ever follow, when the lead is combined
with tin; because this metal, being more eager for oxidation, prevents
the solution of the lead.

When we consider the various unsuspected means by which the poisons of
lead and copper gain admittance into the human body, a very common but
dangerous instance presents itself: namely, the practice of painting
toys, made for the amusement of children, with poisonous substances,
viz. red lead, verdigris, &c. Children are apt to put every thing,
especially what gives them pleasure, into their mouths; the painting of
toys with colouring substances that are poisonous, ought therefore to be
abolished; a practice which lies the more open to censure, as it is of
no real utility.
