'j Clinically, 1 felt he had sustained a temporary anesthesia subsequent to the inhalation of petroleum hydrocarbons add that he probably had not absorbed a hasardous amount of lead.j I took urine and blood samples for quantitative determination of lead concent < advised you to keep liirn under observation attthe hospital at least 2k hours The laboratory reported the following values; brine Blood 0.03 cjgja Fa per liter 0.03 mgs Fo per 100 m.l.
