Note 1240 — Chapter XVIII · OF POISONING WITH LEAD.

In distilled water containing a 12,000th of anhydrous arseniate of soda three lead rods weighing 71·235 grains became in thirty-three days 71·240; in a solution of a 15,000th the lead, though slightly whitened, retained its weight exactly, weighing at the end, as at the beginning, of the experiment 62·622 grains. In distilled water containing a 35,000th of anhydrous phosphate of soda, three lead rods, which weighed together 73·949 grains, became in thirty-two days 73·946; and in a comparative experiment with a solution containing a 27,000th they gained 0·015.
