The range of values for the lead concentration in the bones and other tissues of normal persons is not a3 clearly defined a3 one might wish* However one does know something of the quantities that have been found in the tissues of persons without exposure in the lead trades.

In order to expedite the studies on lead absorption and lead poisoning, the analytical facilities of tho laboratory have been enlarged and modified* Specially designed and dustproof laboratories have boon completed end are now in use* The distribution of fluorine in food materials and in the excreta of normal persons has been under study, an article on "Normal Urinary Fluorine B?

While the lead content of the sludge may be low, it 1 doubtful.if the total load content was materially reduced* It would seem logical that some lead would b carried off with the water if"the water bottom sore changed with ary degree of regularity* La the ease that earn to Batchelor* s attention, he mentioned that there, was but a trace of lead in the-sludge* ' -If-he has a. more accurate"-figure, - w should liks to have it and we should also like more information with regard to the amount of water held in the tank and the frequency with which it vac changed* ; ..

The analytical result, however, does establish that this man has had a severe exposure to lead p and that the severity was such that lead encephalopathy could have resulted.
