Note 53 tri — Chapter XX · SULPHUR, SELENIUM, AND TELLURIUM

These data (as well as those in the following table) have been recalculated by me chiefly upon the basis of Kremer's, Pickering's, Perkin's, and my own determinations; all the requisite corrections have been introduced, and I have reason for thinking that in each of them the probable error (or difference from the true figures, now unknown) of the specific gravity does not exceed ±0·0007 (if water at 4° = 1) for the 25–80 p.c. solutions, and ±0·0002 for the more dilute or concentrated solutions.
