larger proportion of the organic lead in the sludge vas tetraethyl lead.

(The term "ethyl gas" is a colloquialism which, at present would be spoken of as "leaded gasoline" or, better, gasoline containing tetraethyl lead.)

With respect to the potential absorption of tetraethyl lead, as differ entiated from that of inorganic lead compounds, there are no blood changes of any kind that have any relevance Wo such changes occur even in fatal tetraethyl lead intoxication.

We have come to recognize that pollutant lead levels on a world-wide scale are tens to thousands of times larger than natural lead levels, and that the route: ore lead, to tetraethyl lead, to atmosphere, to seas is of major importance.

Gonzalez, concerning the handling of small shipments of tetraethyl lead from the Detroit Laboratory.

Over all the problem does not differ substantially from that presented by Tetraethyl ^ead and it is intended to apply the same safety recommendations in respect of manufacture and distribution as applied to Tetraethyl Lead at the present time.

The concentrations employed by the Army are not in excess of k cc of tetraethyl lead per American gallon.

The rathor gross discrepancy between the concentrations in the blood and urine is characteristic to some degree of the behavior of tetraethyl lead.

They have further informed me that certain suppliers of antiknock compound propose to manufacture and sell compounds containing tetramethyl lead and that certain refiners would like to use them because their use provides certain technical and economic advantages over compounds containing tetraethyl lead.

The rather gross discrepancy between the concentrations in the blood and urine is characteristic to some degree of the behavior of tetraethyl lead.

If I am mistaken in this assumption, I should like to know, sines, as you may be aware, we have undertaken to keep a very close watch on all situations that lead to hazard in the handling of-tetraethyl lead or leaded gasoline.
