Dr* Teegarden himself was apparently never convinced of the correctness of this diagnosis and when I discussed with him the observations which had been made over a period of years on the magnitude of exposure associated with leaded gasoline* he apparently became convinced that lead was not the tiologie factor* : - t si .. `"A i i -i .' l ' However ho readily agreed fee obtain samples of bleed and ' for a farther amlysts at oar bands as a ebook m ....
