(The intake of lead in food and beverages of the subject and his output of lead in the feces and urine had been followed day by day for a prolonged period prior to the initiation of this experiment, so that the pattern of his metabolism of lead was well known.

The reason back of this safety is that the lead content of the gasoline is so low that, ('/ } there i~ ao measurable absorption o lead during contact of the gasoline with the nkin, and (Z) the vapor given off from gasoline in open containers contains only negligible amounts of lead.

There is no evidence that leaded gasoline is more irritating than ordinary gasoline.
