Our purpose is to present in brief form the postmortem protocols, the microscopic reports and the chemical analyses of four cases of an occupational disease acquired during the manufacture of so-called tera-ethyl lead. It is not our intention to discuss the dangers involved in the manufacture of tetra-ethyl lead or the dangers of the liquid used as an antiknock agent, the ethyl gasoline. We have made no experiments concerning the toxicity of the substance itself or of the ethyl gasoline.
A paper dealing with the clinical histories of the four cases presented here is in preparation by Dr. Gilman Thompson and his associates in the Reconstruction Hospital of New York; we are indebted to them for the privilege of studying the clinical histories.
