Note 990 — BOOK XXXIII. THE NATURAL HISTORY OF METALS.647

Ajasson thinks it possible that the “chrysitis,” or “golden” litharge, may have been the yellow deutoxide of lead; the argyritis, or “silver” litharge, the white variety of the same deutoxide; and the “molybditis,” or “leaden” litharge, a general name for sulphuret of lead and silver; of lead and antimony; of lead, antimony, and bismuth; and of lead, antimony, and copper. Or perhaps, he thinks, they may have been the respective names of yellow or golden litharge, white or silver litharge, and terne. With the latter opinion Delafosse seems to coincide.
