There being no significant evidence of a response to this exposure to 10 micrograms (approximately half of each 24-hour period), it is evident that the concentration of lead in the chamber will have to be increased, and that the experiment will have to go cm for somewhat more than a full year from the middle of this year in order to provide the points on a curve from which an extrapolation can be made to the effects (on the urinary excretion of lead and on the lead content of the blood) of exposure for 24 hours per day every day.

Composite materials such as lead and concrete, lead and earth, or lead and steel are other structural possibilities.
