Dear Bob
T.M.L
I enclose for your information copy of a recent exchange of correspondence with our Agents in Japan.
We have purposely refrained from giving them any detailed information in the belief that this will have already been provided to M.I.T.I. through either or both Ethyl Corporation and Dupont.
Looking forward to seeing you in October.

Dear Sirs*
Vie acknowledge receipt of your letter No* 60-215 of the 3rd September in which you refer to information on
Tetramethyl Lead which has been requested by M.l.T.I's Petroleum Section* .
As you are aware this material at the present time is supplied from sources available to us in the United States. Vie presume therefore that M.I.T.I. will already have received the
answers to their- questions from the manufacturers in the U.S.A. and it would not appear to us to be necessary to repeat the technical information in their possession*
Nevertheless the answers to the questions you have posed are as follows*
1* TetraMethyl Lead does not appear to be any more toxic than Tetraethyl Lead which is currently being used in gasoline in Japan.
2* The chemical formula of T*M*L* is as follows*
Pb(CH3>4
3* The subsequent state of T.M.L. when blended vrlth gasoline is a homogeneous mixture, though precipitation may take place after long periods of storage in
approximately the same manner as may occur with T.E.L*
4* The maximum concentration of T.M.L. in Motor gasoline permitted under our Terms of Supply is as follows*
N9637.01 l Kg' 0008231
Motor gasoline shall not contain more than*
0.54 ccs of T.M.L* per litre 2.05 ccs of T*M.L. per U.S. Gallon 2.46 ccs of T.M.L. per Imperial Gallon

1. All information and data regarding the toxic character of T.M.L.
2. The chemical formula of T.M.L.
3. State subsequent to the blending of T.M.L. with Gasoline (i.e. whether it remains blended or becomes separated).
