s ofbacteria and not to B. coli. We havestudied the so-called hematogenous kid-ney pyelograms to determine whetherit is possible to recognize abscesses inthe cortex or the pyramids of the kidney.The result has not been totally satisfactory.It is possible, however, to recognize in 636 The Roentgenologist and the Urologist in the Diagnosis of Renal Disease some cases definite areas in which theinjection material in the neighborhoodof the calices is either flattened or ex-tends into the cortical substance. Theseabnormalities have been proved to bethe sites of abscesses usually situated in thepyramids. I believe in great measure thesuccess of pyelography in these cases outside of the line of the calices abovereferred to. Irregular granular calcificationin the kidney should lead one to suspecttuberculosis in these cases. There is anoccasional cortical stone formed withinthe substance of the kidney, often in amalformed pelvis or calyx, which must bedifferentiated because it lies outside the
