,To his surprise, many such candies did. contain significant quantities of lead, but the foils in which they v/ere marketed were lead freel .

Of the 19 blood samples completed the lead concentration of 8 are definitely in the range consistent with symptoms and Intoxica tion, The lead concentration pf another 5 of the blood samples are at the very upper limit above which symptoms may occur, and the lead concentration in the remaining 6 are within a "safe" area but, none the less, as a group would suggest Increased lead absorption.

The two lead materials handled were Epistatic 112 and Cyastab 988.

Without lead-lined equipment, tlie corrosive attack" of_ processing liquors would be even more troublesome than they are at'present
