles do not add up, because the entry for the number of sextulae of copper belongs in the 21st needle, not the 20th. This was corrected. However, there are other errors in this table, which are not so obvious and were not corrected. In particular, the entries for the 22nd, 28th and 31st needles do not add correctly.

In the table on page 258, the number for the siliquae of copper was sometimes in the sextulae column. These were corrected. The affected lines were the ones for needles 13, 22 and 24. There is some other error (uncorrected) for the 17th needle; probably it should have another sextula of silver.

Filled in the missing "4" in the line for the 8th needle in the table on page 260.

Changed "52" to "25" in the line for the 3rd weight in the table for the "greater" weights on page 261.

Changed "Boussingalt" to "Boussingault" in footnote 18 on page 454: "Investigation by Boussingault."

Footnote 26, on page 465, refers to a discussion on page 389; there is no such discussion. Perhaps the note on page 390 was intended, but no change was made.

The reference to p. 480 in the footnote on page 466 doesn't seem to make sense. Perhaps the reference should be to the note on p. 475 or the illustration on p. 481, but it was not changed.

Changed "roman" to "Roman" in the caption to the figure on page 481.
