and the kidney resulting is called the " small red 

 granular kidney" the " red contra ted kidn 

 and at times the " gouty kidney" ox the " arterio- 

 sclerotic kidney '." This kidne) i- usually much di 

 minished in size and weight; the capsule is greatly 

 thickened and adherent, so thai it < annul be r< mi 

 withoul tearing the kidnej tissue. The renal sub- 

 stano is reddish, granular, with small ind firm 



on section. Microscopically, there is found a great 

 increase in the interstitial dssue, reducing the caliber 

 of the tubules. This excess of fibrous dssue has given 

 origin to the name " cirrhotic kidney" and this form of 

 Bright'.-, disease i- frequently associated with gout, 

 syphilis, chronic lead poisoning, or alcoholic excess. 

 Albuminoid degeneration of the kidneys is also known 

 as the amyloid, waxy, or lardaceous kidney. This 

 kidney is enlarged and quite pale; its consistence is 

 firm, and the section has a peculiar, glistening, bacon- 

 like appearance. The glomeruli stand out as bright 

 points upon the surface ; the capsule peels off easily 

 and leave a smooth surface, lodin applied to the 

 surface of the section turns the diseased portions a 

 mahogany-brown color. The change in this di>easeis 

 most marked in the glomeruli and the blood-vess< 1 

 walls, but may be found elsewhere ; it is most fre- 

 quently due to prolonged suppuration, hone and joint 

 disease, tuberculosis, syphilis, malaria, and mercurial 

 poisoning. The onset of chronic Bright's disease is 

 usually insidious, and may only be indicated by slight 

 puffiness of the eyelids or the ankles, shortness of 

 breath, dull and persistent headache, disorder of vision 

 and hebetude. The pulse is one of high arterial ten- 

 sion, and there is hypertrophy of the left ventricle of 

 the heart, especially in the case of the contracted 

 kidney; there is frequent micturition, progressive 

 anemia, dryness of the skin, indigestion, and a ten- 

 dency to uremia. The urine i- always scanty with the 

 large white kidney, but abundant with the other forms 

 of the disease. The specific gravity and the reaction 

 vary ; occasionally there may be present a small 

 quantity of blood, and albumin is always present at 

 some period in chronic Bright's disease. The quantity 

 of albumin is very large in the large white and amy- 

 loid kidneys ; very slight in the contracted form. Mi- 

 croscopically, the urine contains renal epithelium, 

 granular and fatty matter, and tube-casts. The latter 

 are most plentiful in the large white kidney, but are 

 never so numerous as in acute nephritis ; they are 

 granular, fattv, and hyaline in nature. A frequent 

 symptom of chronic Bright's disease is the so-called 

 " albuminuric retinitis" in which condition there are 

 ecchymoses of the retina, together with white glisten- 

 ing spots, most numerous near the macula lutea, and 

 frequently arranged in lines like the radiations from 

 a star. This i-, diagnostic of chronic renal disease. 

 The prognosis of chronic Bright's disease is bad, death 

 eventuallv resulting from uremia or apoplexy.
