PLATE I.

CASE 1.-Hæmaturia and Dropsy after Scarlet Fever, p. 75.

FIG.

1.-Blood-casts; amorphous fibrine stained with hæmatin; blood-corpuscles. 2.-Granular casts containing epithelial cells, healthy; two compound granulecells; scales of epithelium from pelvis; one cast very transparent.

-

CASE II. Hæmaturia and Dropsy after Scarlet Fever followed by Uræmia, p. 80.

3.-Blood-casts; spherical epithelial cells. 4.-Granular casts containing epithelial cells; many compound granule-cells; granular casts containing only free nuclei; several grape-like clusters of nuclei; abortive or disintegrated cells.

5.-The same; the casts containing many clustered collections of resplendent granules of aggregated nuclei, as well as compound granule-cells; one granular cast containing free nuclei.

6.-Malpighian bodies and convoluted tubes from the cortical part of the kidney. Both appear to be stuffed with a fine granular exudation. The basement membrane is everywhere denuded of epithelium, and the torn extremities of the tubes exhibit the granular matter and abortive cells freely escaping.

CASE III-Hæmaturia after Scarlet Fever and Dropsy, p. 87.

7.-Fibrinous blood-casts; fibrinous flakes stained with hæmatin; scattered blood-discs and epithelial cells, healthy.

8.-Granular casts containing normal epithelium and a few blood-discs; fibrinous flakes stained with hæmatin.

9.-Second attack of hæmaturia.-Fibrinous blood-casts; fibrinous flakes stained with hæmatin; epithelial cells; one compound granule-cell.

CASE IV. Scarlatinal Dropsy; recovery; p. 90.

10.-Fibrinous casts; two large compound granule-cells.

11.—Granular casts containing epithelial cells and blood-discs; one or two compound cells.

12.-Hyaline casts; a few scattered epithelial cells; resplendent granules; in all probability free nuclei; two compound granule-cells.

FIG.

CASE V.-Scarlatinal Dropsy, p. 94.

1, a.—Fibrinous cast containing blood-discs, and stained with hæmatin. b.-A cast containing only epithelial cells.

c. A granular cast, containing epithelial cells, blood-corpuscles, and compound granule-cells.

2.-Granular casts containing renal epithelium, and compound cells.

b.-Granular casts containing free nuclei, presenting the appearance of highly resplendent molecules. Compound cells (glomeruli).

c. Here and there aggregations of fat-molecules deprived of their cell-wall, as of a broken-up glomerulus.

3.-Microscopic appearance of the fluid pressed out from one of the cones. a. An epithelial cast.

b. Some epithelium from the straight tubes.

c. Some compound cells; broken up glomerulus; many free nuclei and granular matter diffused through the field.

4. From the cortical part of the kidney. It represents a Malpighian body and tubes filled with a dark granular deposit or exudation. A convoluted tube partially deprived of its epithelium; its interior filled with a dark granular exudation-compound cells, free nuclei, and disintegrated cells.

5.-Tubes teazed out from the base of one of the cones. One part of the canal seems choked with granular exudation and detached epithelial cells. The basement membrane at one part seems entirely deprived of epithelial lining.

CASE VII.-Acute Bright's Disease, p. 115.

6, a. Fibrinous blood-cast.

b.-Granular casts containing blood-discs and epithelial cells already becoming abortive. Many free nuclei.

7.-Granular casts containing epithelial cells, compound granule-cells, clusters of nuclei, and scattered blood-discs.

8. The casts becoming less granular, the epithelial cells more abortive and fatty, many free nuclei, and grape-like clusters, as if deprived of the cellwall.

9.-Casts becoming more hyaline, the epithelial cells more abortive; many compound granule-cells and free and clustered nuclei.

10. The casts quite or nearly transparent, studded with compound granule-cells, free and clustered nuclei, evidence of the extent of the disintegration of cell-structure.

11.-A portion of the cortical part of the kidney, teazed out with needles. The Malpighian bodies and convoluted tubes, appear filled with a granular exudation, with which is mixed abortive cells, free nuclei, compound granule-cells, and clusters of fat-granules. The epithelial cells seem to have been broken up or destroyed, and the tube filled with their débris. Here and there normal epithelium is still adherent to the basement membrane.

12.-Granular casts from a case of cardiac and pulmonary dropsy; early stage of albuminous urine, caused by simple blood stasis.
