Here, again, an increase of tlie carbhydrates, thongli 

 accompanied bj a slight decrease of the protein, changed 

 a loss of flesh into a gain, as well as diminished the pro- 

 tein consumption. 



Further confirmation of this effect of the carbhydrates is 

 found in the frequently observed fact that in the great 

 majority of cases where the supply of albuminoids is suf- 

 ficient to cause any production of flesh, the greatest relative 

 gain is produced by rations having a wide nutritive ratio, 

 that is, a large proportion of carbhydrates to albumin- 

 oids. 



This fact is well shown by the following selection from 

 the experiments of Schulze and Marcker Q^e* eit) on sheep, 

 which are arranged according to the nutritive ratio. They 

 were not all made on the same animal, nor at the same time, 

 and are only comparable in a general way ; but, being toler- 

 ably numerous, they are sufficient to illustrate our present 

 point. The results are per day and head. The protein in 

 the daily growth of wool, amounting to about five grammes 

 is not included in the gain of protein.
