TRANSCRIBER’S NOTES

  1. P. [173], the portions listed in “Potassium permanganate, oz. 111.; liquid formaldehyde, pint 1.” are unlikely to be correct. Did not alter the passage.
  2. Silently corrected obvious typographical errors and variations in spelling.
  3. Retained archaic, non-standard, and uncertain spellings as printed.
  4. Re-indexed footnotes using numbers.
