THE AUTOGENOUS DISEASES. 355 



which he proposes is less food, especially less nitrogenous 

 food, and more exercise. That some substance resulting 

 from the proteids of the food is the cause of this trouble 

 Brunton thinks is evidenced by the fact that the weak- 

 ness and languor are apparently less after meals consisting 

 of farinaceous foods only. 



That peptone finds its way into the general circulation 

 frequently is shown by its detection in the urine in many 

 diseased conditions, some of which are infectious and others 

 autogenous in character. However, propeptonuria, or albu- 

 mosuria, is more common than peptonuria, and we have 

 already seen that many of the bacterial albumoses are among 

 the most highly poisonous bodies known, but the action of 

 the albumoses formed during digestion has not, so far as 

 we know, been studied. The valuable work of KtJHNE and 

 Chittenden on the chemical character of these bodies 

 should be supplemented by a thorough investigation of their 

 physiological effects when injected into the blood. It is more 

 than probable that valuable information would be secured _ 

 by such studies. That albumose is frequently found in the 

 urine is shown by the following list of diseases in which 

 it has been observed, given in the last edition of the work 

 of Neubauer and Vogbl on the urine : Kosner has 

 found it in spermatorrhoea ; Koppen, in mental diseases 

 without spermatorrhoea ; Kahler, in osteomalacia; Benoe 

 Jones, in multiple myeloma ; Senator and others, in 

 dermatitis, intestinal ulcer, liver abscess, croupous pneu- 

 monia, apoplexy, vitium cordis, resectio coxse, parame- 

 tritis, endocarditis, typhoid fever, nephritis, phthisis, etc. ; 

 LoEB, in measles and scarlet fever ; Leubb, in urticaria ; 

 and LassaEj after inunctions of petroleum. Kottnitz, 

 FuESTNER, and others, find albumose frequently in the 

 urine in mental diseases. Evidently, there is much to 

 learn from the study of the conditions accompanied by the 

 elimination of the albumoses in the urine. It is more than 

 probable that the acute Bright's disease following scarlet 

 fever, diphtheria, and the other acute infectious diseases, 

 owes its existence to the poisonous albumoses of these dis- 

 eases. Prior has recently shown that undigested egg
