§ Mr. Hugh Jenkins
asked the Secretary of State for the Home Department for how long baboons have been used in connection with the effects of lead in petrol; if they have suffered any ill-effects; if the use of these animals is continuing in such tests; and, if so, to what extent.
§ Dr. Summerskill
We are not aware from records that any experiments concerned with the effects of lead in petrol have been carried out on baboons in the United Kingdom but I will investigate any case known to my hon. Friend.
