Indeed,in the latter it marks the beginning of the end, and cases of contracted kidney inwhich it is found will usually terminate fatally within one year. The Fibrinous Cast.—This misnamed cylinder resembles the waxy castsave in color. It is always yellow or even brown, deriving its color from bloodpigment, and, as might be expected, points to an active or subsiding inflammation;ordinarily to acute Brights disease. The Blood Cast, and the Brown Granular Cast.—This points to acuteinflammation as does the brown (dark) granular cast. If, as is usually the case, the cast carries washed-out cells (abnormalblood) it indicates slow effusion of blood or its high origin; if normal blood,more abundant hemorrhage or an origin in the straight tubules or Granular casts. Light and dar£. The dark granular cast is actually a blood-pigment cast. The Finely Granular Cast.—The special significance of this common formhas been discussed together with that of the hyaline cast. The Coarse Granular Cast.—This is usually associated with fibrinousor waxy casts. The Fatty Cast.—This is most frequently seen in convalescent cases of acutenephritis, or in chronic parenchymatous nephritis. True Epithelial Casts.—These occur only in active or subsiding, acute orsubacute inflammation, in acute Brights disease, or the subacute exacerbationof a chronic parenchymatous nephritis. Many casts carry here and there an epithelial cell and should be sodescribed in case reports, yet these cannot properly be called epithelial casts. Pus Casts.—These are found in suppurative disease of the kidney or in THE EXAMINATION OF THE URINE 243 pyelitis extending to the straight tubules and frequently require tre
