In May of 1959, the preliminary experiment involving the use of tetrainethyllead was initiated in San Francisco, California and was completed some months later, as described in detail in a Report of the Kettering Laboratory, dated November 10, 1959 and entitled "An Investigation of the Potential Hazards of Exposure to Lead Associated with the Handling and Use of Gasoline Containing an .Antiknock Fluid in Which Tetramethyl lead is Substituted for Tetraethyl Lead."

Tetraethyl lead has Ions been accepted generally as a valuable additive to gasoline for use in automotive and aeronautical gasoline, and satisfactory aeons have been found for the control of all of the occupational canards that have boon associated with its production, its transportation, ana its udditieri to gasoline.

Ethyl Fluid is the concentrated, commercial fluid containing tetra-ethyl lead and other ingredients;'which is to be added to gasoline to make ethyl gasoline.

Ethyl Fluid is the concentrated, commercial fluid containing tetra-ethyl lead and other ingredients;'which is to be added to gasoline to make ethyl gasoline.

Tetraethyl lead has long been accepted generally as a valuable additive to gasoline for use in automotive and aeronautical gasoline, and satisfactory means have been found for the control of all of the occupational aasuras that have boon associated with its production, its transportation, ana its addition. to gasoline.

This record is not bad, considering that several million tons of t e l have been manufac tured and distributed since 1926.
