The natural log of blood lead was more normally distributed, was more statistically significant, and gave a higher r 2 than untransforned blood lead, blood-lead-squared, blood lead plus blood-lead-squared, the square root of blood lead, or blood lead to other fractional power

O) The natural lead content of soils varies widely.

A long term comparison of lead, in and out, as measured by the experimental procedures shows that over a long duration lead in{Pbl)is approximately equal to lead out (Pbo).

Those who excreted abnormal amounts of lead in the urine frequently exhibited ILcad compounds {lead vinyl stabilizers) were as follows: basic lead silicate sulfate, 68.0 per cent total lead; dibasic lead phosphite, 90.8 per cent total lead; dibasic lead phthalate, 79.8 per cent total lead; lead chlorosilicate complex, 47.5 per cent lead; and dibasic lead stearate, 55.3 per cent total lead. 780 THE NEW ENGLAND JOURNAL OF MEDICINE Oc- 1963 T a b l e 1.

The comparison of the white lead mixed pigment primer applied under a lead-free finish coat; and the lead-free paint, selfprimed, emphasizes the superior performance of the "lead" primer.

National Lead Company is also a de pendable source of supply for lead oxides ...red-lead, litharge and orange mineral.

Thus their sign for Saturn, b lead.
