The malt is intended as a food and also to act upon the starch in the 

 oats and convert it partly to maltose, in wliich form the oats are more 

 easily digested. This combination is made after the formula of Liebig/ 

 only oat meal is substituted for wheat meal. Our method of preparation 

 was as follows: The malt was kept separate from the other ingredients. 

 Three ounces of the oat meal-blood-potash mixture were converted into 

 a paste with cold water, and then sufficient water added to make 1 quart, 

 and enough prepared at one time for each twenty-four hours. This mix- 

 ture was cooked or heated very warm for fifteen minutes and then 

 cooled to 100° to 120° F. One ounce of ground malt was then added for 

 each quart of the first mixture, and the latter allowed to stand for one-half 

 hour. It was heated again to near boihng, then cooled and fed milk- 

 warm. The basal ration of skim milk was added just before feeding. 

 The reason for heating to near boiling or to boiling before adding the 

 malt is to gelatinize the starch, which enables the malt to act on it more 

 thorouglily.
