This paper also had three excellent references to previous work' done, on this subject,* one of which was co-authorod. by Dr. Kehoe. ; 1/suggested that he write Dr. Kehoe telling him of their problem, and asking specific questions on the phases .which are giving him trouble, as an indication of how minut the concentrations of hydro-bromic acid (if it exists at all) and lead oxide would b in exhaust fuses, I oointsci out that even at-the maximum allowable concentration of 3 *.l -vr gallon and air fuel ratio of 12 to 1, there cools only be about 1 part in.10,000 of products resulting from TEL.
