In a recent issue of The Journal Trumper and Gordy1 report an interesting case of lead poisoning under the title "Lead in a Renal Calculus" in which a calculus was removed from the right ureter. This calculus was of the phosphatic type and contained 3 per cent of lead. The urine when analyzed was within the so-called normal range. The writers say "As far as we have been able to learn from a careful search of the literature there has been no previous report of a urinary calculus which contained lead."
Some years ago I carried on a fairly extensive spectroscopic investigation of the metallic content of animal and human tumors. Traces of lead were frequently found. Other investigations showed that the source of this lead was in the food and drinking water. Traces of lead could be found in the water supply of the city of New York
