ished supply of water is also one of the features of OERTEI/S cure, 

 especially in certain cases. The average amount of the various 

 nutritive substances supplied to the body in these three cures is as 

 follows, arid we give also for comparison in the same table VOIT'S 

 diet necessary for a laborer.

If the fat in all cases is recalculated in starch, then the pro- 

 portion of the proteids to the carbohydrates is :

In all these cures for corpulence the quantity of non-nitrogen - 

 ized bodies is diminished as compared to the proteids; but chiefly 

 the total quantity of food, as is shown by the number of calories, is 

 considerably diminished. 



HARVEY-BANTING'S cure differs from the others in a relatively 

 very much greater amount of proteids, while the total number of 

 calories in it is the smallest. On this account this cure acts very 

 quickly; but it is therefore also more dangerous and more difficult 

 to accomplish. In this regard EBSTEIN'S and OERTEL'S cures (espe- 

 cially OERTEL'S), having a greater variation in the selection of food, 

 are better. As the adipose tissue has a proteid-sparing action, we 

 have to consider in using these cures, especially BANTING'S, that 

 the destruction of proteids in the body is not increased with the 

 decrease in the adipose tissue, and one must therefore carefully 

 watch the elimination of nitrogen by the urine. All diet cures for 

 obesity are moreover, as above stated, starvation cures ; and if the 

 daily amount of food required by an adult man, represented as cal- 

 ories, is in round numbers 2500 calories (according to the average
