STRONG AND CROWELL. 



vessels of the glomeruli are much congested and the cytoplasm 

 of the epithelial cells of the tufts is frequently granular 

 and sometimes vacuolated. Some of the glomerular spaces 

 contain a material similar to that described in the convoluted 

 tubules, but no cellular exudate. The cells lining Bowman's 

 capsule are sometimes high and swollen. In the pyramids the 

 cells of the excretory tubules are intact and no casts are seen, 

 but the tissue between the tubules is very (edematous. Sections 

 stained with Sudan III show no fat. 



Stomach and duodenum. — The sections show hsemorrhages in 

 the mucosa without inflammatory condition other than slight 

 catarrh. Marked prominence of acidophilic parietal cells is 

 observed in the pyloric glands. 



Nerves. — These were fixed in Miiller's fluid and prepared by 

 the Marchi method for the study of the degeneration of nerves. 

 The hsematoxylin and eosin stain was also employed. 



All nerves examined (vagi, phrenics, anterior crural, popliteal, 

 and sciatic) show equally marked changes. The degeneration of 

 the myelin sheaths is very advanced and a large majority of the 

 fibers are affected. In longitudinal sections this degeneration 

 is shown after the Marchi treatment to consist of a marked 

 swelling and fragmentation of the myelin sheath and its collec- 

 tion in masses and globules, giving a varicose or honeycombed 

 appearance to the fibers. No leucocytic infiltration or prolifera- 

 tion of the nuclei of the neurilemma is seen in the sections. Cross 

 sections show fibrils, some partly and some completely surrounded 

 by the degenerated sheath. There is apparently some fragmen- 

 tation of the nerve fibers themselves. (Plates IV, V, VI, and 

 VII.)
