S*fa first of these - lead poisoning should b completely eliminated on the ground that there is no evidence of a suggestive exposure to lead compounds, there is no evidence that lead absorption ocourod and moreover, the cl'nical findings wore not in any way characteristic of lead poisoning* The only suggestive evidence of lead absorption consists in the fact that on of the physicians stated that he observed a lead line on the gums* This lead line was apparently fleeting and it occurred at a time when on Sould have expec ted some degree of congestion of the g ^ margin* It is my experience that the bluish appearance of the gums is often present and that sometimes it is quit difficult through the us of ordinary technique, to differentiate the blueness of congestion ahd the blueness of 'lad Xihe* In fact, unless one compresses the gum and looks with a hand lens and establishes the fact that the blue* ness is punctate in character, one is not certain whether or not a lead line actually exists* It has been said that a lead analysis of the urine at the tira of the symptoms , failed to demonstrate the presence of lend* Such evidence I an sorry to say is of little consequence sinoe the volume to find amounts of lead which arc normally present in the urine indicates that the technique of the examination was faulty, or that the quantity of the sample examined was . inadequate* Nevertheless, in view of the clinical and experimental .evidence...which is available, I think we shall have to conclude that lead poisoning is the most unlikely interpretation of this man*a Illness* i:. : .
