The counterpart of this requirement is that of determining the actual extent of the absorption of lead from the respiratory tract under a variety of conditions.

As X anticipated,the material passes through the alimentary tract with so little loss of absorbed lead (absorbed in the alimentary tract during passage), as to be detectable only in the form of a very minute and temporary elevation of the rate of the urinary lead output.

The concentration of lead found in the rust and scale on the inner surface of a tank used for the storage of leaded gasoline, after the removal of the fuel, water bottom and sludge, amounts to a few hundredths of 1 per cent.

Smith's report does not, in fact, contribute much, and the calculations of lead Intake from various sources are much too uncertain to be of any use.
