What he has done, however, is to influence the thinking of legislative leaders and medical people who up until now apparently have been confused about tetraethyl lead and lead oxide since much of their information seems to come from Mr.

The interesting thing however is the variety of industries and variety of prod ucts into which this tonnagr of lead enters In the first place over 40 percent of all the lead used last year went into chemical compounds like *hite lead red lead, litharge, IJ-2 * a.-1 LIA23769 black oxide* lead silicate* lead chrvmates and tetraethyl lead !

It seemed unlikely that this was the case since tetraethyl lead is not as irritating to the skin as is gasoline.
