ses minute fat-globules appear in the pus-cells, and thewhole cell may be replaced by them. This is never foundin acute inflammations, and the more fat-globules arefound, the more chronic the process is, in all probability.Pus-cells may contain rust-brown crystals of hematoidinin the form of needles or flakes, especially in cases in whichpyuria is accompanied by hemorrhage. Dark-brownpigment-granules may be found in these cells in chroniccystitis. Very rarely pus-cells may show delicate cilia,showing their origin from the epithelia of the uterus (endo-metritis) . The pus-cells in the urine may be derived from thekidney or its pelvis, the ureters, the bladder, the urethra, 282 EXAMINATION OF THE URINE or from the rupture of an abscess into some portion of theurinary tract.

When they arevery numerous, the diagnosis of suppuration may be made,provided the other features of the urine corroborate it. pus 283 The presence of pus having been determined, the nextstep is to find its source, and the only way to do this is tostudy the other elements of the sediment, such as epithelia,casts, etc., which accompany the pus. Pus from the kidney may be found in any inflammatoryor suppurative condition of this organ. A few cells willbe found in simple irritation and in non-suppurativenephritis, showing that the pus-cells ar
