364 On Ammonia in the Urine in Health and Disease. [May 30, 



found with nearly normal temperatures ; but when the total quantity of 

 urine is estimated, it is seen that such normal temperatures (as in diabetes) 

 go with increased ammonia. 



F, condition of shin. The largest excretion occurred when the skin was 

 moist. 



G, condition of tongue. Excretion largest with moist tongue. 



H, condition of bowels. Ammonia was slightly in excess when the 

 bowels were open. 



I, diet. Even in various diseases the amount of ammonia was very 

 much larger when the diet was full and included stimulants. 



K, medicines. Only acids and alkalies contrasted. The amount was 

 nearly double in the case of acids. 



III. Special Diseases. 



A, acute rheumatism. In nineteen observations ammonia equalled 

 0-0684 gr. per 1000 grs. 



= 1*7955 gr. per diem. 

 Considerably less than normal. 



B, erysipelas. In ten observations 



NH 3 =0 0402 gr. per 1000 grs. = 1*0552 gr. per diem. 

 Very much under health. 



C, diabetes. In seven observations, with an average of 240 oz. of 

 urine per diem, 



NH 3 =0*0348 gr. per 1000 grs.=3*654 grs. per diem. 

 Considerably in excess of healthy urine. 



D, smallpox. In eleven cases 



NH 3 =0-0627 gr. per 1000 grs. 



E, enteric fever. In eleven cases 



NH 3 =00543 gr. per 1000 grs. 



F, typhus fever. In two cases 



NH 3 =0*0435 gr, per 1000 grs. 

 X.B. — The results of B, D, E, and F, considering that the amount of 

 urine will be nearer 25 oz. than 60 oz. per diem, show that the amount 

 of ammonia excreted in these diseases is actually less than one fourth that 

 of health. 



G, cancer (verified by post mortem examinations). In five observa- 

 tions 



NH 3 =0*0918 gr. per 1000 grs. = 2-4097 grs. per diem. 



H, heart disease (chiefly valvular). In ten cases 



NH 3 =0*0927 gr.'per 1000 grs. =2*4334 grs. per diem. 



I, chronic alcoholism. In four observations 



NH 3 = 0*1065 gr. per 1000 grs. = 2*7956 grs. per diem. 

 N.B. — G, H, I sho.v ammonia very nearly normal, as might be expected. 

 K, chorea. In six observations 



NH 3 =0'09 gr. per 1000 grs.=2'3625 grs. per diem.
